4-8-2 MOUNTAIN TYPE

The Bangor & Aroostook owned ten 4-8-2 type locomotives numbered 100-109 and five purchased from the New York, Ontario & Western numbered 120-124. All were built by ALCO Schenectady.

CLASS M - consisted of numbers 100-103 built in 1929, 104-106 built in 1930, 107-108 built in 1935 and 109 built in 1945. They had 22 1/2 x 30 inch cylinders, 63 inch drivers and operated off 240 lbs. of steam. At starting they produced somewhat more tractive force than the most powerful BAR 2-8-0s but the 2-8-0s with tender boosters produced just about as much starting tractive force as the 4-8-2s with boosters. Nevertheless, the large boilers and fireboxes on the 4-8-2s resulted in more horsepower.

THERE WAS LITTLE DIFFERENCE BETWEEN THE M CLASS 4-8-2s BUILT IN 1929 AND 1935

AS SEEN IN THE BUILDER'S PORTRAITS OF NUMBERS 100 AND 108.

109 is at Northern Maine Jct. in November 1946.

CLASS M-1 - consisted of five locomotives numbered 120-124 acquired from the New York, Ontario & Western in June 1945. All were built in 1929 to essentially the same plans as the New York Central's L-2-d 4-8-2s.

They had 69 inch drivers and were substantially more powerful than the BAR M Class. Nevertheless, the M-1 4-8-2s were all scrapped by 1949 while the M Class was whole in 1950 and five engines lasted until 1953.

121 is at Derby in November 1946.
