| Chicago Burlington & Quincy Railroad class B-1-A 7008 at Philadelphia, Pennsylvania on an unknown day in July 1925, photo by Baldwin Locomotive Works, Chuck Zeiler collection. The CB&Q had 21 Mountain-type (4-8-2) locomotives on its roster, the first seven were built by Lima Locomotive Works in 1922. As-delivered, the Limas lacked feedwater heaters (later equipped with Worthington heaters), the trailing truck was a Rushton-type, and the tenders rode on four-wheel pedestal design trucks. The Baldwins were 1800 pounds heavier (possibly due to being built with Worthington feedwater heaters), the trailing trucks were Delta-B types, and the tenders rode on six-wheel Commonwealth trucks. Locomotive 7011 was the only Q 4-8-2 equipped with an Elesco feedwater system. Later, some of the class B-1a were equipped with roller bearings, box-pok wheel centers on the main drivers, and three B-1a's were converted to burn oil. |
