Built in 1953 for the United States Air Force,
#4040, a BLH RS-4-TC, was among some of
the last locomotives ever built at Baldwin's
Eddystone, PA shops. After serving overseas,
(primarily in Morocco), #4040 was brought
back stateside, rebuilt with updated internals
at the Tooele (UT) Army Depot, and assigned
to Selfridge Air Base. There, 4040 transported
inbound coal trains received from the Grand
Trunk Western to the base's coal-fired power
plant. After rail service was discontinued in
the mid-1990's, Selfridge donated the
locomotive to the MTM, where it still operates
today in regular passenger service.
