Oooo A T-19.. Going to have a big collection of 3 foot gauge locos at this rate! I wouldn't usually have an interest in diesels but are we going to see any narrow gauge diesels? 45 toners seemed to be pretty widely used.
Photographs are all very nice but what I need for modelling purposes is either some plans or good side and end elevation pictures and some measurements. They, at least, would give better results. Cab interior views are also a problem.
