ALCO251 Air Start

The Alco 251 diesel engine was developed by the American Locomotive Company to replace the 244 and 539. The 251 Prime mover was Alco’s best selling prime mover. In 1954, the 251 went into production with the inline-6 at Auburn, New York. Ultimately a refined and successful design, the 251 outlived its designer. For a time it was built in Canada by Montreal Locomotive Works. Today it is still available from Fairbanks-Morse. Examples of the 16-Cyl 251 can be found in the following locomotives:
Air Start Examples: C430, C630, C636,C630M, and Some M630s and M636's
Electric Start Examples: RS-27, RSD-15, RSD-17, C424, M424W, C425, C628, C855, C855B, M630, C636, M636, LRC-2, LRC-3 and HR616.
