D&RGW Railroad History

The Marshall Pass Route was the Denver & Rio Grande railroad’s original narrow gauge mainline through the Rocky Mountains westward.

When William Marshall first crossed the pass, he realized that it would be a good route for a road, and shortly after this, a company was organized to build a toll road.

  • The Marshall Pass Toll Road was completed in 1878, with stagecoach service from Gunnison to the Arkansas River where it connected with the Denver and Rio Grande Western Railroad.
  • The new road at the pass summit was barely passable, and the grades on both sides of the pass were reported to be very steep.
  • Today Marshall Pass road is around a 4% grade most of the way

  • The Marshall Pass line was a narrow-gauge, with rails just three feet apart.
  • Which allowed for a tighter turning radius in the switchbacks climbing the over the high mountain passes but meant smaller cars and smaller freight loads.

Scenic Line of the World

  • Construction on the railroad started from Salida in the middle of September 1880, and soon reached Poncha Springs.
  • The line roughly followed an old toll road that had been laid out by Otto Mears and purchased by the Rio Grande to facilitate construction.
