Delhi Metro uses Indian gauge, but new lines are built to 1,435 mm (4 ft 8 1⁄2 in).
Bay Area Rapid Transit (BART) uses Indian gauge, though most railroad lines in the United States are built to 1,435 mm (4 ft 8 1⁄2 in) gauge.

Standard gauge usage
Standard gauge usage for all lines
Some of the largest subway systems in the world use standard gauge in agreement with the country wide dominant usage for track gauge, e.g.
- Asia: Seoul Metropolitan Subway, Beijing Subway, Shanghai Metro, Mass Rapid Transit
- Americas: New York City Subway, Mexico City Metro.
- Europe: London Underground Paris Métro.
Some networks use standard gauge while the country wide standard for track gauge is different, e.g.:
- Buenos Aires Underground - country uses Indian gauge
- Santiago Metro - country uses Indian gauge
- RapidKL Rail - country standard is Meter gauge
- Manila Light Rail Transit System - country uses 3 ft 6 in (1,067 mm) gauge
- Mumbai Metro (planned) - country standard is Indian gauge
- Ho Chi Minh City Metro (planned) - country standard is Meter gauge
- Bogotá Metro (planned) - country standard is three foot gauge
- Train for the vicinities of the city of Bogotá (planned) - country standard is three foot gauge
Standard gauge usage for new lines
In some networks new lines are built to standard gauge while old lines in the network use another gauge, e.g.:
- Delhi Metro - old lines use Indian gauge
- São Paulo Metro - old lines use Irish gauge, country standard is Meter gauge
4 ft 6 in (1,372 mm) gauge
- Tokyo (Toei Shinjuku Line)
4 ft (1,219 mm) gauge
3 ft 6 in (1,067 mm) gauge
Multiple sizes in one network
In some networks multiple gauges are used even amongst lines that are built around the same time, like the Toei Subway which uses three gauges:
- 3 ft 6 in (1,067 mm) gauge (Toei Mita Line)
- 4 ft 6 in (1,372 mm) (Toei Shinjuku Line)
- Standard gauge (Toei Asakusa Line, Toei Oedo Line)
In other networks, very similar track gauges may be used, as is the case with the Hong Kong MTR (1,432 mm (4 ft 8 3⁄8 in) and 1,435 mm (4 ft 8 1⁄2 in)).
