Marklin 88892: BR 10 Experimental Paint Scheme

A special cast gold BR 10 was released as the 3rd of this loco class in 1997 as item number 88891, in 3 years the 4th BR 10 would be released as 88892. The Era III 88892 was a One Time Series for the MHI Program in an experimental paint scheme, various designs were floated before indecision landed on the black paint scheme represented as 8889. The attractive blue with white pinstripe would have been a stunner in the late 1950’s representing a new loco with “forward progress” suggested by the innovative design, but this and other paint schemes were shelved when a consensus of opinion could not be reached. Model originally delivered in an attractive wood box.

Siding: all BR 10’s are Era III, it was a short lived locomotive type with just two prototypes, Marklin released 5 models of this loco but only one was based on the prototype, the others included a special Marklin cast gold model and 3 experimental paint schemes that were proposals only.

Following the release of the 8888 for the MHI program a second BR 10 (8889) with the same operating number was delivered in the same year: 1994. But unlike the one time release of the 8888 the 8889 would remain in production for 14 years ending its run in 2008. During the long tenure of the 8889 in the mini-club line-up a significant upgrade occurred with all Z locos, in 1999 the 5 pole motor was introduced which has since become standard equipment in all ‘Z’ locos. For collectors of Z here is an example with two variations: one with original 3 pole motor and another with 5 pole motor. Color scheme for 8889 is black with white pinstripe lettered for DB with operating number 10 001.

Siding: for collectors buying BR 10’s today it will be rare to find one directly from a Marklin dealer in new condition, the secondary market is the more viable place to find these locos. Buying tip: be sure the loco includes cap that hides screw on top of shell, this is a very hard part to replace and downgrades the value and appearance.

Marklin 8888: BR 10 Steam Locomotive

The first BR 10 loco was released in 1994 as a One Time Series for the MHI Program: product number 8888. Sporting a very attractive paint scheme the 8888 was delivered in blue and gray with bright red wheel spokes and matching tender trucks. A heavy cast metal shell with operating number 10 001 for the DB. Design and styling seems to scream Era III in the age of streamlining as a emblem of progress and modern aesthetics. The model produced by Marklin is a very good runner with plenty of weight to maximize the pulling potential of 4-5 coaches easily.

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.

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.

 

 

 

Side Rods: Correct alignment to make steam locos go!

Sometimes the repair of a steam loco is necessary thus taking one apart can be cruel and unusual punishment for the uninitiated, but quickly it is realized that repairing a mini-club steam loco is achievable with a few general rules.

When I first got into collecting mini-club I remember a dealer offering repair services for all locos except for steam locos, they are too difficult was this much awarded USA Marklin dealer response. Through the course of my collecting the repair and maintenance of steam locos is part of the fun! When I use the word fun I really mean it, what better way than to quietly sit at the workbench on a Saturday afternoon taking apart a loco that does not work and bringing it back to life. The problem solving with a positive resolution is key to excitement of returning a loco to service such is the case with correct assembly of steam locos.

All of us will have a turn removing hardened oil from around the pilot wheel pivot point or wheel set gearing and even the worm gear all requiring a disassembly of the oil pan below the engine. Removing hardened oil is simply achieved but reassembling the steam loco can be the hard part for some locos including ‘mallet’ type or others with more than two pairs of driving wheels. All reassembly of bogies follows the same advice and that is to start at the front drive wheel followed by the intermediate gear followed by the next drive wheel and so forth. The pick-ups that make contact with the drive wheels can be a little tricky but keeping pressure (not too much) to each assembled wheel set in the chain works best otherwise with no pressure the pick-ups would spring outside the wheels. Add side rods to the mix and the assembly gets a little more tricky. Some side rods simply sit in a groove in the cylinder block while other designs allow them to be inserted in slots. The BR 10’s (8888, 8889, 88892, and 88893) side rods are of the latter type, the side rod sits in a groove and the shell holds it in place. Applying pressure to the side rods until the shell is in place adds a layer of complexity to this locomotive type.

Correct orientation of the wheel sets follows that all weighted sides of the wheels are aligned at the same spot to achieve this end one must turn a pair of wheel sets until it aligns. If the wheels are not lined up correctly the loco does not run properly if at all. Inexplicably in the case of the BR 10’s the wheel sets can be out of alignment and still work well on an operating loco, go figure!

Once the loco is taken apart it is a straight forward matter of putting it back together, it will always go back together because Marklin makes them that way. As soon as patience has left the room perhaps one should leave the project to come back to later. Always start from the front of a bogie and leave the pilot and trailing truck for last, they can be slide under the loose oil pan before screwing it together.

Note: before making any such repair organize the work bench with good light and a surface to work on, I use a foam bench made for z by www.z-hightech.de featuring a tool holder, flat area for holding parts, wedge shape section to hold a loco upside down and on angle, and a channel for securely holding the loco in place. This is the very best accessory I have found for train maintenance. I got mine on Ebay from gps_97 under the heading “GPS-5000 maintenance pad”.

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.

 

Under the Hood: Marklin Z Rotary Snowplow

A brief look under the hood of Marklin’s “Rotary Snowplow” in z scale reveals engineering that is both functional and well conceived.

Two worm gears meet up at 90 degrees to turn the cutting wheel that is powered by the 5 pole motor. A heavy metal frame is the foundation for the motor which receives its power directly from the rails without the need of a circuit board, the motor leads are soldered to wires leading to trucks: one wire to each truck soldered to a power pick-ups in the form of spring copper. A unique solution that I haven’t seen in any other mini-club train except for the 3 Rotary Snowplow sets. The overall weight of the snowplow is equal to a locomotive thereby giving it good traction.

To access the interior of the snowplow simply lift off shell, it slides on snugly without clips, I recommend working front and back gently until it lifts off thus allowing the brushes to be replaced: part number 89891.

More than 8 1/2 inches in length the mini-club Rotary Snowplow is an impressive machine.

Take a look at part two of the post featuring customization of the loco and repair notes.

Good Luck and Have Fun!

Marklin Rotary Snowplows: 3 Versions in 1 decade

photo: Denver North West & Pacific Railroad rotary snowplow

The Rotary Snowplow was introduced to the mini-club audience in 2001 with the MHI/Insider release of 81360. An Era III BR 50 steam locomotive and rotary snowplow each included their own tenders thus making the 81360 a German Federal Railroad (DB) maintenance of way train set.

Marklin 81360 snowplow train set

Features of the Rotary Snowplow and loco set includes a separate motor to power the snowplow, it too features hinged tender hatches and a pair of hinged doors for the rotary cutting wheel. Both the loco and snowplow were also installed with the newly designed 5 pole motor which was the standard motor at this time and still is today, but new coreless motors are making their way into new tooled and designed locos more on this at a later time. Coupling the plows tender to the loco is a unique coupler that allows easy uncoupling for storage thus not a permanent coupling. Care needs to be taken to ensure this part does not break, but gentle pressure is all that is needed for this task and the part will live on for many many years.

Rotary snowplows for rail maintenance differ little through history either here in the USA or Europe. A Canadian dentist (J.W.Elliot- 1869) in the 19th century is credited with the idea for the rotary snowplow, up to that time locos pushed wedge shaped plows to clear snow which required multiple locos who’s combined power were needed for heavy snowfalls and drifts. The rotary snowplow cuts through the snow leaving walls on both sides of the track thus limiting the use of wedge shaped plows as an alternative during a winter season. In late 19th century Germany snow removal was performed by wedge shaped plows mounted to heavily ballasted tenders which have been modeled proficiently by Railex in brass.

Railex: K.BAY.STS.B. ballasted tender snowplow

Snow processed by a steam powered rotary snowplow was directed to a vertical chute directly behind the cutting blades which has been successfully modeled by Marklin in their snowplows.

I grew up with a train set in HO, one car I owned was a rotary snow plow that fascinated me, but it was seldom run due to poor performance. The body of the car was satisfactory to a 10 year old but the movement of the cutting wheel was generated by a rubber band linking the cutting wheel to the wheel sets on the car, needless to say it did not work well. Marklin powered their rotary snowplows with their own motors giving this interesting train set authentic appeal. And of course the detailing! Another precision model from Marklin in Z.

So far Marklin has released three Z snowplow and loco sets with variations in railroads and eras, but also tender types, loco types and paint and lettering schemes.
