Reply to "Permanent Magnet Open Frame Motor"

There is no upgrade path for the great bulk of pre- and postwar steam having the "parallel plate" type motor.

What would be the upgrade path for a parallel plate motor? It seems to me that any upgrade would require the separation of the two parallel plates to get to the field. It's no easy task to separate and rejoin those plates.
I think your mention of an entire replacement chassis would be the way to go.

IMHO, some of the old modern era locomotives that used that postwar style parallel plate motor mechanisms would benefit from a replacement chassis. In my experience, they don't run as well as the postwar ones.

I had a pre-1950 2025 running on my layout today. Still runs very smoothly and quietly on very little power.
