Bellevue

Bellevue in Zürich is quite a big tram venue. That's where you change when going in something like 5 different directions. But now they've decided to do something fabulous on that big square, so trams are re-directed during a period of several months. Very confusing today when I came from Acqua, walking all the way to Bürkliplatz, taking a tram one stop to Bellevue and thinking of changing to tram No 4 to Central. Only I had to walk towards Central, then take a tram back to Bellevue, see it pass Bellevue where it used to stop (waving at the confused people waiting at the old tram stop) and finally proceed towards Central. How did they think when they planned this?
