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 București's Ghencea Stadium in the south-west, to the House of the Free Press in the north).
At Bucur Obor (Șoseaua Colentina), it meets route 36 for a short distance, although they have no common stops.
They form a ring around central Bucharest, with line 10 running services clockwise (from Romprim – Piața Sudului – Șura Mare – Șoseaua Viilor – Pasaj Basarab – Bucur Obor – Pod Mihai Bravu – Piața Sudului – Romprim) and line 1 running services counterclockwise (from Romprim – Piața Sudului – Pod Mihai Bravu – Bucur Obor – Pasaj Basarab – Șoseaua Viilor – Șura Mare – Piața Sudului – Romprim).
In 2021, it entered in rehabilitation, from Bd Timișoara to Șoseaua Grizăvești, in order to accommodate new rolling stock.
The lines got deviated again due to a fire at an electric transformer station on Nițu Vasile Str.
Also line 10 got Imperio trams from Militari depot starting from May 2023, but also fleet will be constituted from Bucur LF, and V3A-CH-PPPC and probably V3A-93, depending on the demand.
Only downside might have been considered old rolling stock, but 12 new trams, full low floor, Imperio Metropolitan started to run on this line from March 8th 2023.
