The ALCO 251 prime mover was the most popular and abundant prime mover ever made by the company. While it proved to be quite successful, it sadly outlived its original manufacturer, ALCO who closed their doors in 1969. The 251 prime mover is actually still available to purchase today from Fairbanks Morse for use in Marine, Generator, and locomotive uses.

The 1000 horsepower 6cyl version of the 251C could be found in the following locomotives:

MLW S-13
MLW RS-23

Almost identical sounding 6cyl 251, 251A, 251B, and 251D were found in the following locomotives:
S-5
S-6
T-6
DL535E
DL535EW
NSWR 48 Class

As with all SELECT decoders there are up to 16 separate horns, 2 separate brake squeals and 2 bells included on this one sound profile! All changeable using CV48.
