|Tools for this tag|
Definition according to Transportation Research Board: "A mode of urban transportation utilizing predominantly reserved but not necessarily grade-separated rights-of-way. Electrically propelled rail vehicles operate singly or in trains. LRT provides a wide range of passenger capabilities and performance characteristics at moderate costs.
There is no clear definition of light rail on OSM, the distinctions between conventional rail (rail), tram (tram) and subway (subway) are fuzzy. A light rail system should be mapped consistently, as long as there are no serious differences. Further below are some recommendations from railway mappers which should support the selection. In order to avoid conflict, please seek consensus on the forum or mailing lists before retagging.
The community of OpenRailwayMap has compiled a set of recommendations at their Aktiventreffen 2014 nr. 2.
- connections to conventional rail are not a factor
Strong criteria for light rail against tram:
- Trams are driving on sight, while light rail has signals.
- Light rails are driving faster than trams because of own right of way and more complex signaling and protection.
Soft criteria for light rail against tram:
- own right of way
- underground railway
- elevated railway
- workrules like conventional rail
- drives overland to the surroundings
- constructed stops rather than simple bus-like stops at the road level.
- stops are separating the passengers from the tracks
- presence of so-called third rails
