The Duquesne Incline has provided a rapid rail transit service, between Downtown Pittsburgh and the Mount Washington neighborhood of Duquesne Heights, for commuters and tourists since 1877!
At the Upper Station of the Incline, people can view the beautiful Golden Triangle of Downtown Pittsburgh, and environs, from the visitor observation deck. This beautiful view has been designated as the second most beautiful view in America by USA Weekend magazine!
In 2004, a new viewing deck was added, allowing visitors to watch the historic Incline hoisting equipment in operation. Additionally, the Upper Station waiting room includes a small museum of Pittsburgh history and cable car history.

Opened on May 20, 1877 by the Duquesne Incline Plane Company. Acquired in 1964 by the Port Authority of Allegheny County, Pittsburgh's public transit agency. From that time, the Port Authority has leased the Incline, for day-to-day operation, to the Society for the Preservation of the Duquesne Heights Incline, for one dollar per year.
