In the 1960s, the gauge was selected for use in the Bay Area Rapid Transit system (BART), serving the San Francisco Bay Area; it is the only place in the United States where this gauge is in use. The rapid transit segment of the system covers 109 miles (175 km) of double track in revenue service with additional sidings and maintenance facilities.
The vast majority of North American railroads are standard gauge (4 ft 8 + 1 ⁄ 2 in / 1,435 mm).Exceptions include some streetcar, subway and rapid transit systems, mining and tunneling operations, and some narrow-gauge lines particularly in the west, e.g. the isolated White Pass and Yukon Route system, and the former Newfoundland Railway.

Some amount of tolerance is necessarily allowed from the nominal gauge to allow for wear, etc.; this tolerance is typically greater for track limited to slower speeds, and tighter for track where higher speeds are expected (as an example, in the US the gauge is allowed to vary between 4 ft 8 in (1,420 mm) to 4 ft 10 in (1,470 mm) for track ...
The Oahu Railway and Land Company was the largest narrow-gauge class-one common-carrier railway in the US (at the time of its dissolution in 1947), and the only US narrow-gauge railroad to use signals. The OR&L used Automatic Block Signals, or ABS on their double track mainline between Honolulu and Waipahu, a total of 12.9 miles (20.8 km), and ...
The American gauges converged, as the advantages of equipment interchange became increasingly apparent. Notably, all the 5 ft (1,524 mm) broad gauge track in the South was converted to "almost standard" gauge 4 ft 9 in (1,448 mm) over the course of two days beginning on 31 May 1886.

This is a list of 3 ft (914 mm) narrow-gauge railways in the United States. Narrow-gauge railroads of various sizes existed across the US, especially during the late 1800s, with the most popular gauge being 3 ft gauge. [1] [2] Some of the more famous 3 ft gauge railroad networks in the US were based in California, Colorado, and Hawaii. These ...
