The Heitersberg line is a Swiss railway line between the Killwangen-Spreitenbach and Aarau stations on the east-west main transversal between Zurich and Bern . The main structure of the Heitersberg line is the 4929 meter long Heitersberg railway tunnel , the west portal of which is near Mellingen and the east portal of Killwangen .
The line was built early as part of the planned New Main Transversal (NHT) in the 1970s. It was opened on June 1, 1975 and put into scheduled operation on May 22, 1975.
Routing
After Killwangen the Heitersberg route branches off from the main route Zurich Baden-Aarau -Olten-Bern, and pierces the almost five-kilometer tunnel to Heitersberg (west portal at six hundred and sixty-three thousand four hundred and fifty / 253440 , east portal at 668209 / 254467 ), united in Mellingen with the National Railway of Wettingen and in Othmarsingen with the Brugg - Rotkreuz southern railway line . Outside of Othmarsingen, a three-story route was created with the cantonal road and the branching structure towards Hendschiken and Lenzburg . West of Lenzburg, a new route leads to Rupperswil and a later four-track section to Aarau.
Thanks to the new direct route, the speed through the tunnel could be increased to 140 km / h and the travel time between Zurich and Bern - also through other structures such as the gray wood tunnel near Bern - was reduced by 20 minutes.
A slab track was tested in the Heitersberg tunnel from 1975 to 2014 .
Expansion plans
Following the Heitersberg route, the Eppenberg tunnel has been under construction in the direction of Olten since 2015 and is expected to open at the end of 2020. In addition, the further expansion of the Heitersberg line was part of the Future Development of Railway Infrastructure (ZEB) program . The Chestenberg tunnel was to be built between Rupperswil and Gruemet . With the FABI template, the ZEB template was changed and the further expansion of the Heitersberg route including the Chestenberg tunnel was dropped. Instead, in the long term, a direct connection from Zurich Altstetten to Rupperswil with a 30 km long tunnel is planned. Due to the high costs of up to CHF 7 billion, implementation is realistic in a rail expansion step in 2045 at the earliest.
