GN W-1 ELECTRIC.
This is one large electric engine (25.5" not counting couplers).
Like the Y-1 electric, the shell is cast metal.
They did a nice job of painting as those thin yellow strips aren't easy to do (I painted an HO version and they were even smaller!).
GN only had two of these. If I remember correctly, all wheels were powered and it was equivalent to a big boy.
The cab sat so high that, when GN first got them, the crew were ducking when they went through the first tunnel.
When the diesels replaced the electrics, I believe UP took them and used them for one of their turbines.
There's a lot of overhang on the 72" curves.
