While its competitors dispatched passenger trains behind fleets of E-units, Santa Fe preferred F-units geared for passenger-train speeds. The exceptions were a handful of E3s and E6s and a dozen E8ms, all rebuilt in 1953 from pioneering E1s. Assigned to service on the San Diegans, most wound up on short runs in Texas, Oklahoma, and Colorado. Here mid-morning June 16, 1964, E8Am 83 waits with a baggage car, coach and sleeper at the Amarillo station for a connection with the westbound San Francisco Chief. Then she’ll take train 93 down the line to Lubbock, returning late in the afternoon as train 94.
