  2. 2-8-8-8-4 - Wikipedia

    en.wikipedia.org/wiki/2-8-8-8-4

    Only one 2-8-8-8-4 was ever built, a Mallet-type for the Virginian Railway in 1916. [1] Built by Baldwin Locomotive Works, it became the only example of their class XA, so named due to the experimental nature of the locomotive. Like the same railroad's large articulated electrics and the Erie Railroad 2-8-8-8-2s, it was nicknamed "Triplex".

    The Northern Pacific Railway was the first railroad to order a 2-8-8-4. The first was built in 1928 by American Locomotive Company; at the time, it was the largest locomotive ever built. It had the largest firebox ever applied to a steam locomotive, some 182 square feet (16.9 m 2) in area, to burn Rosebud coal, a cheap low-quality coal. But the ...

    Between 1951 and 1956, 78 Class D60 2-8-4 locomotives were rebuilt from Class D50 at the JNR's Hamamatsu, Nagano and Tsuchizaki Works. In 1959 and 1960, six Class D61 2-8-4 locomotives were rebuilt from Class D51 at the JNR's Hamamatsu and Kōriyama Works. Some of these locomotives survived in service up to the end of steam traction on the JNR ...

    en.wikipedia.org/wiki/Tractive_effort

    Possibly the highest tractive effort ever claimed was for the Virginian Railway's 2-8-8-8-4 triplex locomotive, which in simple expansion mode had a calculated starting T.E. of 199,560 lbf (887.7 kN)—but the boiler could not produce enough steam to haul at speeds over 5 mph (8 km/h). Of more successful steam locomotives, those with the ...

    In 1930, the C&O ordered the first of forty 2-10-4 "Texas"-types from Lima, which they classified as the T-1 class, and they shared identical design features with the Erie’s 2-8-4s. [ 1 ] The T-1s were equipped with a trailing truck booster that exerted 15,275 pounds-force (67.95 kN) of tractive effort.

    The North Eastern Railway Class S3, classified B16 by the LNER, was a class of 4-6-0 steam locomotive designed for mixed traffic work. It was designed by Vincent Raven and introduced in 1920. The earlier members of this class were fitted with Westinghouse Brakes - all of this equipment was removed during the 1930s.
