EDIT: This is what the kit was intended to look like:
End of EDIT
The railcars will run anywhere on my layout, except the HOn30 mine track.
The sound will come from the railcar itself. The car has a large box on the back to haul cargo, similar to a shortened freight car but smaller in height and width. There will be ample space for a decoder, speaker, capacitor and enough weight to maintain decent contact with the rails. It is no different than a sound decoder installation in an engine.
Power pick up will be challenging because there are only two driving wheels. However I have worked out a means of picking up power from the front truck which has four wheels despite their tiny size. The railcar will need to be as heavy as possible.
I will post pictures after I have made some decent progress. Right now I only have the basic frame and front and rear suspensions assembled. I am researching how to put the Model T sounds into a decoder. It is quite doable but it requires a full range of engine sounds and that is my current stumbling block. You can follow my progress on a separate thread that is specifically related to putting sounds on to a decoder.

If I can’t get the necessary sounds then the railcars will be built with six cylinder engines. Loksound will be offering a Gallopping Goose decoder in the near future which uses a six cylinder Buick engine. The front hood assembly will be taken from a Jordan school bus so the whole thing will end up being larger than if it was built with a Model T engine.
