Sofia Suburban Railway

Bulgaria’s only underground system

At 40 km in length, the Sofia Metro is currently the only metro system in Bulgaria. Opened on January 28, 1998, it currently consists of two lines and 34 stations. Around 450,000 passengers use the metro network in Sofia each day.

A third line has been under construction since 2015. In contrast to the two other lines, the trains on the third line will be supplied with electricity via an overhead line, and all stations will be fitted with platform screen doors.

Our solutions

Around 5,000 height-adjustable conductor rail carriers are responsible for the traction power supply along the Sofia metro network.
