I'm continuing my journey through Netherlands
Intercity train to Amsterdam
The new thing from this year is that the Interrail pass is now digital as a QR code on mobile phones. Unfortunately I had several issues with the pass, as it could just disappear when I had to show it to the conductor. It was very annoying, but later on, the issue was resolved.
A key is available, but there is not much use of it as there is no restaurant car in the train
It is possible to buy drinks and food that can be brought to the compartment, but I had bought the food at the station in advance
