The tram network in Most consists of an inner city route and an interurban line to the neighboring town of Litvinov. The system length is 18 kilometres. The history of the tram is as interesting as that of the city: in the 1970s, the city had to make room for the extending brown coal mining in the area. It was demolished and rebuilt two kilometres south, but almost entirely from prefabricated buildings. Accordingly, the tram within Most was also completely re-arranged until 1978. The interurban tram was already developed to a completely double-track rapid connection in the 1960s.
The trams are operated by → DPmML (Dopravní podnik měst Mostu a Litvínova, a.s.)
