Muttenz – Haltingen traction power line

The Muttenz-Haltingen traction power line in the area of ​​the Muttenz marshalling yard. At the top are the Muttenz-Haltingen 1 and 2 lines. In the middle on the left, the Muttenz-Delémont line. In the middle right and below are feed lines for the contact lines (15 kV)

The Muttenz-Haltingen traction power line connects the substations of the Swiss Federal Railways in Muttenz and DB Energie in Haltingen through a four-pole network coupling point. This traction current line shares a mast with the line coming from Rupperswil and is then merged along the railway line with the line to Delémont . It used to be built above ground along the Basel connecting line to the Badischer Bahnhof ; today the underground section begins at the canalised Birs . To the right of the Rhine it is again built as an overhead line - in a single-tier arrangement with a lattice mast construction typical of Deutsche Bahn . This traction current line forms next to the traction current line between Etzwilen and Singen (Hohentwiel) one of two connections between the traction current network of Deutsche Bahn in Germany and the network of SBB in Switzerland. The line is important for the SBB because in Switzerland, unlike the situation in Germany, it has not yet been possible to achieve a close meshing between the traction power plants and the substations and the SBB's own network is therefore sensitive to incorrect loads.

At the network interconnection point there is a galvanically separated transition between the high voltage network of DB Energie with 110 kV and the high voltage network of SBB with 132 kV / 66 kV.
