For the staging of the FIS World Ski Championships in February 2017, the St. Moritz railway station had to be completely rebuilt and made more user-friendly. To meet this requirement, the new Interlocking System had to be put into operation by the end of October 2015. For the total refurbishment of St. Moritz station, a total of 12 extension phases in both the old and the new Interlocking System were necessary.
