A total of 26 of this Bo-Bo type were built between 1966 and 1968.
"The C415 was equipped with a raised cab mounted slightly off-center, with a lower, narrower hood on either side. The longer one contained the diesel engine, a 1,500 hp (1.1 MW) eight-cylinder turbocharged Alco 251-F, while the shorter contained auxiliaries. The C415 could be ordered with three different cab heights; a low one for minimum clearances, a regular height one, and an extra-height one for maximum visibility."
"Trucks fitted were either Type B road trucks or ALCo Hi-Ad (high adhesion)."
