The Madison Incline is the steepest line-haul, standard gauge railroad track in North America. Opened in 1841, the incline has been in existence for nearly 180 years. At 5.89%, this incredible feat of engineering proved to be a challenge for its operators and was last used in 1992.
The Monongahela Incline is a funicular located near the Smithfield Street Bridge in Pittsburgh, Pennsylvania. Designed and built by Prussian-born engineer John Endres in 1870, it is the oldest continuously operating funicular in the United States.
High-speed railways commonly allow 2.5% to 4% because the trains must be strong and have many wheels with power to reach very high speeds. For freight trains, gradients should be as gentle as possible, preferably below 1.5%.
The US city of Pittsburgh in Pennsylvania has two funicular railways, the 1870's Monongahela – the oldest line in operation in the country – and the Duquesne Incline, which is by far the most spectacular one.
The Funicular is older, having been opened in 1929, and is faster than the teleferico, which takes only 4 minutes. On its way it passes two bridges and a tunnel. It operates Mon to Sat from 7:40 am to 11:40 am and Sundays and holidays from 5:30 am to 6 pm. Both teleferico and funicular offer panoramic views of Bogota.
Also known as the Fourth Street Elevator and the world's shortest, steepest, scenic railway - 296 feet in length. Magnificent views of Iowa, Illinois, and Wisconsin. Open April through November.
