Four Rio Grande FT diesels labor up the Front Range of the Rockies with a 55-car freight out of Denver in March 1942. Smoke from the train’s 2-8-2 pusher is visible in the distance. This line up to and though Moffatt Tunnel was built by the Denver & Salt Lake but used heavily by Rio Grande trains on trackage rights before D&RGW acquired the D&SL in 1947.
