Fictional Baldwin 10-12-D style loco for TU-Koppel chassis. Apparently Baldwin's loco naming sceme would have classified this as an A 6-12-C. She has space in the boiler to fill with weights. It is might be possible (although a bit of a stretch) that this thing could have been built as a trench railway shunting loco or something. (for me I'm going to use one as a stand in for a Baldwin 10-12-D)
