Hi friends,

I've seen a lot of conversions of the Soviet 2-unit diesel locomotive TE7 from Atlas Minitrains ("Transsibirische Eisenbahn"). Honestly, no one satisfied me (sorry :)), so I'd like to show how this Atlas train set should be motorized, lighted and digitized :) I made this conversion about 2 year ago.

Chassis

I know that it's hard to find a suitable chassis for this train set. It's hard, but it isn't impossible. TE7 is a 2-unit 12-axle locomotive, so it need 2 6-axle chassis. Some use for this BR 103/151 chassis, but it's not the best solution because this chassis is too long. Pivot-to-pivot and axle-to-axle distance is also too long, and TE7 looks, for me, very bad on this chassis. Usage of a shorter 4-axle BR 110/BR 143 chassis is also not a good idea because axle count for TE7 in this case is incorrect.

I've found a solution that is closest to prototype - to use BR 143 chassis with installed 3-axle bogies from Ludmilla (Marklin 88132, 88133 etc.). It's a more expensive option because you have to buy spare parts from Ludmilla, but the result is worth it, because you get a prototypical motorized TE7 in the end. To be precise, 3-axle Ludmilla bogies are slightly shorter than TE7 bogies, and there's a small misalignment of the outer axles, but it's almost invisible on completely assembled locomotive.

Couplers

I milled out central part of the plow to make space for couplers. It is possible to install both types of couplers - Marklin and MTL (US style). Despite that Marklin couplers are standard option for Z scale users in Europe, MTL couplers are much more prototypical for Soviet train models:

https://en.wikipedia.org/wiki/SA3_coupler

Additionally, MTL couplers allow to connect locomotive units and wagons very closely, closer than with Marklin couplers. USSR train models are very few in Z scale and produced only by a private small series manufacturers (including me), so MTL couplers is an "unofficial" standard for Soviet models in Z scale.

Lighting

Headlights and taillights is a very important option of any locomotive model. It's not so easy to equip TE7 with lighting, but I have found a perfect solution for this too. I made 1 mm holes for lower headlights, and 1,5 mm for upper light. It was quite tricky to drill a hole for last one, I had to drill diagonally. Then I cut small pieces of fiber optic and glued them to SMD LEDs with wired outputs using cyanoacrylic glue. I used 0402 LED for upper light, and unique bi-color 0805 LED's for lower lights (warm white/red). Front side and the roof of the cabin was painted in black from the inner side. I even modeled a cabin interior (however it's hard to see it on the photos).

Digital

I used 2x VELMO LDS206247-I decoders. One decoder per one unit. I soldered out flexible metal contacts from decoders and soldered light outputs directly to the decoder's PCB's.

Baggage car

I replaced original non-rotating bogies with ones from Marklin IV-V era passenger cars. They are very close to Soviet bogies for passenger cars. Marklin couples were replaced with MTL. Additionally I painted triple tail lights with red paint and door handles with silver.

Please see attached pictures. TE7 train set is depicted here in combination with our USSR standard passenger car.
