This is a classic shot of restored locomotive 315,originally built in 1895.  It sat in a park in Durango, CO for 50 or so years after it was retired and lovingly restored by a group of volunteers over a period of several years.  It does not run often but when it does it attracts large crowds of enthusiastic fans to see it run.  This particular shot was on a charter in the fall of 2013.  This is narrow gauge steam at its best!
