Bangor & Aroostook 2-6-0 "Mogul" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class A (Locobase 5996)

Data out of 1923 BAR locomotive diagram book provided in April 2004 and 1938 BAR diagram book provided in May 2005, both from Allen Stanley's extension collection. Works numbers were 1647-1648 in October 1895 and 1649-1650 in January 1896.

These Moguls have relatively tall drivers and were probably mixed traffic engines. In 1915, three were converted to 4-4-0s (see 5995).
