Modifying BTTB to use as North American Proto

Modifying BTTB to use as North American Proto

Postby AstroGoat760 » Wed Feb 14, 2018 11:42 pm

I know that it has been discussed before, but here is a video showing the progress on the conversion of a pair of BTTB class 107 Diesels to look more like North American proto:

I will be making more videos on showing how I did what I have done thus far in the near future.

This locomotive (German BR107/V75, Czech T.435.0 / class 720, Soviet ChME2) looks very similar to the GE U6B locomotive. (or maybe U5B, but U5Bs were mostly narrow gauge ones).
But check the trucks. There were two different types of trucks, you should better use the old ones, "Pennsylvanian type" - they are close to the American ones.

Most of the U6Bs and U5Bs were sold to South and Central America, Asia and Africa, but there were some demonstrators in the USA, and also one U6B served on the Lancaster & Chester Railway for several months.

But suddenly I've discovered this photo:

Georgetown Loop Railroad - General Electric 52-ton U6B


Description:
This is a 52-ton, end-cab, narrow-gauge, road-style switcher engine on display at the Colorado Railroad Museum in Golden, Colorado, USA. It was built in 1956 by General Electric and used in Plaster City, California as U.S. Gypsum # 1403 (http://www.rrpicturearchives.net/showPi ... id=2384121). From 1992 to 2004, the unit was used by the Georgetown Loop Railroad in Colorado as # 140. The engine was acquired by the museum in 2004.

The engine model is a General Electric 52-ton U6B, but it is slightly different from true U6B units. It has been jokingly referred to as a "U5.9B".

The "GB&L" lettering on the cab below the roster number stands for the Georgetown, Breckenridge & Leadville Railroad.

So I think you can find a good prototype for your models. :)

Also notice this nice layout:

It was built in the 1990s by Michael Klostereit, Berlin, Germany. It is "Costa RIca". Notice the diesel locomotive.

From S.E.S. Modelltec is an item named TT-Basteltuete (TT-craft bag), in which mostly is a BR107 shell.

I should have such a shell in my parts stock.

How bad out of place would a modified BTTB BR107 look painted as a Soo Line engine?

I am considering making one or two as my third (and possibly fourth) BR 107 refit for North American operations, as they run pretty well, and are easy to work on, and look close enough to NA proto for my tastes.

Here is an idea that I came up with today:

Using a modified Nohab diesel as a stand in for the Baldwin DRX6-4-2000.

Would the BTTB BR107 have a sufficiently modern motor to be convertible to DCC?

You can convert anything to DCC. Or just by a newer Tillig 107.

I believe so, but don't hold me to that. The main issue is the lack of free space inside of the shell, with how large the weight is.

I have read that there are issues with older motors with high current draw and a risk of blowing the decoder. Or maybe you just have to buy the right type of decoder.

Considering that it is possible to use a DC-60 motor with DCC (if prepped right), anything is possible, with enough effort in TT scale.
