The tram system is conjoined with an interurban tramway branch to Jablonec nad Nisou.

The branch between Liberec and Jablonec nad Nisou was out of service since July 2021 to May 2024 for upgrading and regauging to bring the network to an all standard-gauge track.

[1] On 11 September 1894, the Liberec City Council approved a proposal for the construction of an electric tram line with a 1,000 mm (3 ft 3+3⁄8 in) metre gauge.

[2] It was at a time when the only tram operation in the territory of today's Czech Republic was in Prague (Křižík's electric railway at Letná).

The electric tram quickly became the main mode of transport in Liberec, carrying 800,000 passengers in 1898.

The signing of the Munich Agreement meant that Liberec was seized and annexed by Nazi Germany.

On 8 October 1938, Nazi troops entered the city and tram traffic was interrupted.

Construction on the Liberec–Jablonec tramway started in 1947 and the line was finished in 1954 as a 1,000 mm (3 ft 3+3⁄8 in) single-track railway becoming operational on 1 January 1955.

[12] On 17 July 2021, trams on the 1,000 mm (3 ft 3+3⁄8 in) metre gauge were in regular operation for the last time on the interurban line to Jablonec nad Nisou.

[1] All Liberec services converge at the central tram point, Fügnerova station.
