This is a film of a really fine 3 rail 0 Gauge layout of the MILW in the Cascades in Washington State, taken just before the layout was taken down, pending a move.
This is some of the finest modeling that I have ever seen.
The electric locomotives, including some “Little Joes,” all are powered from live catenary.
