History
The charter for this railway entered the planning phase by January 1890, with a target filing date of February 8 of that year, and was originally to be called the Arlington Avenue Inclined Plane. The last day of service was December 3, 1960, and it was demolished before the year ended. It was designed by John H. McRoberts, with a length of 2644 feet.The Knoxville Incline briefly controlled the Pittsburgh, Knoxville & St. Clair Electric Railroad, and was then later controlled by Pittsburgh Railways. During its operation, the incline ferried people and freight between the South Side and Knoxville.
