Since 1870, residents of the Mount Washington neighborhood of Pittsburgh, Pennsylvania, have relied on the Monongahela Incline funicular to commute up and down its steep hill. People build funiculars when a hill is too steep for a train to climb.
Often described as half-train, half-elevator, funiculars have cars running on tracks, like trains, that are pulled along by cables, like elevators. Also like elevators, funiculars traditionally use a counterweight system. The force of gravity pulling down on a counterweight helps lift the funicular car.
In the case of true funiculars, two cars are connected by cables in a pulley system, one car going up, one car going down. The force of gravity on the descending train helps pull the ascending train up the slope.
Pittsburgh’s Monongahela Incline is the oldest passenger funicular in the U.S. The Allegheny Port Authority, which runs the funicular, tries to keep it looking and feeling original. That means no electricity in the cars—and no air-conditioning!
“In the winter, they’re cold, and in the summer, they’re hot,” says spokesperson Adam Brandolph. “But it’s worth it for the spectacular view.”
