Has there ever been a P-54 commuter coach model made by a manufacturer? It is a Pennsy suburban coach. The railroad I model, the MA & PA would rent them for specials that they ran occassionally and would be run in their consist pulled by one of their heavy consolidation engines. I have not been able to find this model and am wondering if anything has ever been written about it or if a manufacturer has ever made it. Any help would be greatly appreciated. Thanks ahead of time.
