Reply to "Headend cars on PRR mp54 commuter train consists?"

I recalled seeing something in Al Staufer's about the 54 series cars.  According to Staufer, the P-54 coach was "the standard suburban coach for steam operation before the Paoli line was electrified in 1915". The photo in Pennsy Power II, shows a P-54 with spoked wheels.   Again, according to Staufer, many of the P-54's were rebuild into MU cars at Altoona.  Addditional cars were built at Altoona and some outside builders (he could not confirm who, but they were build to the same specs).  The total fleet was 819 cars which included "numerious" passenger-baggage cars, full baggage and RPO's.  41 cars were rebuilt as unpowered trailer cars another 227 were build as powered trailer cars semi-permanently coupled with power cars.  It also appears that, over their long life they were rebuild a number of times.
