I was discussing the postwar B&M commuter coach fleet with a friend the other day. I mentioned seeing in several videos PRR P-54s, Lackawanna Boontons, and Reading coaches, all painted maroon. When were these steel cars acquired? My friend says some the P-54s were sold off by PRR in the late '30s. I thought the steel cars came postwar, similar to the situation where the P-RSL was told by the NJ state Public Utilities Commission to replace the wooden MU equipment.
