Once you return home from Europe, you submit a claim with the police report and proof of other tickets bought. You do not get refunded for the additional tickets or passes you buy in Europe. You activate a pass by presenting the railpass to a rail official in any rail station in Europe whose country is affiliated with that pass. They will check you passport to the name on the pass and then stamp the pass. This stamp begins the clock ticking on the validity period of that pass.
Many passes also have the start date and ending date then placed on the railpass.
A Saverpass is a discounted Eurailpass for two or more people traveling together at all times. This is the best and most direct way to make reservations. Another way is to make the reservations through Forsyth at the time you order your passes or tickets. Otherwise, look at the rail station schedule boards, pick up general regional schedules, full national schedules or the Thomas Cook European Rail timetable through Forsyth travel library. Flexipass gives you a little more freedom to travel over a longer period of time.
