Thomas Cook European Timetables
As a companion for your train journey through Europe we highly recommend you the Thomas Cook European Timetables. It provides compact information, available in a summer and a winter edition.
They include all European countries and simplify the travel planning during your trip. It could be described as "The holy bible of rail passengers".
The Thomas Cook European Rail Map can be useful in addition to the schedule book. Not a must, but a nice addition.
Both are available directly via Thomas Cook Publishing or in the travel book section here at Raildude.
The Thomas Cook European Rail Timetable isn't available anymore. It will be published under another name in 2014.
