This was from the Passenger Train topic, but better fits here.
The Pennsy had one 10-6 sleeper that matched the other cars on the CB&Q/D&RGW/WP California Zephyr for through service between San Fransisco and Chicago. The Pennsy took the car between Chicago and NYC. It was the Silver Rapids:
The Penny also had two cars, Imperial Range and Imperial Terrace, that ran on the Golden State from Los Angeles to NYC via Chicago. The GS ended at Chicago and the cars were taken from Chicago to NYC either on the NYC or PRR on alternate days . The Pennsy cars were painted in 1948 to match the other cars on the GS from the CRI&P and SP.
The Silver Rapids is K-Line and the Imperial Terrace is Lionel. The other cars are either GGD or K-Line.
