The Denver and Rio Grande Western Class M-67 was a class of 4-8-2 "Mountain" steam locomotives with a total of 30 examples built by the American Locomotive Company (ALCO) at their own Brooks Works for the Denver and Rio Grande Western Railroad in 1922.[1][2]
History edit
With 63-inch drivers, they developed 62,661 pounds of tractive force. Cylinder dimensions were 28 x 30 inches, its boiler pressure was 210 psi. They had 4667 square feet of evaporative heating surface and 1333 square feet of superheater surface, plus an 80-square-foot grate area. They had a locomotive weight of 377,000 pounds.[1]
Retirement and disposition edit
They were all retired from revenue service by 1955 and every single one of them were scrapped. Nos. 1511-1520 were modified with a booster engine on their trailing trucks and were re-designated as the class M-78, but they didn't last for very long and they were also scrapped, thus rendering the Class M-67 officially extinct.[1][3]
