The Bucharest light rail (Romanian: Metrou uşor or "light metro") is a light rail transit system in Bucharest, Romania.
Operated by the Regia Autonomă de Transport București (RATB), the municipal public transit operator, the service is technically similar to a light rail and not to a light metro system.
Light rail use more modern rolling stock than trams and also run on separate designated corridors for faster travel times.
The first line (41) was opened in 2002, and runs through the west part of the city (from FC Steaua Bucureşti's Ghencea stadium in the south-west, to the Casa Presei Libere in the north).
While not exactly light rail, tram lines 32 and 21 can be considered as being light rail due to their low waiting times and sometimes superior speed.
