Bangor & Aroostook 2-6-0 "Mogul" Type Locomotives

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.

These Moguls (works #1647-1650 - December 1895 & January 1896) have relatively tall drivers and were probably mixed traffic engines. In 1915, three were converted to 4-4-0s (see 5995).
