Chicago, Burlington & Quincy Mountains

In 1922, the Chicago, Burlington & Quincy Railroad's passenger trains needed heavier power and it ordered and received eight 4-8-2s (road numbers 7000 through 7007) from the Lima Locomotive Works. These Class B-1 "Mountains" had 27 x 30 cylinders, 74" driver, a boiler pressure of 200 psi, a tractive effort of 50,240 lbs and a weight of 364,000 pounds. All eight were designed to burn lignite.

The Baldwin Locomotive Works delivered thirteen Class B-1a "Mountains" in 1925. These locomotives were assigned road numbers 7008 through 7020 and were similar to the Class B-1s. Seven were designed to burn lignite and the other six were equipped to burn bituminous coal.

By 1953, all of the Class B-1s and most of the B-1a locomotives were scrapped. The last Class B-1a was scrapped in 1955.
