I was fascinated by the July edition covering the history of
railroads in south-central Colorado. Otto Perry's 1952 photograph taken
of a Rio Grande passenger train clearly shows the dual gauge used in
the Salida yards to accommodate both standard and narrow gauge trains.
Colorado was lucky in that it had to contend with only two gauges.
Granted, there was an extensive two-foot tram system in the Central
City-Black Hawk area, but it did not complicate matters in other parts
of the state.
