Pullman cars assigned to the Pennsylvania Railroad were usually shopped at the Wilmington, Delaware repair facility. The UP-SP-C&NW San Francisco Overland pooled sleepers with the Pennsylvania Railroad for New York City-San Francisco trans-continental service through the city of Chicago during this period and these cars, especially the 10-6 Rapids series cars, probably were shuttled into and out of that train to the shops.

  10 roomette-6 doublebedroom Stoney Rapids was delivered by Pullman and placed in service in December 1948. It and Tippecanoe Rapids were the two cars PRR contributed to a New York - Los Angeles transcontinental pool with the Union Pacific, which added five Pacific series 10-6's. This Pullman line was operated on the Admiral on the PRR and the Los Angeles Limited on the UP/C&NW. The PRR cars were painted the standard PRR tuscan red until 1955 when the transcontinental line was moved to the UP City of Los Angeles. At that time both cars (Tippecanoe Rapids 4/29/55, Stoney Rapids 6/9/55) were repainted into the UP Streamliners scheme of Armour yellow and Harbormist gray but still lettered Pennsylvania on the letterboard. On October 30, 1955 to routing between Chicago and Omaha was changed from C&NW to the Milwaukee Road. Fall of 1956 the service was changed to every other day, and Tippecanoe Rapids was removed from the pool and repainted PRR colors. Transcontinental service ended October 26, 1956, but Stoney Rapids was not repaint to PRR colors until July of 1958.

  All cars were in for general shopping. Records show that Salix (4/11/51) and Rowland (9/16/52) were repainted in PRR tuscan. Carville was sand blasted so was probably repainted also.
