I'm VERY interested!
caught a break today, actually had some time to tinker at the train bench:
made a little progress even.
one thing (trailing truck) is now decided. it will be a ?-8-4t.
as this is a saddle tanker, i will have to pick up one leg of current from somewhere, so, it will have to come from the trailing truck, and possibly the lead truck.
the drivers will supply the other leg.
