In the Whyte notation for describing steam locomotive wheel arrangement, a 2-8-6 is a locomotive with a two-wheel leading truck, eight driving wheels, and a six-wheel trailing truck. All 2-8-6 locomotives constructed have been Mason Bogie tank locomotives .
[2] [5] [6]: 211–212 [3]: 26 Air pump / Air compressor Westinghouse pump (US+) Powered by steam, it compresses air for operating the train air brake system. [3]: 2 The Westinghouse air brake system is used world-wide; [3]: 93 in Europe two systems that use the same principle are the Kunze-Knorr and Oerlikon systems. It can be a single-stage ...

Triplex locomotives are locomotives with three drive wheel sets. The Baldwin Locomotive Works built three 2-8-8-8-2 triplex locomotives for the Erie Railroad and one 2-8-8-8-4 for the Virginian Railway. All the triplex locomotives built were of the Mallet type, but with an extra set of driving wheels under the tender.
While economical at speed, the locomotive was highly-uneconomical at lower speed. The turbine used less steam than conventional locomotives above 30 mph (48 km/h), but below that the locomotive used too much steam and fuel. The boiler normally operated at 310 psi (2.1 MPa), but at low speed the pressure could drop as low as 85 psi (0.59 MPa).
Two classes of 2-6-6-6 locomotives were built: the sixty H-8 "Allegheny" class locomotives for the Chesapeake and Ohio Railway (C&O) between 1941 and 1948, [1] and the eight AG "Blue Ridge" class locomotives for the Virginian Railway in 1945. [2] (The locomotives were Series AG on the Virginian. This was an abbreviation for "Articulated, Series ...
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".
