| Chicago Burlington & Quincy Railroad 2-8-2 Class O-3 5330 presumed at Philadelphia, Pennsylvania on an unknown day in June 1917, photograph by Baldwin Locomoive Works, Chuck Zeiler collection. Number 5330 was built by Baldwin in June 1917 (c/n 45756) and sold for scrap in November 1953. The following is from the book, Steam Locomotives Of The Burlington Route, by Bernard G. Corbin and William F. Kerka: The O-3 2-8-2 types were a modification of the O-2 engines. Sixty engines of the O-3 Class were built by Baldwin over the period extending from 1915 to 1919. They were assigned to the road as No. 5300 - 5359. Although the fist fifteen O-3 engines, built in 1915, were equipped with alligator-type crossheads, the subsequent O-3 Mikados were all fitted with those of the Laird type. Accessories on the Class O-3 locomotives, when first built, included a combustion chamber, a brick arch in the firebox, a Schmidt-type superheater, and a Street automatic stoker. In later year the O-3 engines were modified with shorter engine cabs, the single-stage air compressors were replaced with cross-compound tpes, and feedwater heating systems of either the Worthington or Elesco types were applied to many. |
