D&RGW (Denver and Rio Grande Western or simply Rio Grande) Narrow Gauge Steam Locomotives are narrow gauge steam locomotives manufactured by various locomotive builders such as Baldwin.
D&RGW K-36

A K-36 narrow-gauge steam locomotive.

They varied in size, with the large K-37 being a modified standard gauge steam locomotives built on a narrow gauge frame.

About 75% of the Baldwin-built locomotives are preserved.


They were built from the 1860's to the 1950's, and were discontinued due to the End of the Steam Era and the D&RGW's full transition to standard gauge in the 1960's.
