I think the most logical place to start is to use an Atlas RS11. You will need to make it a low nose and also shorten the length of it, move the cab forward, and lengthen the long hood using styrene to make up the difference. Then the handrails need to either be modified somehow, or new ones built. There will be a lot of other stuff to do to make it more accurate, but it just depends how far you want to go with it.
Would be a project for sure. But, I feel it is something that could be accomplished with some work.
Chuck - Modeling in HO scale and anything narrow gauge
I've always wanted to have Soo Line's notorious "Dolly Sisters" on my layout. Purchased new from Alco in 1962, they were the very first locomotives on the Soo to sport the new white (actually very light gray) and red scheme with the big "SOO" letters, painted at the factory. They were the Pride of the Soo when they were brand new...They ended up finishing their career in shame, being kept in local service limited to not very far from the Shoreham shops in Minneapolis, as they weren't trusted to venture any further. The name "Dolly Sisters" may have started from the other designation of the RS-27 (DL-630) but was commonly thought of as named such because they were always up on the dolly for repairs. It was somewhat rare to ever see them together as one or the other was usually broke down.
N Scale has apparently utterly ignored this model. How can I create one, short of finding someone on Shapeways to make one from blueprints?
In fairness to the other RS-27's made, Soo's likely became problematic as they were partially made from old FA-1 parts, which had 10+ years on them already.
