The reference for locomotives and railcars

Denver & Rio Grande Western class C-16

originally class 60N

United States 1877 96 produced
No. 220 in 1920 in Embudo, New Mexico Otto Perry / Denver Public Library PD

The Denver & Rio Grande had the class 60N built by Grant and Baldwin as standard freight locomotives starting in 1877. These were Consolidations, which were tiny compared to later locomotives on the three-foot gauge. Baldwin's locomotives had a larger boiler than Grant's. They later received the class designation C-16 from the Denver & Rio Grande Western. Some later received slightly larger wheels and higher boiler pressure. After the new Mikados took over the majority of traffic, the Class 60N was significantly decimated in the 1930s. It could only remain in use where no other locomotives could be used due to the axle load. Today Grant's number 223 remains, having been under restoration for years.
