Kraków Fast Tram (Polish: Krakowski Szybki Tramwaj) is a light rail network being developed in Kraków alongside the existing tramway.

It consists of several modernized or purpose-built tram tracks with radio-controlled absolute priority on crossings, a 1.4 kilometres (4,600 ft) long tunnel under Kraków Główny railway station with two underground stops and a 0.6 kilometres (0.37 mi) long overpass over Kraków Płaszów rail station.

Unlike many light rail systems, Kraków Fast Tram is not separate from regular tramway lines: the tracks are a part of the wider "classic" tramway network and are used by ordinary trains, which benefit from moving through a fast tram corridor.

The stops at the fast tram tracks are equipped with an electronic passenger information system showing estimated departure times live.

The first fast tram line was opened on 12 December 2008,[1] more than 30 years since construction started;[2] however due to the missing tracks through Płaszów, it temporarily used the link through Kazimierz and Podgórze districts, where short lengths of track were not in its own right-of-way but were connected to the traffic light control system and passenger information system.
