@Jtrain posted:I thought that the B&O through sleeper was cancelled by GGD. Or are you referring to a sleeper with MP lettering running on the B&O?
Yes. The GGD B&O car was canceled. However, MP lettered 14-4s ran on the National Limited from St. Louis Union Station to Washington DC. If you are interested, Texas Special / MKT and Frisco 14-4s did too and a Frisco Meteor 14-4 went past DC to Jersey City, NJ. (Reference / Baltimore & Ohio Passenger Service, 1945-1971 Vol 1 The Route of the National Limited / Stegmaier, p. 20) However, These cars did eventually disappear as rail travel slowly died.
