The image is digitally retouched. Notes for operation: This locomotive can be used on curved track with a radius of 261.8 mm / 10-5/16" or larger, but we recommend larger radius curves. Due to the overhang of the long boiler, signals, catenary masts, bridge railings, tunnel portals, etc. must be mounted to provide sufficient clearance on curves. The track must be well mounted for the high weight of the locomotive. The turntable and transfer table can be traversed by the locomotive but not turned or moved.
