Grudziadz is the smallest city with a tram network in Poland. A substantial part of the system is single-track with passing points. The Route 2 is the principal service, operating via the main south – north corridor. The feeder Route 1 used to serve the main Railroad Station. After a decade of on-and-off operation, the service on the Route 1 is now discontinued due to rolling stock shortages.

The Route 1 was temporary suspened between 01.12.2005 - 01.06.2006. It was suspended again on 13.08.2011.

The northern line to Tarpno, which includes the segment through the old town and the main Market square, is entirely single-track with passing points on a mixed righ-of-way. So is the eastern line to the Main Railroad Station and the Depot, except for the small segment on a reservation. The Main Railroad Station Terminal is one of only three 3-point terminals in Poland (the other two are in Lodz and Katowice). The terminal also happens to be the only tram terminal in Poland explicitly adjacent to the city’s Main Railroad Station. The southern line to Rzadz is mostly double-tracked, except for the 900-meter segment on approach to the short turn loop at Poludniowa. The part of the line located closer to the city center is on a mixed right-of-way, while the outer segment is on a reserved siding. The 1.9 km. single-track segment between Poludniowa and Mniska, serving the industrial park to the south of the town, was opened in 1978, but closed a year later due to unstable soil. The newest segment between Poludniowa and Rzadz opened as a single track in 1996, but was double-tracked a year later.

Timetable: 2012

The system is meticulously run as it must adhere to a single track infrastructure. The weekday daytime timetable for the Route 2 lists the 8 min. headway, which calls for trams to meet at every passing point. Depot runs to the Railroad Station via the former Route 1 do carry passengers.

A total of 23 cars:

	9 Konstal 805Na cars (1980-1986): 38, 41, 42, 46, 47, 49, 58-60

	2 Duewag GT6ZR cars (1962, 1963) single-articulated, double-ended ex-Wurzburg: 77, 78

[ 2012 ] A total of 30 cars: 8 Konstal 805Na cars (1980-1986): 38, 42, 46, 47, 49, 51, 56, 60 6 Konstal 805Na cars (1980-1986, rebuilt 2010): 89-94 6 Konstal 805Nb cars (1993) ex-Warsaw: 63-68 10 Duewag GT8 cars (1972-1976) doubel-articulated, ex-Krefeld: 79-88

All Polish-built Konstal 805Na cars are form the early 1980s. 6 Konstal 805Na cars were radically rebuilt in 2010 and renumbered into 89-94. After a destructive fire at the Depot on 05.09.1993 and a loss of 11 Konstal 805Na cars, the city received 6 hand-me-down Konstal 805Nb trams from Warsaw. In 1998-2000 the city acquired 2 Duewag GT6 single-articulated trams (1964) second-hand from Manheim and 6 Duewag GT6 single-articulated trams (1962,63) from Wurzburg, 2 of which were bi-directional. In 2010 7 of these continued on to Lodz, minus car 73 that was salvaged for parts while in Grudziadz. At the same time the city acquired 10 Duewag GT8 double-articulated trams (1972-76) second-hand from Krefeld.
