I'm curious if anyone knows the answer to this.
I was told recently that EMD sized the Blomberg B trucks such that only EMD traction motors would fit in them in an effort to make it harder to switch to another manufacturer.
Is this true? And if it is true, how did those railroads that used Blomberg Bs under their Uboats accomplish that? I assume they still used GE traction motors.
Further, I've been given to understand that MPI/MK actually stretched the Blomberg M-2 (leaf spring) to match the AAR truck size and offers it as an option on their locos. What is the purpose of that?
I remember the old member Boagie engineer saying that the Outside swinghanger Blomberg and was far to complex a design for modern apps and needed to be replaced. I had thought that they were no longer being made, but apparently MPI is having them made.
Can anyone illuminate?
