Note the D&RG engine (narrow gauge) which was switched over from Cucharras street as a work train and heavy snow removal. Street car tracks were made in the same gauge as the Denver and Rio Grande Railroad.

Notice that the commercial buildings on the right, south side of Colorado Avenue are of poorer construction than the north side. That was where the Saloons, and Gambling Dens fronted the Avenue. One block further south along Cucharras where the train to/from Manitou ran, was the Red Light District. One block North on Pikes Peak Avenue was Church Row - a church on every corner - who battled the Saloons and voted dry in 1913, killing the original Colorado City.

The few famed Tunnels from the North side to the South Side for men to slip across the street unnoticed were discovered as the original streetcar tracks were laid, and had to be filled in else the tracks would sag. None still exist completely across the street.
