Christmas Eve, 1945, 6PM. Denver & Rio Grande #346 stops at the station at the top of Tollume Pass in the middle of a snowstorm. Most of the hardy people who live at the top of Tollume Pass are staying warm in the station, but a couple have ventured outside into the freezing cold to meet loved ones who have traveled home for the holidays. In a few minutes, the short train will soon be back on its way heading down the mountain pass.
