List of current systems for electric rail traction
This a list of the voltages, etc. that are used or have been used for railway electrification systems.
Key:
- Volts: voltage
- Hz: DC=direct current or frequency in Hertz if alternating current; single-phase except where marked three-phase
- Conductors: overhead lines or third rail
- see - streetcar, tram, light rail
| Volts | Hz | Conductors | |
|---|---|---|---|
| 180 | DC | → | Siemens streetcar Berlin-Lichterfelde 1881-1891, current feed over the running rails! |
| 500 | DC | many streetcars | |
| 525 | DC | overhead | Bergbahn Lauterbrunnen-Mürren |
| 600 | DC | overhead | very common for older tram systems world wide |
| third rail | was used for trams in central London - third rail accessed via a slot between the tracks Metro-North Railroad (Hudson & Harlem lines, southern part of New Haven line), the USA parts of British Rail Southern Region up to 1939 | ||
| third and fourth rail | London Underground | ||
| Most older US subways, PATH | |||
| 725 | 50 Hz three-phase | overhead two wire | Gornergratbahn |
| 750 | DC | overhead | most modern tram systems including, in Germany (Stuttgart, Cologne-Bonn, Frankfurt am Main, etc.) Albtalbahn, railway of the Upper Rhine, Rhein-Haardtbahn local lines of Stern & Hafferl in Austria |
| third rail | Undergrounds in Russia, Prague, Berlin, Munich, Nuernberg, Hamburg, Vienna, Budapest, Bucharest Long Island Railroad (USA), most of Southern Railway, England - see also external link | ||
| bottom contact third rail | Docklands Light Railway | ||
| Washington, D.C. Metro | |||
| 800 | DC | third rail | Rapid-transit railway Berlin |
| 850 | DC | Local railway Vienna | |
| 860 | DC | Switzerland (MOBILIZATION) | |
| 900 | DC | Switzerland (GFM) | |
| 1000 | DC | Switzerland (SZU) | |
| 1125 | 50 Hz three-phase | overhead two wire | Jungfraubahn |
| 1200 | DC | overhead | to 1985 KBE, Cuba (FdeC), Spain (Sóller Railway) 900 mm gauge Grubenbahnnen in the Niederlausitzer brown coal district |
| third rail | Rapid-transit railway Hamburg Manchester to Bury line - obsolete | ||
| 1350 | DC | Domodossola Locarno | |
| 1500 | DC | rural lines in Australia, the Netherlands, France, Slovenia, Czech Republic, Denmark (rapid-transit railway Copenhagen), India, Ireland, Japan, Switzerland (BOB, SPB, WAB), Spain (Catalan Railways, Spanish national Railway, Euskotren, FEVE), the USA (Metra, lines around Chicago) Manchester - Sheffield (via the Woodhead Tunnel) from 1954 to 1981 | |
| 2400 | DC | Work line of the Lausitzer brown coal AG | |
| 3000 | DC | rural lines in Poland, Belgium, Italy (except Sardinia) (changing to 25 kV AC), former Soviet Union, Brazil, Chile, North Korea, Slovakia, Spain (changing to 25 kV AC), South Africa, Czech Republic | |
| 3600 | 16 2/3 Hz three-phase | overhead two wire | from 1912 to 1976 in upper Italy |
| 6000 | DC | attempts in Russia | |
| 6250 | 50 Hz | Factory railway of Rheinbraun AG | |
| 6300 | 25 Hz | Mariazeller Bahn | |
| 11000 | 16 2/3 Hz | Rhaetian Railway, Furka-Oberalp-Bahn | |
| 11000 | 25 Hz | Amtrak Northeast Corridor (NEC) (Washington, DC and Harrisburg, PA to New York City), SEPTA, New Jersey Transit, the USA | |
| 12500 | 60 Hz | Amtrak NEC and Metro-North Railroad (Queens, New York to New Haven), the USA | |
| 15000 | 50 Hz three-phase | overhead three wire | trial runs between Zossen and Marienfelde , 1901 to 1904 |
| 15000 | 16 2/3 Hz | since 1912 standard system in Austria, Germany, Norway, Sweden and Switzerland | |
| 20000 | 50 Hz | Höllentalbahn from 1933 to 1960 Japan | |
| 20000 | 60 Hz | Japan | |
| 25000 | 50 Hz | Great Britain, Slovakia, former Soviet Union, Germany, Hungary, Romania, Bulgaria, Greece, Turkey, Sardinia, Denmark, Australia, China, Czech Republic, India, Iran, Italy (new installations), Malaysia (KTM Komuter Service) ,South Korea, Portugal, Slovakia, Spain (new installations), South Africa, Rübelandbahn Harz | |
| 25000 | 60 Hz | Amtrak NEC (New Haven to Boston), New Jersey Transit (newer lines), USA, Tokaido-Sanyo Shinkansen, Japan, South Korea | |
