Scale: Z

A mountain layout that winds up the mountain with a side branch.
Operationally it is intended to be run with very little stock and small
engines. In accordance with mountain railway practice the design assumes the
locomotive is always at the lowest end of the train.

This requires some thin woodwork and severe grades but with one or two
trucks/4 wheel coaches only you can get away with it. Would probably work
better in N with the Fleischmann rack loco.
