How to check your train status online?

It's easy to check the status of your train online. Most European rail operators have a departure board or traffic forecast tool on their websites. Note that most journeys won't appear until a day before travel. 

Most sites will ask you to enter your train number. You can find this in your confirmation email, or on your ticket.
