Here are the Y1/FF2 Electrics. I admit I am using the designations from memory . . .
The one on the left is Sunset - they did a superb job, except for only powering four axles. Takes two of them to haul six of my Empire Builder cars. The one on the right was cobbled together using castings from Stevenson Preservation Models. How he finds the time to produce small production runs of such varied models baffles me - but it is a great thing for that part of the hobby that likes to build stuff.
