I picked up the replacement frame today for the Bachmann Consolidation.
And it was indeed the correct part that I was looking for.
My thanks goes out to the fine soul in the Bachmann parts department who made a small effort for me and got what I needed.
So the engine is now back together.
I'm actually quite pleased to have this unit back in the roster. Once it's programmed and I get the work train built it'll be a nice variation from the F-7s.
Zamac poisoning indeed!
