ALCO built a total of 1,418 RS-3 locomotives, 1,265 of which were made for American railroads. The RS-3 was powered by a turbocharged, four-stroke V12 diesel engine and four traction motors.

The Alco RS-3 and its cars remained on the siding and in decent shape until somewhat recently. Thieves and vandals found the train and its condition is quickly deteriorating.
