Across Marias Pass (DVD Video) Stretched against the sunning backdrop of Glacier National Park, Burlington Northern’s transcontinental mainline climbs up and over the rugged Rocky Mountains. One scenic splendor after another unfolds as long freight trains struggle up the mountain pass. It’s the pre-merger days of the early 1990s and Pentrex is trackside to record the battle of trains and nature. The grandeur of the mountains is almost overwhelming as we explore the line from Whitefish, Montana to points east of Browning. You’ll see trains snake their way through the tunnels and along the banks of the wild middle fork of the Flathead River. Train after train rumbles through forests of aspen and larch decked out in glorious fall colors or struggles against winter’s storms. After crossing over the high bridges and through the famous snow sheds, the trains work hard up the pass to crest the summit. Marias Pass takes on a different look on the east slope. Wild, desolate country with ever-present mountains marks the high plateau. You’ll see trains cross over Two Medicine Bridge and struggle upgrade through Grizzley. The solitude of Spotted Robe is broken as you watch a heavy grain train grind its way up the grade. Burlington Northern and Mother Natures combine to make this stretch of railroad a place to be visited time and time again. No matter how often you’ve been here before, you won’t want to miss this vision of magnificent Marias Pass.
