# List of railway lines in Bulgaria

This is a list of railway lines in Bulgaria focusing primarily on intercity train lines. In 2019, there were 4,071 kilometres (2,530 mi) of standard gauge railways, of which 67% were electrified. Narrow gauge lines amount to 125 kilometres (78 mi).
Train railways, as well as related infrastructure such as stations, are managed and maintained by the National Railway Infrastructure Company, which split from Bulgarian State Railways (BDZ) - Bulgaria's national rail company - in 2002. The National Railway Infrastructure Company holds a virtual monopoly on ownership and works closely with the State Railways.
Non-train rail transport in Bulgaria is limited to tram and metro services in Sofia, both managed by their own municipality-owned companies.

## Urban rail transport

The capital Sofia is the only Bulgarian city with an urban rail network. These include trams and subway trains. Until 1964, a ring railway connected a number of train stations within Sofia. This abandoned railway has seen renewed interest in 2019, with proposals to either partially restore and use it for connections to Sofia Airport and subway stations, convert it into a "green ring route" for bicycles, or both. In May 2020, it was decided that parts of this railway will not be restored for train movement, but for bicycles and pedestrians instead.
Sofia's urban rail network is nevertheless integrated with the national railway network. Both the tram network and Sofia Metro have stations at Sofia Central Station, the central hub for several of the main train lines in Bulgaria.

### Trams

Operational since 1901, the tram network had 137 kilometres (85 mi) of track in 2016, servicing 14 lines with a total two-way route length of 286 kilometres (178 mi). The Sofiya tram network uses two gauges - 1009 mm (39,72 inches) and standard 1435 mm (56,49 inches).
