The Duquesne Incline ( dew-KAYN) is a funicular scaling Mount Washington near the South Side neighborhood of Pittsburgh, Pennsylvania, United States. The lower station is in the Second Empire style. Together with the incline, which rises 400 feet (122 m) in height, at a 30-degree angle, it was listed on the National Register of Historic Places in 1975. The incline is unusual for using a 5 ft (1,524 mm) track gauge, mainly used in Finland, Russia, and Mongolia. Together with the Monongahela Incline, it is one of two passenger inclines still in operation on Pittsburgh's South Side. By 1977, the two had become tourist attractions and together served more than one million commuters and tourists…

Railways with a railway track gauge of 5 ft (1,524 mm) first appeared in the United Kingdom and the United States. This gauge became commonly known as "Russian gauge", because the government of the Russian Empire chose it in 1843. Former areas and states (such as Finland) of the Empire have inherited this standard. However, in 1970, Soviet Railways redefined the gauge as 1,520 mm (4 ft 11+27⁄32 in). With about 225,000 km (140,000 mi) of track, 1,520 mm is the second-most common gauge in the world, after 1,435 mm (4 ft 8+1⁄2 in) standard gauge.

Originally, various track gauges were used in the United States. Some railways, primarily in the northeast, used standard gauge of 4 ft 8+1⁄2 in (1,435 mm); others used gauges ranging from 2 ft (610 mm) to 6 ft (1,829 mm). As a general rule, southern railroads were built to one or another broad gauge, mostly 5 ft (1,524 mm), while northern railroads that were not standard-gauge tended to be narrow-gauge. The Pacific Railroad Acts of 1863 specified standard gauge be used for the first transcontinental railroad. Notable exceptions were the 6 ft (1,829 mm) railroads that predominated in the first part of the 19th century in New York State, and the 5 ft 6 in (1,676 mm) lines centered on Portlan…
