Revised 7/16/05
Bob Chaparro reports: "For 1951 I have the following cars, by type, assigned to this service:
4-4-2
Castleton Bridge
4-4-2 George Washington Bridge
10-6 Chicago River
10-6
Chateaugay River
4-4-2 Thousand Islands Bridge
4-4-2 Tri-Boro Bridge
4-4-2
Brooklyn Bridge
4-4-2 International Bridge
4-4-2 Rip Van Winkle Bridge
4-4-2
High Bridge
4-4-2 Imperial Chariot
4-4-2 Imperial Crown
4-4-2 Imperial
Empire
Apparently, the last four cars on this list were only occasionally
assigned to this service.
4-4-2 Sleeper:
NYC 4-4-2 Imperial series (Imperial Domain, Imperial Empire, and possibly others) from New York via Chicago to LA. These cars were re-named in the 1948-49 to the Bridge series. Eastern Car Works kit 1206 is correct for the 4-4-2 sleeper of NYC. Brass Car Sides 173-16 and Laser Horizons 3P442 are the pre-war P-S 4-4-2 Plan 4069 smooth side Imperial series. In 2003 Walthers came out with these cars ready to run.

Santa Fe All the Way Vol. 1, p. 36, shows
the ATSF switching in NYC Pullman Tri-Boro Bridge in Chicago, 1954. It
will end up on The Chief.
10-6 Sleeper: NYC 10-5 Cascade series from New York via Chicago to LA were added in 1949. These are available from Brass Car Sides and Laser Horizons.
These were soon replace by 10-6 River Cars (Chicopee River, Indian River, Kankakee River). No models are yet available for the Plan 4123, but a variety of 10-6 cars, including the RTR Rivarossi (AHM) smooth side 10-6 sleeper can substituted.
Both the NYC and PRR cars were two-tone gray smoothside cars. Originally the two roads' paint schemes were very similar, but in 1948 the NYC reversed its scheme to a dark gray carbody with a light gray window stripe, and also changed the shades of gray. There's excellent information on this, including the Central cars, in Pennsylvania RR Passenger Car Painting and Lettering by Blardone and Tilp, published by the PRR Historical & Technical Society.
Michael Flick wrote in the Santa Fe Modeler, March/April 1981, issue, wrote:"During the time that the cars operated via the Chief, cars of the connecting railroads, and Santa Fe cars were freely interchanged in this service.
A July 9, 1951 Pullman Company listing of car assignments for the New York Central showed the following cars assigned to transcontinental service: 4-4-2 sleeper; New York Central cars Castleton Bridge and George Washington Bridge; and Santa Fe cars Nava, Bacobi, Saydatoh, Tsankawi, and Seboyeta; 10-6 sleeper, New York Central cars Chicago River and Chateaugay River, and Santa Fe Cars Pine Bell, Pine Beach, Pine Brook, Pine Cavern, and Pine Arroyo.
On July 26,1951, the following New York Central cars were substituted for the Santa Fe 4-4-2 sleepers: Thousand Islands Bridge, Tri-Boro Bridge, Brooklyn Bridge, International Bridge, and Rip Van Winkle Bridge. The Santa Fe car Nava was listed as an extra. Other New York Central 4-4-2 sleepers known to have operated in this service were High Bridge, Imperial Chariot, Imperial Crown, and Imperial Empire."
