This feature shows the mightiest steam engines on the Denver and Rio Grande system in all their glory. These giants are shown tackling the steepest grades on the railroad: Moffat Tunnel line, Soldier Summit, Tennessee Pass. Drag freights slog up mountains with three articulated engines pushing and pulling. Passenger trains strain to keep up speed in the high Rockies. We see these monsters charging along the “joint line” south of Denver, crossing the desert west of Grand Junction, and diving into the depths of the Royal Gorge. Runaways, landslides, and boiler explosions are covered. The feature begins with a ride on the daily passenger train over La Veta Pass to Alamosa at the height of the glory days of steam. We ride the train from the sun-drenched Cuchara Valley into a driving blizzard at the top of the pass, and back down into crystal-clear weather at the foot of the breath-taking Blanca Peaks, in an era long gone but not forgotten.
