A railway siding , even Stutz track , Sack track , head track , Blind track , dead track , track fitting , in Switzerland head track or if there is a siding, dead track called, is a track that only one end of a switch connecting one and at the other end defined, not to be traversed point. The latter is often the end of the rail, which is usually terminated by a track end ( buffer stop or similar construction). However, the end of the rail can only be a few kilometers behind the end of the track. At the switch, the track ends by definition at the heart of the switch. In a terminus station , all tracks are butt tracks. Even switchbacks need a dead-end track.

Tracks that have a turnout connection at one end but lead to a turntable , transfer platform or loading bridge of a ferry company at the other end are not referred to as dead ends.

In the Deutsche Bahn network , the maximum permissible speed for train journeys in butt tracks is generally limited to a maximum of 40 km / h. In the area of ​​the former Deutsche Bundesbahn , entrances to butt tracks may only be projected at 30 km / h. Particularly short dead ends may only be entered at the speed specified in the operating register. Possibilities for increasing the speed, such as constant monitoring of the entry speed, have not yet been implemented for reasons of cost (status: 1987).

Butt tracks also exist on light rail vehicles and trams . They are mostly to be found in the form of so-called stump ends if the respective transport company uses bidirectional vehicles or if it is stump tracks at a turning triangle . Another variant are butt tracks for changing the direction of travel at intermediate end points - in some cases also arranged as a turning system between the two direction tracks - or in the form of siding for emergency vehicles , theater cars , work cars or reserve cars . Butt tracks are also often found within turning loops ; these are used, for example, to temporarily park damaged wagons. Sometimes there are stump ends in the tram area without any end of the track .
