2-6-6-6

Categories: Locomotive stubs | Locomotives by wheel arrangement

The 2-6-6-6 (in Whyte notation) locomotive type has 2 leading wheels, two sets of six driving wheels and six trailing wheels. The only 2-6-6-6 locomotive type ever built was the "Allegheny" class, built by the Lima Locomotive Works. The name comes from the locomotive's first service with the Chesapeake and Ohio Railway beginning in 1941. The locomotive was so named because of its job: hauling heavy coal trains up and down the Allegheny Mountains.

The equivalent UIC classification is (1'C)C3'.

There are only 2 surviving Alleghenies. One resides in The Henry Ford museum and the other at the B&O Railroad Museum.
