>>1440976>didn't MILW's FP45s not have dynamics? When you go back to the 1980's, 1970's, and especially the 1960's, many diesel locomotives did not have Dynamic brakes.
In today's world it's rare to not have them. 40 years ago it was about half and half. MILW's passenger trains didn't usually encounter serious hills (TC Hiawatha route is pretty damn flat) and were so equipped.
