I’ve always wondered what prototype (if any) Lionel used as the basis for the 2400 series passenfer cars - they certainly don’t look like anything that would have come from Budd or Pullman Standard. I was going through an old Model Railroader (July, 1996) and found an article on a “Pennsylvania RR 10-6 Sleeping Car,” by George Sebastian-Coleman regarding a series of cars bulit by ACF for the PRR for a joint service with the Missouri-Pacific on the “Eagle.”
The cars were built were built with “riveted sides with belt rails both above and below the windows,” and have the same vent on the roof above the doors as the 2400’s. The big changes were the reduced length of the car and that the roofs on the 2400’s are much flatter and don’t have the riveted seams. I wonder why they picked such an obscure car to model?
For some reason, I feel better now about weathering and repainting them.
