The C628 replaced the C624 (DL600C/RSD-41) as a part of ALCO's 'Century' line of locomotives. The C624 was intended to replace the earlier RSD-15 model, but was never built. The C628 was offered instead in August 1963.

Hamersley Iron purchased five to haul iron ore services in the Pilbara region of Western Australia. They were built in Schenectady.^[1] All had been retired by 1982, with one preserved on a plinth in Dampier.^[2]

The Southern Pacific purchased the four demonstrators in 1964, and an additional 25 C628s were delivered in 1965.
