| Chicago Burlington & Quincy Railroad 4-6-2 Class S-3 2960 on Train #9 at Sand Creek, Colorado on June 11, 1939, photograph by Jackson Thode, Chuck Zeiler collection. I'm hoping that Larkspur is close to Sand Creek, which is how the print is marked. Number 2960 was built by Baldwin in 1915 (c/n 42160) and sold for scrap in July 1952. At some point it acquired a Worthington feedwater heater, it wasn't delivered with one. Fifteen Class S-3 Pacific types were built by Baldwin in 1915 (road #'s 2950-2964) and an additional ten were built in 1918 (road #'s 2965-2974). Additionally, in 1922 two more S-3 design locomotives were built for the FW&DC (road #'s 556-557) and three for the C&S (road #'s 373-375, class F-3C). The C&S also acquired (around 1936) CB&Q 2970, 2973, and 2965, becoming C&S 370, 371, and 372 respectively, classed F-3B. The three Class F-3C locomotives built for the C&S had 69 inch drivers (as opposed to the 74 inch drivers on the CB&Q locomotives), which were better suited to C&S grades and resulted in a tractive force increase from the stock 42,400 lb. to 44,000 lb.. . |
