  1. 2-8-8-8-4

    Under the Whyte notation for the classification of steam locomotives, a 2-8-8-8-4 has two leading wheels, three sets of eight driving wheels, and four trailing wheels. Other equivalent classifications are: UIC classification: 1DDD2 French classification: 140+040+042 Turkish classification: 45+44+46 Swiss classification: 4/5+4/4+4/6 The equivalent UIC classification is to be refined to D for these engines. Only one 2-8-8-8-4 was ever built, a Mallet-type for the Virginian Railway in 1916. 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". An overview of Triplex engineering is given at Triplex. The XA was unable to sustain a speed greater than five miles an hour, since the six cylinders could easily consume more steam than the boiler could produce. The tender had a four-wheel truck at the rear to help guide the locomotive into curves when drifting back downhill after pushing a train over the hill.
