Eurail Pass is valid in Europe but not in Britain. Throughout 2008, travelers ages 16 to 25 who purchase any Eurail Pass (about $69-$2,089) can get a 50% discount off the regular adult price of a standard-class BritRail Consecutive Pass, BritRail FlexiPass, BritRail England Consecutive Pass or BritRail England FlexiPass.
Examples — with the 50% discount, the “all-access” standard-class 4-Day BritRail Consecutive Pass costs $130 and the FlexiPass version, $165. Contact BritRail (866/938-7245, www.britrail.com).
