Narrow Gauge
Narrow gauge railways generally have smaller a loading gauge than standard gauge ones, and this is a major reason for cost savings rather than the railgauge itself. For example, the Lyn locomotive of the Lynton and Barnstaple Railway is 7 feet 2 inches (2.18 m) wide. By comparison, several standard gauge 73 class locomotives of the NSWR, which are 9 feet 3 inches (2.82 m) wide, have been converted for use on 610 mm (2 ft) cane tramways, where there are no narrow bridges, tunnels or track centres to cause trouble. The 6E1 locomotive of the 1,067 mm (3 ft 6 in) South African Railways are 9 feet 6 inches (2.9 m) wide.
A large numbers of railways using the 762 mm (2 ft 6 in) gauge used the same rolling stock plans which were 7 ft 0 in (2.13 m) wide.

Famous quotes containing the word narrow:
“Men have broad and large chests, and small narrow hips, and more understanding than women, who have but small and narrow breasts, and broad hips, to the end they should remain at home, sit still, keep house, and bear and bring up children.”
—Martin Luther (1483–1546)
