Built To Last - The Duquesne Incline, Pittsburgh, Pennsylvania - Episode 5

The Duquesne Incline, opened in 1877, stands as a testament to Pittsburgh's industrial prowess. Unlike conventional railroads limited by grades, the incline conquered steep slopes with a 30-degree incline, facilitating commutes up and down Mount Washington. Closed briefly in 1962, preservation efforts quickly restored operation, serving both tourists and commuters since.

Designed by Samuel Diescher, the incline's simplicity and efficiency are remarkable. Operating with two cars in tandem, each descending car pulls the ascending one, enhancing system efficiency. Steel cables by John Roebling, known for his bridge designs, ensured reliability. Originally steam-powered, the incline switched to electric motors in 1935, demonstrating adaptability.

Diescher's design incorporated internal protection mechanisms, such as maple gear teeth, preserving the massive drive wheel in case of malfunction. This foresight ensured longevity and minimized downtime, vital in Pittsburgh's bustling industrial landscape.

In summary, the Duquesne Incline stands as a timeless example of expert engineering, built to last and adapt to changing times.
