no this only takes one travelday the day of depature.

I see the same problem. If I select the night train from Prague at 21.00 to Krakow Glowny at 06.06 on the app, it takes 2 travel days because it seems there is a change. However, I checked on the CD website and it looks as a direct train (I also asked to the CD customer service and they confirmed that). Do you know why it happens?

The train splits multiple times during the night: carriages from Berlin, Munich and Prague to Budapest, Warsaw, Humenné, etc.

The app can’t handle that and sometimes planners struggle too. Add the journey manually.

Got it, thanks! And is that why on CD website I see that at Bohumin station it stops for more than 2 hours and a half, and it’s written “to train EN 406”?
