TANK
DOUBLE-ENDED "SUBURBAN" TANK ENGINES
2-6-6T and 4-6-6T TYPES
In 1906 the Boston & Albany received ten 2-6-6T locomotives built by Schenectady followed by eight more in 1907 designated Class L-1a and L-1b. The tank engines had 20x24 inch cylinders, 63 inch drivers and operated off 185 lbs. of boiler pressure. During 1928-1931 Lima rebuilt the engines with superheaters, increased the cylinder bore to 23 inches and the boiler pressure to 200 lbs. The rebuilding produced a substantially more powerful engine. The rebuilt locomotives became Class L-3 and L-3a and when 4-8-2's were delivered in 1940 as that class, they were reclassified D-2a and D-2b.
