Next weekend the third and final elevator placement will take place at the central railway station of Hoorn. Just came by the station, and saw that a lot of the preparations have already been done. As you can see at the pictures, the structure of the elevator is already at location.
Trains versus elevator placement
The big problem with train stations is that there are a lot of trains, so the elevator placement has to wait until next weekend. Because of that no trains will be coming to Hoorn at all, they will be replaced by buses.
