This is my long term (REALLY long term) project. I have gone so far as to:
1) Get donor shells can be suitably kitbashed (MTH EP 5s), You can see the similarities...and the differences. The primary one being the EP5 is much shorter and less massive). With the MTH units I'll get the right sounds (close enough) and the nifty panograph movement.
2) Running gear (Sunset F units),
3) The truck sides made in resin, then cast in brass. Work done by Russ Briggs
4) the 48" wheels using the Sunset axles. Wheels machined by Carl Jackson
Stay tuned.
