The 1100-04 series mail-baggage cars were ordered for the 1947 Empire Builder, with the GN owning 1100-03 and the CB&Q the 1104 (until 1953). With the arrival of the ACF mail-baggage cars (37-42) for the Mid-Century Empire Builder in 1950, the 1947 cars operated in a pool with the Western Star and the Winnipeg Limited. These cars are very similar to GN 1105-07, which were ordered for the Internationals and Red River Streamliner.
This set of sides matches cars with full side skirts; the unskirted versions are available separately as item #173-563.
These sides are designed for use with the various American Limited Models Passenger Car Core Kits (#147-8010 - 8040) sold separately and with instructions.
