Cog railways can travel up steep hills and mountains because of an extra rail underneath with teeth. Cogwheels on the train itself fit into those teeth and keep it pushing upward. Some of these railways have been in service over a hundred years in the Alps and the Rockies! Take a closer look at how they work and see some spectacular photographs at Dark Roasted Blend. Link
