#2-10-2

(thanks for sending @4449fandom ...very interesting! No, I don't know where that turntable is, either.)

Emerging in 1962, the rebuilt 45401, now renumbered No. 25, emerged as a powerful 2-10-2T meant for Banking and Heavy Freight, althought they can be often be found on excursion trains during the summer rush.

CB&Q 2-10-2 Class M-3 6305 by Chuck Zeiler Via Flickr: Chicago Burlington & Quincy Railroad 2-10-2 Class M-3 6305, date, location, and photographwer unknown, print by Tom Klinger, Chuck Zeiler collection. Number 6305 was built in 1919 by Brooks Works (Alco, c/n 59823), and sold for scrap in August 1953. The CB&Q Locomotive Assignment Sheet dated February 1, 1952 indicates that 6305 was leased to the Colorado & Southern Railway, so this was likely shot in Colorado circa 1950.

CB&Q 2-10-2 Class M-3 6309 by Chuck Zeiler Via Flickr: Chicago Burlington & Quincy Railroad 2-10-2 Class M-3 6309, date, location, and photographer unknown, print by Tom Klinger, Chuck Zeiler collection. Number 6309 was built by the Brooks Works (Alco) in 1919 (c/n 59827) and sold for scrap in August 1953. The CB&Q Locomotive Assignment Sheet dated February 1, 1952 indicated that 6309 was leased to the Colorado & Southern Railway, so my best guess is the date is sometime around 1950 and the location is somewhere in Colorado.

CB&Q 2-10-2 Class M-3 6306 by Chuck Zeiler Via Flickr: Chicago Burlington & Quincy Railroad 2-10-2 Class M-3 6306 at Dunkirk, New York, on an unknown day in 1919, photograph by the Brooks Works of the American Locomotive Company (Alco), print by Alco Historic Photos, Chuck Zeiler collection. Number 6306 was built by Alco in 1919 (c/n 59824) and retired in August 1953. The following is from the book, 'Steam Locomotives Of The Burlington Route', by Bernard G. Corbin and Richard F. Kerka: The Class M-3, 2-10-2 types were built by the Brooks Works in 1919, and followed the USRA standards for locomotive design. Their general appearance and construction details were similar to the O-4 Mikados, except that Southern valve gear was employed. The M-3 engines were assigned to the road as No. 6300-6309. They operated on a boiler pressure of 190 psi, weighed in at 293,000 pounds on drivers, and exerted a tractive force of 73,800 pounds. Their cylinder dimensions (30X32) were identical the the class M-2 and M-2a engines. The M-3 locomotives saw most of their service on Colorado and Southern tracks, as they were leased to this subsidiary by the parent Burlington. All of the engines were equipped with Worthington feedwater heaters except No. 6303 and 6308, which were fitted with Elesco systems. During Word War One the production of locomotives was taken over by the United States Railroad Administration amid much controversy by the railroads. The goal was to rationalize production and conserve materials. Although the war lasted from 1914 to 1918, the actual USRA production began in mid-1918, four months from the end of the war. The reason for the U.S. on the tender was that locomotives were built in batches under USRA design specifications, then allocated to railroads based on need. Of the 175 USRA Heavy 2-10-2's built between 1918 and 1920 (end of USRA's reign), ten were allocated to the CB&Q. Since the builder had no way of knowing which railroad would receive the locomotives built or which tender would go with which locomotive, all 175 received U.S. on the tenders, and upon allocation by the USRA, were finished with road name and number before delivery, as seen in the photograph.
