Three foot six inch gauge railways in the United States

A list of 3 ft 6 in (1,067 mm) gauge railways in the United States. Apart from historical railways, it is commonly used in underground coal mines.[1][2] Also, in the past, this gauge had been a popular choice for urban mass transit systems (see table below).

The San Francisco cable car system is the last manually-operated cable car system in the world.
