Midland Terminal 2-8-0 "Consolidation" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 29-1 (Locobase 7698)

Data from CC&CS 1912 Locomotive DiagramRaildata collection supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also Schenectady Locomotive Works, Illustrated Catalogue of Simple and Compound Locomotives (Philadelphia: J B Lippincott, 1897), pp. 130-131. Works numbers were 4427-4431 in April 1896, 4741 in May, and 5178 in 1899.

This septet of Consolidations started out with the Midland Terminal Railway when that line was built in 1893-1894 to connect the larger Colorado Midland Railroad to Cripple Creek. (The line actually ran from Divide through Midland and Gillette to Cripple Creek.) The Schenectady Catalogue noted that the class was operating "..four per cent. grades and sixteen degree curves."

By the mid-19 teens, the MT had concluded a lease with the recently reformulated Cripple Creek & Colorado Springs Railroad, which published the data shown in the specs. The CC&CS pulled together several folded lines such as the Golden Circle, itself a successor to the failed narrow-gauge Florence & Cripple Creek (F & CC), and the standard-gauge Colorado Southern & Cripple Creek Division electric railway which covered all of 6 1/4 miles. (The C&S had leased the CS&CCD to the F&CC in 1915.)

Anyway, the CS & CCD went bankrupt in 1919 while the Midland Terminal operated until 1949. This class remained on the MT all that time, being scrapped as the road closed down in 1948-1949.
