Separating East from West
Among the engineering marvels of the Western Extension were these: the many substations that dotted the Rocky Mountain division in Montana and Idaho and then the Coast Division in Washington. Here the old mainline climbs and curves its way to the crest of the Belt Mountains with the outline of the Substation at Loweth looming on the horizon. Mountains separated this country's east from the west, and the Resourceful Railroad crossed the first of them here.
The grade to the top is as grueling today as it was decades ago: 1.4%. How easy it is to imagine boxcabs lugging hard at the compound curve as they work their way westbound.
