Seven lines operate on approximately 16 kilometres (9.9 mi) of track, which makes it the smallest tramway network by length in the Czech Republic.

Work began on a standard-gauge electric tram in 1897 and the first line opened to public on 1 April 1899.

As in other cities at the time, such as Ústí nad Labem or České Budějovice, there were proposals to decommission tram transport and replace it with buses, although this never happened.

From 1 September 2007, line 5 which led from Pavlovičky around the main train station via Tržnice to Neředín was closed.

By the end of August 2007, a six-month reconstruction of Denisova and Pekařská streets in the city center was complete.

In 2022, this was the list of routes: Passengers must buy and validate a ticket immediately after boarding a vehicle.

There are plainclothes fare inspectors who randomly check passengers' tickets within the paid area; they are equipped with an inspection badge and carrier ID.

On night lines 50, 51, 52 the passengers are required to board through first door of the bus and show their ticket to the driver.
