HOn30 GE 25-Ton Locomotive
This is a picture of an HOn30 General Electric 25-ton locomotive. The project was made using a Grandt Line HOn3 GE 25-ton loco, with the wheels slid in a bit to get HOn30 gauge. This is done by carefully trimming some of the "shoulder" off either side of the gear on the axles. The disk-shaped copper object is a US penny (7.5 mm diameter).
