While doing some research on the Denver Public Library online photo collection I came across this interesting photo of Hecla Junction. This is where the narrow gauge Calumet branch left the mainline. The photo date is given between "1890-1910?" and the photographer is unknown:
Hecla Junction
The photo is looking southwest. The Rio Grande mainline is on the right and the Calumet branch curves past the water tank to the left. The branch was known for grades of 7%. The branch was abandoned in 1901 after it was devastated by a flash flood, but was not removed until 1923.
Several items to note:
1) the mainline still has third rail for 3 foot equipment.
2) the water tank was built far away from the mainline, but next to the branch line so that both could be served by it. A long trestle structure brings the stand pipe out to the mainline water spout.
3) the branch line is not connected to the mainline and looks like the switch was recently removed. From aerial photos it appears as if a wye was located here as well.
4) The remaining branch line track appears to be standard gauge, with no third rail evident. Maybe the wye was dual gauge at one point and the third rail has already been removed.
5) there is a boy on horseback down by the bridge.
6) a really nifty sign announces this is Hecla Junction...
