Plan before you go. You can search the online timetable if you wish, available from the following link.
For the most extensive listing of schedules, the Thomas Cook Timetable is the best book you could have, updated monthly. The Thomas Cook Timetable contains schedules for every major route in Europe and is an invaluable aid for those travelling Europe extensively. The timetable is published in the UK on the first day of each month, and is available via major newsagents and bookshops.
The main hall of every train station in Europe contains a departure and arrival board. Platform numbers, stops made en route as well as final destinations are displayed. In each train station pocket timetables may also be available free of charge. These "mini-timetables" typically list departures and arrivals between two specific points or region. Look for them near the rail information centres.
Finally an additional source for detailed schedules is the Rail Information Centre. Relying on computerized reservation systems the centre's staff can make short work of finding a schedule or routing for you to the city of choice – and best of all the service is free.
