During 1965 Alco started producing the 3,000hp Century 630 Locomotive. Produced concurrently with the 2,800 hp. C-628, it incorporated an advanced GE AC traction alternator which provided the extra 200hp. The most distinctive spotting feature of the C-630 is the large aftercooler radiator housing which extends above the roofline (the aftercooler radiators enhanced the performance of the locomotive while operating under a heavy load). The C-630 also featured a modified cab which offered more interior space for the crew. Through the end of production in the late 1960s, a total of 133 units were produced for railroads in the US and Canada.
