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.

If the difference between the two gauges is large enough – for example between 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge and 3 ft 6 in (1,067 mm) – three-rail dual-gauge is possible, but if not – for example between 3 ft 6 in (1,067 mm) and 1,000 mm (3 ft 3 + 3 ⁄ 8 in) metre gauge – four rails must be used. Dual-gauge rail lines ...
In 1849, the Erie and North East Railroad started laying track east from Erie to the New York–Pennsylvania border, 20 miles (32 km) away, at a gauge of 6 ft (1,829 mm). [1] At the same time, the Franklin Canal Company was laying track west from Erie to the Ohio –Pennsylvania border and the Buffalo and State Line Railroad was laying track ...
The gauge is set by the positioning of the cast-in fixings, so it is not a simple task to re-gauge existing track; it also creates problems with spot replacement of sleepers. Many sleepers were made with the reduced track gauge but 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge versions have also been manufactured in more recent times. [27]
This is a category for all broad gauge railways built with a track gauge of 6 ft (1,829 mm). Subcategories This category has the following 4 subcategories, out of 4 total.
Modern national railroad network; see Track gauge in the United States; The Washington Metro uses 4 ft 8 + 1 ⁄ 4 in (1,429 mm) gauge, which is 6 mm (0.24 in) narrower than standard gauge. The Bay Area Rapid Transit system uses 5 ft 6 in (1,676 mm). The San Francisco cable car system uses 3 ft 6 in (1,067 mm).
The whole system was built to 6 ft (1,829 mm) broad gauge, the same as the New York and Erie, although the original I&O was built to standard gauge and converted to wide gauge when rebuilt as the C&S. The "Delaware and Cobb's Gap Railroad" was chartered December 4, 1850, to build a line from Scranton east to the Delaware River.
