Engineering Perfection: Marklin E 18 in ‘Z’!

I recently purchased a rare variant of the E 18 electric locomotive in Z by Marklin, it arrived as a used working model, but with a fair amount of dirt and hairs strangling the axles. Cleaning it up included taking it apart and removing the dirt and grime under the hood, but it also included removing excess oil that even found its way under the circuit board. No HOS (hardened oil syndrome) to deal with, but over oiling has its issues including attracting dust and damaging the motor, in this case not much damage occurred to the locomotive.

This post is not so much inspired by the normal reporting of mini-club locomotive maintenance instead it is one that was inspired by the brilliant engineering and design of the E 18 for mini-club.

Marklin does not apply the same rules and principles when designing a mini-club loco: same motor and chassis different shell, no Marklin designs each locomotive class from the ground up thereby insuring the prototype is accurate in 1:220 scale and operates as flawlessly as we have all come to expect from mini-club operation!

Marklin 88082: rarest E 18 variant from 2004

The E 18 is an example of one such mini-club locomotive design that incorporates unique engineering and casting that is also meant to be taken apart and repaired when the need arises.

Taken apart this locomotive has a lot of parts that work flawlessly in the assembled locomotive including two gears that sit on posts within the frame and two large gears allowed to float on their axles.

above photo: right- small metal gear sits on post within frame as well as a second one not pictured, 2 additional gears one synthetic with two sets of gearing sit posts that are inserted through frame body

above photo: left- drive wheels that float on their axles pictured left are assembled in slots on the motor end of frame, two drive wheels right use thinner gears that are permanently fixed in the center of axles which are thicker than floating axles.

The design concept is simple: gather electricity from the wheels by way of a circuit board, the turning worm gear (transmission) on the motor engages with gearing that engages all the way down to the wheels thereby making all wheels drive wheels except for the pilot wheels.

Note: plastic mini-club loco shells are removed without damage with super thin synthetic guitar picks, do not use metal screwdrivers famously illustrated in the Marklin instruction manuals boxed with the locomotives.

With the shell off the cast wheel details are carefully pulled off, they are simply held onto the frame with posts!

Circuit board is not held under clips as with other locomotives, and one screw is all that is required to hold it in place.

The motor is screwed to the frame with 2 brackets each installed with two screws. Note: if you are at this point in restoration it is advisable to remove the motor and clean the frame under it. It is also a good idea to test the motor out of the frame, inspecting the brushes is also a good idea at this point.

After cleaning all the gears replace in the frame with the two gears on posts first followed by the large gears (2 gears that are designed to float on their axles are installed on the motor side of the frame, thickness of these axles also match the machining on the frame).

Note: use care to prevent bending of the copper leads on sides of frame.

Final steps: clipping on the wheel detail sections and then shell: Voila!!!!!

Variants of the German E 18 in mini-club:

Marklin class E 18 for DB (88080) Era III:

Marklin class 118 for DB (88081) Era IV:

Marklin class 1018 for OBB (88082) Era IV:

Marklin class E 18 42 for OBB (81441: trainset with coaches) Era III:

Siding: no other Z scale loco is designed to be taken fully apart and easily assembled as mini-club: diesel and electrics are easier than steam and non articulated are easier than articulated.

Siding: all class E 18’s are sold out at the factory, but Walthers still has the 81441 trainset available with beautiful green livery and 4 skirted coaches.


Micro-Structures and American Prototype Architecture for Z

Miller Engineering released a line of buildings kits years ago called Micro-Structures designed along the lines of typical architecture found in many small American towns. If you visit Main Street in many USA towns the original buildings haven’t changed much since they were built in the late 19th century, the towns themselves have changed dramatically and some buildings have gone through facelifts and demolition here and there, but for the most part the old buildings are intact thus modeling most any era of American railroading is possible with these building kits.

V101- Victorian House: “Empire” (note: additional scoring is required with this kit)

V606- Victorian House: “The Victoria”

The concentration of the line was on Main Street, but it also included a few Victorian houses that rounded out the line nicely. Note: I am using the past tense because unfortunately the line was discontinued with only a few new kits available here and there from dealer old stock. Ebay is a good source as is I found a local dealer who had a few left over kits which were very popular in their day and should be today; they are well designed in historical scale and detailing plus well made out of heavy gauge etched brass.

303- K.C.’s Hardware Store (note: features printed windows with store logo) lime sometimes appears over time in mortar joints and bricks, I applied diluted white paint followed by wiping off to give this effect

404- The Triangle Hotel & Bar (note: features printed window masking for the street level windows as well as clear acetate for the other windows) building as it appears right after painting but before window glazing. Typical building type for a mid size town, but this design first appeared in NYC, that building is called not surprisingly the “Flat Iron Building”

505- Crestline Theater (note: two options for marquee include a solid marquee with etched movie now showing or a cut out marquee designed to hold a paper now showing sign, this building was built with solid marquee) detailing is so good with this kit that a depiction of can lights above the doors is included that look great lit

With a few exceptions the kits go together quite easily, but I found the large Victorian “Empire” House to have shallow scoring lines for bending in this case further scoring was required. Overall the Empire house was the most difficult of the group to make.

606- Pitman’s Deli (note: excellent detailing with printed store windows and beautiful awning, plus recessed door)

I found some kits came with acetate for the windows while others did not, and a couple had just enough for street side windows with very nice printed signage.

901- City Fire Station (note: I tried building this kit years ago with the recommended Super Glue, it was a disaster and tried these kits again until this Fall. Solder is the way to go for me!)

One obvious advantage with these kits is lighting, they will not leak light as the metal is opaque, but you must fashion windows masks or partition walls for realistic effects.

801- Townhouse #2 (note: under construction the model is assembled but prepping it for painting will include sanding solder joint smooth and bending to make the building sit flush, followed by a good cleaning with diluted Dawn, warm water and a soft toothbrush, green residue on building is flux which washes off easily with warm water and original blue Dawn)

Prepping the kits for assembly takes time, any rough edges must be sanded or filed. And after assembly the buildings need thorough cleaning to remove solder flux or other debris. Super Glue or soldering are the choices for assembly, but I prefer soldering due to the speed and control of this method. Soldering is easy if you use flux in addition to the solder with flux. I solder at 750 degrees and place water soluble flux at the area to be soldered with a toothpick. Note: solder melts and follows the source of heat, try to avoid applying solder directly to the soldering iron tip.

100- City Scoop (note: this is the only kit that requires Super Gluing, it is made of stainless steel and solder will not adhere) this building features great detailing including ice cream machines and work table on the interior, plus picnic tables, air conditioning unit and trash cans on the exterior. I had fun with this kit and painted a whimsical ice cream cone. I also left the interior natural stainless steel, but I painted the ice cream machines with silver solvent based paint and painted the outer edge of the ice cream cone with metallic copper solvent based paint just to catch a sparkle there. (note: if you discover a build-up of Super Glue after its cured it can be removed easily with a razor blade and wear gloves working with Super Glue!!!!!!!!!!)

Note: preparation of the building will include sanding or filing smooth any solder ridges or residual glue that will otherwise show up under a thin layer of paint.

Window glazing is glued in place after painting with 5 minute epoxy. As stated earlier acetate was missing in some kits I bought or not enough was included, if you build Archistories kits use some of the leftover acetate as they are very generous at Archistories.

5 minute epoxy might be the best option for securing these buildings to the layout if it is portable otherwise they sit flush to the surface and anchoring may not be required.

The small buildings in this line-up require simply cementing window details in place then folding buildings sections together and cementing. The roof requires bending along sides and molding embellishments before attaching to building. Note: fold the front section of roof first before side sections, a separate folded section goes over the front of the roof thereby giving a nice finishing touch thus do not cement the roof until this part goes on! Note: everything is outlined well in the instructions, my notes are simply to highlight important aspects that arose for me.

These buildings look better in person, and even better with a GG1 rolling by capping off the hard work and meticulous attention to detail involved with their construction. And your family will be proud of your good fortune!

No complaints about these kits, they were fun to build and modify as needed!!! And soon to be very collectible!

Siding: essential brass bending tool is “The Bug”

Cranes Cranes Cranes! by Peter Behnke

Awhile back I featured a MOW vehicle for the SBB available as a printed shell through Shapeways, it is the design and handiwork of Peter Behnke who’s designs for numerous interesting Z are available at Shapeways.

Mr. Behnke prior to the printed Shapeway models produced small batches of nickel etched build kits for rail vehicles and industrial machines including cranes here we have four of those cranes:

1. 1944 KRUPP ARDELT Dier 1 




Finely detailed etched kits originally delivered without assembly instructions are now available with limited instructions from Scandinavian Shops or qualitytoytrains on Ebay. Numerous filigree parts and thin metal make for some challenges, but they get easier after the first one or two as does most things. Various levels of expertise will be on display for those who take on these kits including soldering and painting skills, but most importantly prepping and bending parts before assembly.

First: orientation to the parts sheet or as one person has said looking at a puzzle with no idea how it goes together

Second: separate parts from sheet and gently sand any rough edges

Third: gently fold parts following photo guides here or in the instruction sheet provided with current purchases through Scandinavian Shops *each kit will have unique challenges and instructions will become more of a distraction from common sense as anyone may attest that assembles these intricate and delicate kits

note: best tool for bending etched metal parts is “The Bug”, it is part of my essential Z toolbox:

The Bug is available at

Fourth: soldering or super glue are the choices for assembling, I prefer solder because it is quick and gap filling

Fifth: a cleaning phase follows before painting, I use original Dawn liquid (blue) diluted in warm water and using a soft toothbrush gently go over all surfaces to clean off any debris or flux followed by thorough drying

Six: determine your paint color and either spray or brush water based paints, I do not recommend solvent based model paint for these kits, I have found it easier to apply layers of color with water based model paints and the flat surface appearance takes better to aging and weathering

Seventh: spray a diluted water based lacquer over the model to add durability to the painted surface followed by rigging the lines from hook to winding drum

Note: the kits do not provide some required parts including pulley wheels so some extra effort is required to fashion the essential parts for securing rig lines

Note: weighting the cabin is required for some cranes, test before securing cabin to deck, if it topples over maybe cement a small hex nut inside

Note: cranes can be assembled to allow the cabin to rotate on the deck of the crane, pre-drilled holes are provided, but tiny machine screws are not, I determined the placement of the cabin and soldered in place, I also soldered in place the boom which can also be assembled to move, but I do not recommend it: parts are to flimsy for continuous movement at the joint where the two meet

Note: the crane boom in all the kits is one piece featuring bending seams, I soldered all seams to ensure a solid construction, due to the nature of the parts SuperGlue will not work for this step as a gap filling material is required.

Note: soldering is easy with flux, I use water based flux applied to the area I want to solder with a toothpick, heating the material with a soldering iron makes the solder flow toward the heat and to the area to be joined *solder is not applied directly to soldering iron tip unless the area to be joined is too space restrictive *solder with a flux core is recommended with additional flux applied to the area to be soldered

Siding: the right tools make all the difference as with soldering the very best tool I have found is the Hako FX-951 soldering station, it features interchangeable tips, solder resistant pad, sleep mode with iron craddle, and multi function control box *best tool I bought in 2017!!!



Marklin Insider 88507: cab forward BR 05 DRG

One of the more interesting Z items released in the past few years was the 2014 Marklin Insider “Fine Art” edition 88507. The release of the BR 05 Era II cab forward steam locomotive marked the first and hopefully not the last special “Fine Art” releases, it was produced in brass with numerous add-on parts and filigree spoke wheels. Motive power is provided by new coreless motor with bell shaped armature. Available to Insider Members, the release was presented in special packaging including wooden box and certificate. Possibly due to the high price of this locomotive some were not delivered and a few are still available from dealers including Reynauld’s in IL.

Built in 1937 the BR 05 003 was the only cab forward design produced of the class 05, it resumed post war service in 1950 after restoration work was performed by Krauss-Maffei, it was retired in 1958. Cab forward steam locomotives are a technical marvel which allow better visibility but require larger crews.

The Marklin model is 5 inches in length over buffers, due to brass casting it is heavy featuring a robust motor thus mechanically sound and smooth running. If the locomotive is displayed it can be fitted with full skirting provided with the model or skirting can be removed for running on track with maximum radius of 195mm, with full skirting the locomotive can only go straight. Spacing adjustable between locomotive and tender. As with past historical releases Marklin has included a cast metal builder’s plate for Borsig.

BR 05 003 was scrapped in 1960, photographs and technical models provide the historical record of this interesting locomotive.

Siding: joining the Marklin Insider Club is less than a $100 a year, member benefits include the annual Club Car in the scale of choice, Marklin Insider Magazin, Insider Model reservation certificate, Insider Club News, annual catalog, laminated club card with member’s name, and “Year of Marklin” DVD.




Railex versus Z-Modellbau: Kof II showdown

Until Z-Modellbau took the challenge to manufacturer a Z Kof II with a Motor (!!!!) our choice was limited to mechanical rolling non-motorized Kof’s by Schmidt and Railex.

The Railex example here is cast brass (red paint scheme lettered for DB with open cab and black running boards) with fine detailing inside the cab, it was a very good example of a Kof II that Railex produced along with variations of this type.

Headlamps are non-working in both locomotives but Z-Modellbau rendered them white in perfect circles versus Railex which are hand-painted silver.

What to do with a non-working model train: use it of course! Before brushless motors manufacturers of Z gauge had certain limitations placed on their ambitions. Z gauge is already small in size so therefore modeling the smallest prototypes yield problem after problem including where to put a motor and gears. The solution with their larger steam locos and tenders was locating the drive mechanism within a passenger or freight car hence they were called “ghost cars” because they became hidden locomotives, but they allowed the locomotive to pull cars so to speak figuratively not literally. I collect Railex, they are beautiful and fun to behold. As for ghost cars I have never owned one, I understand they can be temperamental and many I see for sale are offered “not working”. Ghost cars can be built by industrious engineers with a clever creative side which describes most of us Z-scalers, if you choose the to take the challenge the rewards are big and stalled trains from 19th century Germany may come to life on your railway line.

Photo: no couplers on Railex, Z-Modellbau uses Marklin compatible couplers of their own design that unobtrusive in this small loco

Now the time is ripe for ambitious manufacturers to create smaller locos in Z that function, today brushless motors from Switzerland are available in a variety of small sizes so releasing new locos with this motor should be easy? Wrong. From idea to final market ready model is a design and manufacturing “Matterhorn” so to speak. Having the idea is the first step followed by researching the prototype’s blueprints, putting into scale, designing the parts and assembly. Every step is time consuming and difficult with a fair share of creative thinking, ingenuous problem solving and sheer expertise in tooling and production. The latter always flabbergasts me, how can anyone be gifted with such abilities that tiny tiny tiny details appear in such small locos at the same time concealing their build.

With the Railex Kof which is cast with add-on parts in cast brass the model is beautiful with a securing plate screwed to the undercarriage that simply holds the wheel-sets on: simple and beautifully designed. This example does not have couplers thus making it a stand alone model train.

Photo: Railex Koff hauling livestock boxcar both lettered for DB

The Z-Modellbau Kof II for NSB has an enclosed cab with glazed windows and their own unique design for a Marklin compatible coupler. A 10 volt coreless motor runs the show including gearing that allow smooth acceleration and deceleration but without working headlamps. Headlamps are beautifully modeled as if lit. Locomotive is weighted and balanced due to its metal nature throughout so pulling power is very good.

Photo: Railex Kof II is true to prototypical scale giving the boxcars the impression of great size

Small locomotives serve very important functions including shunting and branchline while others not covered here serve MOW (Maintenance of Way) service, they (speeders) are still smaller than the kofs  with one purpose: track inspection.

Siding: seen here are the two livestock boxcars comprising the Marklin 2 car freight set: 86602. For the first time this car type features interior detailing in the form of gates, it also includes laser cut build kit for loading ramp and movable fence sections.

Z-Modellbau builds the legendary ML 2/2 in Z!!!!!!!!!!!!!!!!!!

Maffei built the ML 2/2 steam locomotive in 1906-1908, Z-Modellbau built it first as a Z scale model. The observation has been made many times equating the appearance of early German steam locos with toy trains, but the ML 2/2 was a hardy locomotive that proved it’s worth.


Built for the Bavarian State Railways the ML 2/2 was equal measure to the PtL 2/2 built by Krauss. Service duties included all such description on branchlines, and it could be operated by a single driver due to its semi-automatic gravity fed firebox. 24 locos were produced until it was retired in 1924.

Z-Modellbau has done it again with one of the finest Z scale locos ever available, the fine detailing of this loco has no rivals. And it is very small and true to scale with the prototype’s external cylinders modeled with smooth moving side rods of an ingenious design. This little gem is all metal construction featuring brushless motor and window glazing in the cab.

The ML 2/2’s place in history has been preserved in Z by Z-Modellbau, every inch of this is a masterpiece even though it’s total length is less than inch.

Running performance is superb at slow idle through full throttle.

Marklin’s 82391 (2005) high capacity coal hopper lettered for K.Bay.Sts.B is a perfect choice for this loco as well as Marklin small loco repair shed 89805.

Photo: here the ML 2/2 details are seen with coal bin in cabin roof and Marklin compatible coupler.

The scaling of Z-Modellbau locos creates a dramatic appeal on the layout due to their small size. Juxtaposed next to larger more powerful stream loco the ML 2/2 will stand out next to those towering express locos. Train sheds and buildings will also offer interesting juxtapositions and already there are buildings by Archistories and Marklin that fill in this time-frame for authentic prototypical railway scenes.

Photo: on a siding or near a loco shed the idling ML 2/2 will have great appeal on rural railway lines hauling passenger and/or freight.

New Insights: Faller 282711 “Klingenberg Station”

A couple of years has passed since Faller released the card-stock kit for Klingenberg Station, it is remarkably similar to the plastic kit “Guglingen Station” with exceptions. The exceptions include new use of laser cut card-stock with a combination of laser cut wood parts and plastic.

Laser cut card-stock has evolved at Faller and currently there have been a number of them released over the years of entirely new designs even for urban settings. The neat innovation with Faller is the use of masking, it was originally useful/essential for lighting plastic buildings to avoid glowing of the whole building, but the original masks served double duty and introduced another innovation with window details: drapes and curtains. Card-stock is opaque so no glowing naturally occurs when lit, but Faller continues to include masking simply to add interest to the windows of their kits.

Note: LED’s are recommended to for lighting Faller buildings due to their brightness and dimming controls. LED’s are also cool versus conventional hobby lighting which give off a lot of heat. Lastly LED’s will last far longer than traditional lighting.

This first kit included plastic roof sheathing which I painted to lessen the look of plastic and the wooden parts are a beautiful texture and color hard to simulate in paper. A good design based on the original plastic kit available for many years this transitional kit to finer detailed laser cut cardstock was a very good attempt to keep pace with the growing trend toward professional cardstock construction. Faller continues to combine laser cut wood parts into these kits, and they continue to innovate with new kits each year.

Siding: this building could be a very good contender for modeling a Scandinavian themed layout?

Marklin’s New Brushless Motor: Good News Follow-up!!!!!!!!!!!!!!!

The other day I submitted a post for your review which posed questions about the new brushless motors making their appearance in Marklin Z locos. And one example of a new release steam loco that had an operating issue that I included in that review.

The steam loco is the Bavarian 88923 with the very detailed running gear and side rods, out of the box it inexplicably stopped in the forward direction but ran well in reverse. Today I decided to problem solve the running performance and discovered some interesting things about the new motor.

Note: roller stands are great on those occasions a loco needs testing, they keep it in place so inspecting what is wrong is easy. Many companies make roller stands, this one is by Marklin (89932).

The new motor for the 88923 is a solid case brushless type that attaches to the end of the loco chassis in much the same way as the former 3 and 5 pole mini-club brush motors: a permanent gear mounted to the motor engages with the transmission gear whose other end is the worm gear which engages with the gears that move the wheels. The motor is secured to the chassis with a single screw like before, but the new motor has two alignment pins that engage in the end of the chassis which place the motor and chassis in precise alignment. Out of the box this loco ran rough in forward and stopped, but it ran well in reverse. I took the loco apart and removed the motor and transmission gear, I carefully reinstalled the transmission gear after applying a drop of oil on the worm gear and opposing gear, I was careful to align the two pins on motor with chassis applying a little pressure. It took 4-5 tries after moving the gears a little bit to properly seat the chassis and motor, but the tolerances seem to me to be more stringent with this new motor. The old motor assembly of the brush motors seem to have a little wriggle of the shaft and transmission gear alignment which suited that design well, but I believe the new motor assembly is a tighter system at this connecting point between motor/transmission gear/chassis. The glitch I experienced I believe was a very slight misalignment during assembly. I am happy to report that the loco runs like a dream, it is quiet and runs at very low speeds.

Photos: under the hood of the 88923 shows wire leads from motor soldered to chassis pick-ups which are taped down to facilitate removal and installation of shell. Note: solid motor case with no access points for oiling, this is a maintenance free system. Normal sparse oiling of wheel-sets still applies. Hiding wires will be part of this new world of mini-club, but this example has deep channels on each side to hold the wires flush and out of sight.

The new loco for Kay.Bay.Sts.B is not only a great runner, it is a wonder to watch the lively action of the side rods. The shell detailing and paint scheme complete this work of art, it is spectacular!!!!

Note: instructions that were packed with my loco show it with the old 5 pole E251 202. The installation of the new motor in this loco may not have been originally planned, but you will know which motor you have in this loco by looking at it: solid case is that of the new brushless motor original 3 and 5 pole motors had a center bushing that required a very lite drip of oil periodically.

Link: original instructions for the 88923 showing 5 pole brush motor thus incorrect oiling instructions are outlined

Photo: view of two Bavarian class S 3/6’s with new brushless motor (bottom: 88923) and former brush motor type (top: 8108)

Siding: motor upgrades have been available for all the mini-club locos since the 5 pole was introduced on the BR 143 in 1998 with some requiring soldering, I don’t think future upgrades with the brushless motor will be available to convert this locomotive class in former releases due to the machining of the frame with the 2 motor alignment holes.

FR Week: Interregio coaches 46.220.42 + 46.221.42

Several firsts with the recent release of FR’s SJ coach sets, they are the first coaches designed and manufactured by FR, and they are the first SJ coaches modeled for Z gauge. Plus these sets include interior detailing first introduced by Z-Bahn a number of years ago, now it is a feature of new releases by Marklin and FR this being an example.

The two coaches set follow the attractive paint scheme blue with red stripe. Any paint scheme for the RC2 and 3 locos can prototypically pull these cars, it is up to preference. The coaches feature fine detailing and prototypically depicted metal window frames.

46.220.42 includes 1- each 1st class and 2nd class type 1960- talsvagn Interregio A+B

46.221.42 includes 1 2nd class and 1- 1st/2nd class type 1960- talsvagn Interregio A/B + B

Note: yellow stripe indicates 1st class and turquoise represents 2nd class.

The model has a unique solution for the car weights, it is seated on the undercarriage and features fine detailing in cast metal. Car sets are delivered without interior lighting, but lighting can be added and FR has provided pre-drilled holes in the trucks to allow for wiring.

Siding: several paint schemes have been proposed for later releases, they will represent various time-frames in SJ passenger travel.

Shapeways: New Directions in Z Modeling

3-D printing is all the rage these days, any manner of thing seems to be offered by this new technology. And now Z items are available through the company Shapeways. I hadn’t even thought about searching for such things but a few months ago I came across the Shapeways website. My Wife and I had a day off in some far off land so I had time to check out the 12 pages of Z gauge offerings by a number of designers, and I found it very enjoyable and ordered one. The item I ordered was a German class 701 catenary maintenance locomotive, it arrived packed in a sturdy box by the time we got home from our trip.

It is interesting to order from Shapeways, items are printed on demand with the disclaimer that the order maybe cancelled if Shapeways feels the item is too delicate to print so presumably not everything is available. The item I ordered was printed, and I am very happy with the finished shell. The plastic is translucent with a slight texture that will take paint well. Because of the translucent material lighting the loco will be disappointing unless a solution is made by masking (later problem to work through).

The locomotive came in two parts including the main shell and service platform. Detailing and design is quite excellent including warning beacon lights and roof top observation window. Shell has the same specs as the standard Marklin railbuses so adding a chassis and motor will be easy. A small hole is included in the roof to accommodate the single arm pantograph. Challenges for completing this project include painting and thus masking for three separate painting phases: safety yellow, gray and silver. Note: I find it easier to paint the dark color first inside and outside shell, finishing the roof as the final paint is what I do. Brushing the silver hardware for windows and black paint for buffers plus any touch-ups before following up with the final matte clear coat. Much easier to airbrush using water based paint diluted to flow through the airbrush used. Attaching the work platform permanently with 5 minute epoxy only, but the cool loco is designed for a pivoting work platform secured with a screw.

The prototype well depicted by the 3-D printed model as can be seen with two paint schemes by Marklin and Trix, and the roof observation hood as seen in the third photo of the prototype:

Notes on Shapeways products for Z: many curious items are offered including autos and loads as well as buildings, locos and rolling stock. These are projects that need to be completed and some that are offered will be more successful than others.
