I have developed an interest in the PRR mp54 cars hauled by steamers. I have read about combines and seen photos of mail/passenger commuter cars. My question is did these consists ever include the heavyweight 6 wheel trucked headend cars, such as BM70s and/or B70s? I read a post on another forum (site misplaced) that referred to a rule/directive that the p54 cars should not be placed between heavy steel cars or between the locomotive and a heavy steel car. Any thoughts?
Wouldn't this rule apply with the simple fact that the p54's were lightweight ping pong cars with the lighter trucks. There would be a concern with the heavyweights behind them, especially in a derailment, this would according the m54's given there lightweight.
When I pull our dinner train I feel the heavyweight shove on every hill, I barely notice the P54D's back there. The heavyweight is the first car in the consist.
