The city of Gotha has almost 50,000 inhabitants and is located on the edge of the Thuringian Forest. It has two inner-city tram lines (1 and 2) connecting the main station with the hospital and the east station. Both together have a length of approx. 8 kilometres. The line number 3 is only used for trips from and to the depot, therefore this line operates only once or twice per day.

A special attraction is the line No. 4, the "Thüringerwaldbahn" (Thuringian Forest Tram). This interurban route runs from Gotha's main railway station on a scenic route with a length of 22 kilometres through the Thuringian Forest to Tabarz. The village of Waltershausen is connected by a two-and-a-half-kilometre-long branch line, which is designated as line No. 6.

The trams are operated by → Thüringerwaldbahn und Straßenbahn Gotha GmbH (TWSB).
