I have some questions about two passenger car diagrams in Wayner's "Pennsylvania Railroad Passenger and Freight Car Diagrams"
#1 page 11 has a diagram for a coach-baggage combine, PB70, what are the car number(s) associated with this car?
#2 page 13 has a diagram for a crew dormitory car, PD70R, what are the car number(s) associated with this car, when did this car run and what train(s) did it run on?
