The Sofia Tramway began operation January 1, 1901. As of 2006, the tram system included approximately 308 kilometres (191 miles) of narrow and standard gauge one-way track. Most of the track is narrow gauge, with standard gauge used on lines 20, 22 and 23, accounting for approximately 39 km (24 mi) of the system's track length.
On 1 December 1898 the capital municipality gave concessions for building tram lines to French and Belgian companies. Construction took place for a little more than a year and the first tram line was inaugurated on 1 January 1901. Initially the population was served by 25 motor cars and 10 trailers which covered six lines with total length of 23 km (14 mi) and gauge of 1,000 mm (3 ft 3 3⁄8 in) metre gauge.
In the period between 1901 and 1931 large numbers of motor cars and trailers were purchased from different European manufacturers. In 1931 Bulgaria started building their own carriages under the supervision of the engineer Teodosiy Kardalev. These were known as Kardalev's carriages. In 1936 the first Bulgarian motor cars were produced under the brand DTO (Directsiya na Tramvaite i Osvetlenieto: Bureau for trams and lighting, owned by the city). Initially old frames were used for the production.
In 1934 the first large tram depot was built in the Krasno selo district. In 1951 a factory to build newer model tram cars was constructed there. Through 1959 it produced 155 DTO and Republika motors, which were the first fully Bulgarian-built trams. The last tram, T8M-900 was delivered in 1991 and is still in use. Since then the factory has been used to repair and renovate old trams.
Sofia's first standard gauge tram line was opened in 1987. Until that time all lines were nominally metre gauge, but actually constructed to a width of 1,009 mm (3 ft 3 23⁄32 in). Eight years later, in 1995, the second standard gauge line was finished. No other tram lines have been built since then, as Sofia has focused its efforts on the construction of its metro system.
