Battery Powered Locomotive from 1929? YES Behnke!

A locomotive that will surely garner attention on a Z layout is this small battery powered locomotive and trailer based on the prototype from 1929: Behnke release “1929 AKKUTRIEBWAGEN Muller.

Built by G. Muller in 1929 the locomotive appears to have been used for MOW service and yard work. Standing room only in the cabin this was a no frills work a day probably every day workhorse.

I sprayed the completed model in a dark red brown, followed by an inky black to top structures and finished with dry brush in a very dark gray to accentuate the details of the trucks and platforms. Headlamps are rendered in bright white paint with very fine brush.

Note: Behnke kits do not provide couplers, wheel sets or buffers, this model is awaiting buffers from FR available later in 2018.

Group Effort: introducing E 69 electric Z-Modellbau

Faller and Marklin will help me introduce the superb Z-Modellbau E 69 02 “Pauline”  electric locomotive for DB (article #2101).

The prototype was built in variations starting in 1905 culminating in 1930. A beautiful model of the prototype never offered in Z except by Z-Modellbau.

I will be posting some interesting research on electric locos coming in the future but for now many photos and not many words.

 

Handrails and add-on parts bring great detail to this loco that is not surpassed by any manufacturer.

Metal construction with brass gearing and brushless motor are standard features of Z-Modellbau.

Z-Modellbau locomotives are delivered in a small blue box lined with foam and small instruction sheet noting this locomotive is maintenance free and should not be taken apart.

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.

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.

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.

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.

SBB CFF FFS class Ce 6/8 III: Marklin’s new release 88563!

The iconic articulated Swiss loco “Krokodil” has long been associated with Marklin in all their scale models, but the new 88563 is a further development of this Era II loco in technological terms for ‘Z’ collectors following numerous releases of this loco in special editions and other variants since the first 8856 (green paint scheme) serie Be 6/8 in 1979 and the 8852 (brown paint scheme) serie Ce 6/8 in 1983.

For the first time changeover headlamps/trailing lamp in LED. Plus partially new tooling including the incorporation of catenary switch below the hood as it were and the removal of the roof top screw formally used to switch power on the circuit board from track to catenary. Removing the catenary screw from electric locos has been a continuing design function of the new locos just as improved running gear and side rods on the steam engines, it is a good time to get into the Marklin mini-club hobby!

Photo: 88563 (top chassis and bottom hood) and 8856.4 (green loco chassis and its hood showing hole through roof to support catenary screw)

A brief look under the hood between the new release and an older 8856 variant is a new circuit board supporting wires for the LED changeover lights thereby obscuring the motor, as can be seen in the photo the circuit board is solid and does not support engagement with brushes, this new motor is identified on the parts sheet as E279 138. Is this a new generation motor? A quick google search revealed nothing!?! When I have more time I will be taking this one apart and reporting what I find! Note: runs great out of the box!

Photo: Marklin 88563 (top) and 8856.4 (version 4: 2009-2010)

Note: switching to catenary power is achieved by carefully pushing the slider switch on the circuit board, in earlier versions this switch was a slotted head that extended through the roof of electric locos.

Follow-up: The new 88563 reveals a new generation motor! I couldn’t wait to find the time to conveniently take apart 88563 to reveal its workings so first thing this morning I opened it up. On first inspection of the circuit board I missed noticing the black and tan leads soldered to the circuit board which descend through holes in the board to the motor, which sits in a newly designed chassis. As with all 8856 variants the articulated locomotive design is comprised of three parts including mid section containing motor with two worm drives and front and rear driving wheel sets, in this new locomotive the mid section chassis is newly designed and dispenses with circuit board clips as well as any visual access to the motor. The circuit board is further redesigned in function but also appearance with two retaining screws and a much thinner board.

Future repair: Any future repairs to this locomotive will be difficult for any but the more advanced modeler. Due to its thin construction the circuit board will be prone to cracking and replacing the motor will be a skilled operation requiring un-soldering of points on the circuit board. How often are future repairs expected on Marklin Z in general? ZERO in my experience except for the cleaning of gears and motor upgrades of the traditional 3 pole/ 5 pole variety.

Closing: Thru advancements in technology and detailing closer to the prototype Marklin is producing some truly outstanding trains, but more intricate parts and complex wiring schemes could be seen as challenges to overcome on the workbench.

Siding: If you have an SBB Krokodil that runs rough perhaps after cleaning and reassembling it maybe due to the front and back side rods being out of alignment. If the loco runs well in one direction but rough in the other reassemble side rods so they are high on one end and low on the other.

 

SJ Ra 987 Electric Locomotive

Out of the pages of the commemorative 100 year anniversary book of the SJ is a gleaming new Ra 987 with its operators.

The Ra 987 express electric locomotive was introduced in the mid 1950’s and manufactured by ASEA with the final production of the locomotive ceasing in 1961. All 10 locomotives reportedly are still in existence as preserved museum locomotives, but before retirement these locomotives pulled express trains for nearly 30 years on two routes: Stockholm-Goteborg and Stockholm-Oslo. Ra trains consisted of characteristic SJ brown paint scheme express coaches similar to the German coaches in the 8135 “Dompfeil” set, a repaint of that set will give you a good express train set for your SJ railroad.

Similarities in appearance between the American F7 and the Ra of the SJ is not coincidental the F7 was the designers inspiration for the Ra. Two paint schemes for the Ra existed the early one is featured here, but the later one featured a broad white strip with the word “RAPID” on its nose. The later version included a variation of the headlamps. Two snowplow designs included a broad cage across the beam of the locomotive and a second one featured on the FR 46.132.01 incorporates to plows each side with a filigree cage centered between the plows.

A powerful can motor operates the locomotive along with LED powered headlamps as is standard equipment in all FR locomotives. The FR exclusive equipment includes an ingenious design for the locomotive coupler comprising an ‘L’ shaped wire thus allowing for the installation of intricately designed snowplows, this coupler system works flawlessly with Marklin Z standard couplers.

Note: the 1st version of the Ra produced by FR is long of production, but the 2nd version is planned as a production model at FR. To order the 2nd version a preorder commitment must be made with FR, it won’t be available after it is released, FR does not seem to make extras for some of their releases others seem to become regular production models.

Produced by FR in a very limited edition of 32 worldwide is the Ra 987 electric locomotive for SJ.

Siding: The MY locomotive of the DSB and its various amalgams on other railroads although diesel powered is similar in appearance to the Ra with a similar type American F7 “Bulldog Nose” plus two cab ends.

FR’s Prototypical SBB Pantograph: Installation and Description

The new pantograph for Marklin’s Ae 6/6 electric locomotives is prototypically accurate and replaces the original pantograph with a few modifications. FR of Germany has produced this very interesting and important upgrade part that is better made than the Marklin original plus it looks great! The new FR SBB pantograph is available as part number 41.190.00, each is delivered in a hard plastic case.

A side by side comparison of the Marklin original and the new FR pantograph reveals a larger pantograph with a heavier spring. The solid construction of the FR eliminates the sometimes drift seen in the Marklin pantograph. The Marklin pantograph is a bit generic as well coming in just a few variations in color otherwise the same is used on German and Swiss locos. The FR upgrade will add zip to your locomotives for Swiss railroading with striking silver finish true to the prototype.

FR pantograph on left and Marklin on the right:

Installation gets easier after the first one due to familiarity with the small parts and coordinating the assembly after modifications are made. As discussed in earlier posts assembly includes modifying the shell by removing the original plastic parts on either side of pantograph, I simply pulled them off with my fingers taking care not to damage the wires on the shell’s roof. The heat points for the original parts will provide the holes for the new FR pantograph, but first the 4 silver caps/washers need to placed around these holes, the legs of the new FR pantograph are thus placed through the washers and holes. This step can be a little tricky so take your time and work over a workbench to catch the parts if they go astray. Final step is applying pressure to the pantograph and securing with included screw. At this point the pantograph is attached, but you might notice looseness of the legs and washers of the new part, in this case I applied a very small drop of 5 minute epoxy to each hole on the interior side of shell. *NEVER USE PLASTIC CEMENT ON MARKLIN LOCOS DUE TO MELTING FROM THE SOLVENTS IN THESE CEMENTS, 5 MINUTE EPOXY IS THE ONLY RECOMMENDED GLUE FOR MARKLIN Z.  A pin will ensure a small drop versus too much glue seeping out of shell. Careful with this step, but I recommend it to marry the new parts to the shell in permanent correct orientation!

“Cargo” locomotive pictured with the original Marklin pantograph and roof equipment and Ae 6/6 locomotive features the new FR pantograph:

This highly recommended upgrade for Swiss Ae 6/6 locomotives will cost about $60 for 2 pantographs or 1 loco delivered to USA collectors, it is only available directly from FR. Photos show completed locomotives with the new FR pantograph.

Ordering from FR is fast and easy with an excellent website, careful packing and fast shipping. FR’s website uses green signals to indicate in stock items otherwise date projections for out of stock items, locos are seldom available at any given time, but they can be reserved for next production run usually 6 months out, worth the wait!

Note: FR lists the new pantograph can be used to upgrade the Re 4/4 locos, Marklin has released three thus far, but as of this posting I am not sure how the upgrade is made. I will be posting an update after speaking with Harald Freudenreich on this matter.

 

2nd Report on the new SBB pantograph: FR 41.490.00

I just received the new FR pantograph for Swiss locomotive types: Ae 6/6 and Re 4/4II, and I immediately installed it on the Marklin 8849 Serie Ae 6/6 electric locomotive; it is even better than I could have expected!

Installation of this part on one of the appropriate Marklin Z locos is a restoration project so to speak, for the first time the correct pantograph can be installed on Swiss locos which originally but incorrectly included the same style pantograph used on German locos. Until now Marklin has offered three styles of pantograph design with variations for a total of 6 different pantographs; they are all installed with a single center screw and furnished with electrical roof equipment of various cast plastic parts.

The FR pantograph is installed with a single center screw of the same diameter as the Marklin one, but simple modifications must be performed including the removal of plastic parts on each side of the original pantograph. If you want to preserve the plastic removal parts simple cut the melt points on the inside of shell: DO NOT USE A SOLDERING IRON TO REMELT THESE POINTS, USE OF AN SOLDERING IRON IN THIS MANNER WILL MORE THAN LIKELY RESULT IN PERMANENTLY DAMAGING THE SHELL BY MELTING IT. I simply pulled these parts off because I had no intention of saving them, each broke into many small pieces.

The pantograph is delivered in a nice plastic box with the screw installed in the pantograph, and a part sheet is included that contains the 4 post caps that are used in the installation. To upgrade one loco you need to buy a pair (2) of these pantographs (FR part #41.490.00). Cost to replace one pair of loco pantographs with the new FR ones is $56 including shipping for USA buyers. No directions are needed or included, but I will provide a few notes:

-First: remove shell from loco and unscrew the pantograph from inside shell

-Second: remove plastic parts from each side of original pantograph mounting on shell

-Third: working over a workbench preferably foam use tweezers to break apart 4 small post caps (part is located below foam insert in plastic box

Fourth: very small post caps are installed over the holes on shell that plastic parts (now removed) were originally engaged with, pantograph legs are inserted through the openings in the post caps, these small parts are precision made but due to their size they are somewhat difficult to work with, I installed the post caps over each of the four holes in alignment with the legs some wriggling of parts occurred before all four legs met up with the post cap holes, place pressure on pantograph top, tip upside down line-up screw in hole and tighten *you will find your own way during installation, use care to not lose parts and perhaps work over a parts collection tray working with one pantograph at a time

Several important advances have been made in Z-scaling including the advent of the 5 pole motor, side rod detailing, can motors and now a new pantograph for two Swiss class locos!

The following Marklin locos can be upgraded to the prototype with this new part: 8829 (Ae 6/6 released 1994-1996), 8849 (Ae 6/6 released 1987-1993), 8850 (Ae 6/6 released 1984-1987), 88501 (Ae 6/6 released 2003-2008), 88591 (Re 4/4II released 2012), 81410 (Ae 610 released 2010), and 81413 (Ae 6/6 released 1998-1999).
