When you buy a Eurail Pass, you are given a "travel package". This package consists of a Eurail Pass Cover, a Eurail Traveler’s Guide, a Eurail Map and a Eurail Timetable.
These documents will inform you on Eurail conditions of use, and will provide you tips to help you organizing your journey, so that you can make the most of it.
In the section "Eurail documentation", you will find links to download the PDF version.

In the other sections, you will also find the conditions applying to travel by train and to the products you bought. It summarizes the rights and obligations we have to each other.
