The comission is planning changes to train travel in Europe to make it less of a headache for passengers.
-Single booking tickets that work across different operators.
-Passenger safety nets such as reroutings, reimbursements and compensations.
-New rules for operators and platforms to ensure fair pricings and route options.
Where do you book? Afaik this is not a thing everywhere
To my understanding there are multiple european places to shop. https://b-europe.com/ seems to work fine. It doesn’t show all options though so it’s not perfect. When you call them you could get extra options. You may want more time between connections or such and they can combine that where the online interface doesn’t.
