This TV movie featured some scenes on the Durango & Western Narrow Gauge RR. 

Title shots show Durango & Silverton's D&RGW #473 pulling a passenger train over the High Line over the Animas River canyon. This engine is one of several that still operate on this route today. 

We see some more scenic shots of the train passing over various landmarks along the route. 

D&RGW Coach #291 "King Mine" from 1881 is featured in the Silverton depot scene. This car is also still in use at Durango & Silverton. 

A western town set was built somewhere along the river for the final scene of the film.
