Railway electrification in Japan
Japan's conventional mainline railway network schematic map showing electrification systems with voltages and frequencies as of 2017. Third-sector railways are included. Shinkansen exclusive-use trackage is not included. Municipal subways and other rapid transit networks are not included. Private railways are not included. This is a list of Railway Electrification Systems Overhead line power supply, unless otherwise noted. The rail system consists of the following (As of 2005[update] [ 1]
20,264 km (12,591 mi) of 1,067 mm 3 ft 6 in ), of which 13,280 kilometres (8,250 mi) is electrified;
3,204 km (1,991 mi) of 1,435 mm (4 ft 8+ 1 ⁄2 in ) standard gauge
117 km (73 mi) of 1,372 mm 4 ft 6 in ) Scotch gauge , all electrified;
11 km (6.8 mi) of 762 mm 2 ft 6 in ) narrow gauge , all electrified. Electrification systems used by the Japan Railways Group , Japan's formerly state-owned operators, are 1,500 V DC and 20 kV AC for conventional lines and mini Shinkansen and 25 kV AC for Shinkansen . Electrification at 600 V DC and 750 V DC are also seen in private lines and non-rail based transit systems. The frequency of the AC power supply is 50 Hz in Eastern Japan and 60 Hz in Western Japan.
