After the Consolidations of the classes 56 and 60, the D&RG received twelve larger class 70 locomotives in 1881. They were used, among other things, as helpers on a four percent steep incline. Five locomotives were converted to standard gauge in the late 1890s and later reverted to three feet. When the D&RGW was reorganized they became the Class C-19 because they now had a starting tractive effort of about 19,000 pounds thanks to new boilers rated at 160 psi. The locomotives originally numbered 400 and 409 still exist today after more than 140 years and can be seen in service on the Ghost Town & Calico Railroad on Knott's Berry Farm in California.
