List of tram and light rail transit systems
The following is a list of cities that have current tram/streetcar, or light rail systems as part of their regular public transit systems. In other words, this list only includes systems which operate year-round and provide actual transit service, not ones that are primarily tourist services, are seasonal-only, or are excursion-type tram operations.
Some transit systems branded as "light rail" such as the Docklands Light Railway in London or the Ampang and Kelana Jaya lines of Kuala Lumpur qualify as metro systems and thus are not listed here – see List of metro systems.
Only currently operational tram and LRT systems are included in this listing – tram and LRT systems that have "suspended operation" or are presently under construction are excluded.
