FR’s 1960 Talsvagen coach sets: 46.220.32 + 46.221.32

Furthering FR’s offering of 1960 Talsvagen coaches for SJ include the recent releases of 2 car sets: 46.220.32 includes 1- 1st class coach + 1- 2nd class coach and 46.221.32 includes 2- 2nd class coaches.

46.220.32

46.221.32

Painted and lettered for SJ following the paint scheme of the early 90’s these coaches also include the new logo: modern take on the winged logo dating back to the late 19th century which originally featured a railway wheel with chamfer and wings as seen here in a very early hat badge alongside a 1950’s updated hat badge:

Elegant bright colors exemplify modern SJ paint schemes following the originating paint scheme of red/brown with a simple boxed in SJ logo branding the 1st examples of 1960 Talsvagens.

A custom light panel comprising LED’s designed and manufactured by Passmann is available as an accessory on the FR website. Installation is not hard with the right tools including soldering iron, tweezers, magnifying goggles, and tool (Bug bending tool) for precision bending wheel wiper whiskers for electrical pick-up.

Note: Harald Freudenreich can deliver the coaches with bogies and roof panel removed to make installation of the light panel easier versus disassembling the coaches for the upgrade.

Siding: Bug bending tool is an indispensable tool for etched metal build kits, I haven’t found anything quite like it and I would highly recommend this item for every Z gauger’s tool box.

 

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 ZScaleHobo.com. 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 

2. TAKRAF RDK 160

3. TAKRAF RDK 280

4. TAKRAF RDK 300

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 ZScaleMonster.com: http://www.zscalemonster.com/the_small_shop/

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!!!

 

 

Repainting 8135 coaches for the SJ: Part 3

This is the 3rd and final post on the repainting and lettering of the Marklin Dompfeil train set (8135) for the SJ.

Before (Marklin 8135):

After (SJ coaches using FR decal set):

At the start of this project I had never repainted a train car before or operated an airbrush thus much was learned.

SJ coaches in z scale have been extremely limited, FR released a type litt AB8k 1st and 2nd class in a single release of 30 only, FR 46.299.00 was based on a German built coach that was used on a ferry service. In order to accurately represent this coach FR modified a Marklin coach that was shortened by one window.

photo: FR 46.299.00 (edition: 30 total) – SJ type litt AB8k 1st and 2nd class coach

For those interested in SJ modeling in z there are numerous locos and freight cars by FR, but scant few passenger coaches until FR released a decal set several years ago intended for the Marklin 8135 coaches, these German built coaches for the Dompfeil train set were likewise used on the SJ.

The process of producing a set of 4 coaches started with disassembly of the coaches followed by stripping, in this post the final stages are documented including masking, painting, and lettering.

Identifying the sections to paint include the undercarriage, sides, and roof. The roof is a clip on part, it does not require masking unlike the shells. Painting two colors of the same part requires masking, I decided to start with the undercarriage and vestibules color, I sprayed the entire shells with this color with no masking.

Before applying the brown paint I masked off the vestibules and undercarriage. The masking material is similar to common masking tape, but it is markedly thinner with a slick surface, it also comes in a variety of widths. I chose masking tape of 6mm width manufactured by Tamiya.

After paint is dried the masking tape is removed, for areas not protected by masking retouching maybe required, I chose to paint the buffers with a brush as the final stage of painting, masking these seemed an impossible task and fine brush work produced great results.

The FR decals in the set are applied by rubbing onto the cars, they differ from other decals that are applied with water. The decals provided had alignment marks to make positioning easy, my burnishing tool was an artists’ burnishing bone, but a soft tipped lead pencil should work fine.

After decals are applied a final coat of clear lacquer is sprayed on to protect the finish and decals. And reassembly follows as the last step.

Notes on airbrushing: I purchased an Iwata Neo airbrush with an Iwata braided hose for just over $100. Several airbrush air compressors were available from the store I purchased the airbrush from with prices ranging in the $220-$300 range, I chose to use a Porter Cable pancake compressor I use for air tools. A fitting is available to connect the braided airbrush hose to this type of compressor for a few bucks. The only difference between an air tool compressor and a specialty airbrush compressor is one of noise, the airbrush compressor is very quiet while hearing protection is required with the pancake compressor. PSI (pressure per square inch) is a determined by testing on a piece of paper, I set the compressor gauge to 20 PSI which worked perfectly, others I researched recommend 15-20 PSI. Air brushes require cleaning after painting, cleaners are available or water can be used for acrylic paints. When the spray is clear the nozzle is clean, other parts should be cleaned as well. A cleaner between paint colors is also required.

Notes on paint: the consistency of paint should be the same as skim milk, most paints may require thinning with water to gain this consistency. I used Testors acrylic paints that I mixed to customize the color, they are railroad based colors that did not require any thinning. The clear coat I used is made by Iwata, it was the consistency of white glue and required thinning to spray. Acrylic paints dry quickly and can be layered on layer without skinning as can be the case with enamels or the combination of the two. The very best results will be achieved with 100% acrylic paints. Careful attention should be applied in mixing paints for airbrushing, straining maybe required to avoid clogs and poor paint results. For safety use a mask and gloves.

Notes on applying decals: as with much detail work careful consideration applies to attaching decals, they are transferred from a sheet to the model with burnishing tools. Best results are achieved with a level flat object, I use a specialty artists’ burnishing bone. Pointy tools will not work! Acrylic paints should be allowed to dry overnight to provide a hard surface for decal work. And very delicate handling until final spray coat of lacquer. I used clear lacquer with a satin finish which is consistent with Marklin’s coach finishes.

For close to two years I had the decal set and a second Marklin 8135 for this project, but I was reluctant to start due to lack of expertise. Plus I was apprehensive to strip the paint of mint Marklin coaches: after stripping there was no going back. I discovered that air brushing is easier than I thought producing a superior paint finish. Now I feel the airbrush is as important to the railroader as the soldering iron. Future uses for this new tool include weathering track, cars and locos.

Good luck and have fun!

Siding: FR’s Ra 987 electric locomotive is a compatible loco for this coach set, it is based on the prototype from the mid 1950’s:  FR 46.132.01 was produced in a limited series of 32 total, it is still available from quality-toys-trains on Ebay.

 

Rewiring Marklin 8871 and 88711: ICE trains go fast!

Marklin’s 1990’s releases of the TEE 8873 and ICE trains 8871 and 88711 suffer from a design flaw: poor electrical connections caused by the couplers and a train set wired in parallel. Similar to those old Christmas lights when one bulb went they all did, these Marklin train sets suffered a similar fate that was corrected with the further releases of the TEE variations. The ICE train sets changed in another way instead of having two powered units as did the 8871 and 88711 the 88712 and 88714 included one powered unit located in the middle of the train this being a coach.

A simple solution to to correct the poor performance of the three TEE and ICE trains is to bypass two diodes located on each circuit board of the powered units. There are four diodes located on each circuit board, two affect the lights (LED’s) and two are near the motor. Bypassing the diodes near the motor with a soldered wire is all that is needed to allow the locomotive to move forward and reverse thus allowing each powered unit to work without the former wiring constraints.

Note: no need to bypass the diodes on any other TEE train version released after 8873.

Note: 30 gauge wire is recommended for wiring circuit board, tinning the ends of wires is recommended before making the soldered connections.

The early ICE trains use an interesting light bulb with a red and a clear bulb soldered to a circuit board similar to the traditional mini-club bulb. The red bulb is hooded to direct the light better, but unlike the LED’s the light is rather dim unless the loco is cranking! Note: very fragile bulb and no longer available, but if you are good at soldering you can make your own.

The couplers as mentioned are faulty for electrical connectivity, but work great when both powered units are rewired: coach lights no longer flicker. The couplers for the two ICE trains are susceptible to damage due to the untethered ends of the copper strips, great care should be taken to prevent bending. A good recommendation is to stock up on parts as they become available on Ebay. The original couplers for the 8873 are infinitely more resilient than the couplers used on the first two ICE trains.

Note: save old loco light bulbs that don’t work, new ones can be easily made by using the original circuit board for soldering news bulbs to them, generic bulbs are available at train shops in the correct size.

Siding: the 5 pole motor replacement for the 8871 + 88711 is 211907 which is one of the more expensive motors for upgrade, and you will need two. I have not made the upgrade to 5 pole with my sets, the original 3 pole motors work exceptionally well at low speed and throughout the range, but the 5 pole motors would be much quieter.

Siding: removing the tight fitting shells from 8871 and 88711 is more easily accomplished with synthetic guitar picks of .70 mm thickness or thinner.

Soldering Irons: 2 choices for small works

Honing one’s skill with soldering is gained over time and the right tools help.

The most important tool is the soldering iron, many good ones are on the market so deciding which one feels good in your hand trumps every recommendation I will hence forth make. Working with mini-club due to small scale and plastics require delicate operation so one cannot stress the importance of an iron that is comfortable, but two irons that I want to share have been newly introduced to me that are very good and both made by Weller.

The first iron is part of a kit, it is sold with a base station that includes a holder and sponge, but it also regulates the output if the iron is plugged into it. It comes with a standard flat tip, but numerous tips are available including pencil tips which I like for circuit board soldering. This kit sells without solder for $45 on Ebay with free shipping. Features solid construction and multiple heat settings: Weller SPG 40.

The second iron is battery operated, it works with 4 batteries and reaches full output in 30 seconds. Weller claims it will do hundreds of soldered joints with one set of batteries, when it stops melting solder it is time for a new change of batteries. It is a really nice iron for easy cordless operation and lightweight handling plus includes a work light. The standard tip is a pencil tip, the kit also includes a clip to hold it between solders, solder, and batteries. This is $20 at Sears Hardware. One difficulty with this iron is the rather tenacious grip of the battery holder clips, it is required to press the sides of the battery holder to slide the compartment out which is not easy. The solder also includes a plastic cap to keep the tip clean during storage, I recommend removing the batteries between uses in case the switch is turned on thereby possibly creating a fire hazard! Two settings on the power button include low and high temp, I found low temp worked perfectly for soldering fine solder and 30 gauge wire: Weller Light Duty 6-8 watts cordless battery operated iron.

Siding: flux core solder is the recommended due to its ease of use, it does not require a separate flux.

Repainting Marklin 8135 coaches for the SJ: Part 2

Part 2 is completed: stripping the old and prepping for the new. Marklin’s 8135 Dompfeil set is the subject of the repaint and older SJ coaches will be the end result.

I am using the FR label kit for the repaint which includes dry transfer lettering, lettering will take place in Part 4.

Following Part 1 which was disassembly this post concerns stripping paint from plastic train shells. The stripper is 91% isopropyl alcohol available from any drugstore, its cost for this project $4.00.

I first placed all parts to be stripped (4 coach shells and 1 roof panel) in a small plastic dish and submerged them in the alcohol. In about 1 hour the paint appeared to be softening on the shells. Using a toothbrush I applied little pressure to remove the paint and decals, it would take numerous attempts with time in between to remove the finish, but it eventually started coming off with the toothbrush. The roof which was yellow in the original set was much more difficult to strip, it required an overnight soak in the alcohol. The silver painted roof panels I did not strip these I will simply spray over, I stripped the warm white panel due to the thickness of the paint which was heavier than the silver paint.

Note: use of eyewear and gloves is highly recommended. The fumes from the alcohol is very strong thus a well ventilated work area is best, take frequent breaks to avoid breathing in too many fumes, the plastic parts are not affected by the alcohol, they will not melt.

For paint that was in small crevices or around roof details I made use of a toothpick, soaked in alcohol, it worked well to dislodge hard to get at paint.

Following the stripping I washed each part in mild Dawn dish washing liquid and rinsed well.

After inspecting each dry part I repeated the stripping to remove paint on some of the window frames.

photo: after

The next step is painting which will include constructing a spray booth out of cardboard box, matching paint chip FR included in kit, and constructing armature to hold the parts for painting.

Siding: the Dompfeil coaches are the same ones made in Germany for the SJ, they featured aluminum roof panels: early ones were painted gray and the late ones were shiny silver. For these coaches I am modeling the earlier ones to be pulled by an Ra 987 Express locomotive.

Tinning: the soldering practice briefly explained

Tinning is simply the soldering of stranded wire to make solid wire, but many railroaders are not aware of this practice and its benefits.

Why tin? Soldering the ends of stranded wire eliminates the fraying of stranded wire which can become a nuisance over time when the wires leading from the feeder track have to be stripped for the transformer posts. Also this type of wire is easier to cut to length for intricate repair work. It is not recommended for Marklin plugs because it can be brittle and break when screwed into these connections, Marklin wire makes a better connection with these plugs.

Before soldering a connection it is recommended practice to tin the ends of stranded wire to make soldering easier.

Siding: mini-club wiring of circuit boards can be a touchy exercise, tinning the ends of wires to be used and cut to just enough length will shorten the time the circuit board is subjected to soldering.

 

 

 

VT 11.5 TEE Railcar: Improving Performance

Improving performance can be a bit of a misnomer when the talk circles around modifying a Marklin Z loco or other article in the mini-club line-up. Upgrading 3 pole motors to 5 pole motors is a significant boost to performance, but other improvements may deserve further research and discussion with other railroaders and their experiences.

One improvement I have heard about for many years is actually one I heartily suggest, Glenn and Sandy Stiska of Florida rewired several sets for me in the late 1990’s with this same repair. The modification I am talking about is the addition of two wires to each powered end unit of the VT 11.5 (8873) and the 2 ICE trains including the special release “Amtrak.” For many years this modification has been used with multi-train sets with more than one powered unit. Wired in parallel these early sets were poor runners because they relied on something close to perfection, if the electrical chain was broken between head loco, coaches and end unit the train would not go.

The 8873 used an early conductive coupling which connected the coaches to the powered end units that has since been redesigned: all railcars now use a new flat conductive coupling versus the early spring copper one.

photo: 8873 powered end unit with first generation coupler on left and 88731 Max Liebermann with next generation coupler on right

The original wiring included a pair of diodes for each circuit board which dropped the voltage to each powered car and only allowed each powered unit to go in one direction a contributing factor for stalling the train and/or flickering coach lights if power was interrupted which it readily did. The solution is to bypass the diodes by soldering a wire around each diode thus making it possible for each powered end unit to go in both directions.

A fine point soldering iron is recommended for the repair and just enough wire because too much would interfere with installing the shell.

Try this repair if you have a set of this type that does not run well, the results will blow you away!

Six versions have thus far been released with the last being the “Blue Star Train” with its very striking paint scheme.

Siding: removing the shell of the 8873 is accomplished by removing coupler if it is present and carefully inserting a small screwdriver in the coupler box, if the shell does not easily pop up it maybe stuck to chassis due to hardened oil which will require finessing to unseat it from the chassis, removing the shell from all other VT 11.5’s will require lifting the front of the shell and wriggling it around the permanent coupler. Caution: do not pull on a permanent coupler, it is not removable unless circuit board is removed first.

 

 

Customizing and Repairing: Rotary Snowplow Train Set

I recently purchased a customized 81361 Rotary Snowplow trainset, this being the first customized Marklin Z in my collection. I would not have bought it if I knew it was a used set, it was described as new. My impulse to buy outweighed good judgment, but it turned out well. The silver lining was how nice the customizing was, it was carried out by someone with knowledge and love of trains. And the former owner applied a great deal of precision in the work they did.

Precision is the word best applied to working in the “Z Scale World”, much of what we do in this small scale requires planning, patience and skill sets unique to the hobby. My best tools for working on the railroad are tweezers and magnifying goggles which I am wearing right now!

Another silver lining aside from the excellent look and operation of this train set is learning something new, in this case wiring and weathering a rotary snowplow train set.

Modification: in order to improve power pick-up to the motor the tender’s wheels are used in combination with the loco’s driving wheels to receive electricity from the tracks. This is accomplished by soldering two wires to the leads and running those wires to pick-ups that connect to the tender’s wheels. Word of caution with this modification: tender pick-ups have to make good contact with the wheels without preventing them from turning. This modification also requires exposing two wires from the loco cab to the tender, for some this maybe distracting. And this modification may not even be deemed necessary by most otherwise Marklin would have built it into the original design.

Weathering: not so much weathering but bringing out the texture of the cutting wheel. Carbide cutting blades are used to cut through large snow drifts in the prototype, in this model a dry brush with silver paint was used to highlight this part of the cutting wheel. Great care is required accomplishing this feat, but the result is interesting. If you are new to dry brush practice first on something inconsequential before taking on this project. And don’t forget magnifying lenses either in goggles or desk top magnifier.

Repair: the materials Marklin uses for the trains is the best available and correctly chosen, in this model the plastic hinges and couplers can over time require adjustment. To tighten a hinge on the snowplow doors simply remove the door and with careful handing of tweezers gently pull the hinge sides closer together, they get loosened up over time, but the plastic is flexible enough to allow very gentle pressure to tighten. The unique coupler that attaches snowplow tender to steam loco is another example of the aforementioned, apply gentle pressure with your fingers to reduce the size of the coupler end thereby making a tight connection with the loco. Without a tight connection between snowplow tender and loco the train will uncouple.

Maintaining your collection is part of the fun of owning it, and we all become better in time. And it is a good time to better understand the workings of our trains.
