As it turned out, steam locomotives continued in service for almost another 20 years. Gene Huddleston's book, C&O Power, reports tests of the C&O with a dynamometer car indicating momentary readings of 7,498 hp (5.6 MW) with readings between 6,700 to 6,900 hp (5.0 to 5.1 MW) at about 45 mph (72 km/h). The state of calibration of the dynamometer ...
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. [1]: 80 It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times.
The Union Pacific Big Boy is a type of simple articulated 4-8-8-4 steam locomotive manufactured by the American Locomotive Company (ALCO) between 1941 and 1944 and operated by the Union Pacific Railroad in revenue service until 1962.
Coupled with an elegant French style tender, the second batch of the 240P class was aesthetically much more pleasing. With a power output of 4,700 horsepower (3,500 kilowatts), the 240P class was reputed to have the highest power-to-weight ratio of any steam locomotive. Discussion continues as to how robust they were mechanically, for example ...
Atchison, Topeka and Santa Fe 2926 is a class "2900" 4-8-4 type steam locomotive built in May 1944 by the Baldwin Locomotive Works for the Atchison, Topeka & Santa Fe Railway (ATSF). It was used to pull passenger and fast freight trains, mostly throughout New Mexico, until retired from service in 1953. In 1956, ATSF donated no. 2926 to the City ...
These were the largest and fastest steam passenger locomotives to run in Japan. [25] Between 1953 and 1961, 47 Class C60 locomotives were rebuilt from surplus Class C59 4-6-2 Pacific locomotives at the Hamamatsu and Kōriyama factories.
