Maybe you're lucky or my route is cursed, either way I hope you don't have to go through my awful experience. I've had hours of delays over the past year (and it is making me angry). It's sad but when I would see the delay was on 5mins I would do sigh of relief because 15-20min delays were becoming common and a 5min delay at this point becomes tolerable. Also to add extra salt to the wound, the train would leave 10mins and then wait an extra 10mins in front of the Lausanne station because reasons. In the end a 10min trip became 30mins.
