EMD NW2s

I have a question about Phase 2 EMD NW2 switchers built in 1945.

Would 567A engines be in Phase 2 EMD NW2 switchers built in 1945? In later rebuilding upgrade programs, could they be upgraded to 567ACs and would they get an increase in horsepower?

Upgrading from an A block to a C block would not increase the horse power. The B and C version of the 567 are incremental improvements in the overall design mainly in the area of maintenance and air flow of the prime mover.
There is also a BC block upgrade that can be done to a B block to bring it up to the same basic platform as a C engine.

Our F-3 b has a B block in it and our two A's have BC engines in them. We currently have a a lead on a working C block that if all goes well, it will end up in the B.

OK. That explains it. I was worried that C components would change the engine characteristics.
