Pacific series (railcar)

The Pacific series was a fleet of fifty lightweight streamlined sleeping cars that the Budd Company built for the Union Pacific Railroad in 1949 and 1950. Each car held ten roomettes and six double bedrooms, the layout railroad people called the 10-6 sleeper, of which 682 were made in the United States after the Second World War. All fifty were built on Budd lot number 9660.039 to Pullman Plan 9522, and unusually for Union Pacific equipment their sides were corrugated rather than smooth. Budd delivered them between December 1949 and June 1950, making this the largest class of sleepers on the Union Pacific. One car, Pacific Empire, was written off in a 1951 collision at Wyuta, Wyoming. The Union Pacific sold five to the Milwaukee Road in 1969, and Amtrak bought 43 of the remaining cars between 1971 and 1974. Most were retired in the mid-1990s, some became crew dormitory cars, and several survive as business cars.
