Is the new project a replacement of the previous one?Yes
The project of a third and fourth track Zï¿½rich HB - Wipkingen - ï¿½rlikon would
have meant an additional bridge with additional traffic (additional noise) in
the city. There was a strong opposition against this.
Third and fourth track would not have solved the lack of plattforms in Zï¿½rich
HB. Thus it was planned to maintain for a long time the four tracks behind
Sihlpost now under construction as a transitory solution. This would have
meant long ways to reach certain S-Bahn trains over decades. There was a
strong opposition against this.
The now adopted project of an additional four-track underground station gives
a satisfactory solution for additional plattform capactity and makes
through-running possible for all S-Bahn trains now changing direction in
Zï¿½rich HB. Additional capacity Zï¿½rich - ï¿½rlikon is gotten from the direct
tunnel HB - ï¿½rlikon.
