Does anyone have a link of the lines that are strictly Eurail lines? I keep finding maps of the trains that go from city to city in Europe when I search. Or, does the Eurail allow to go city to city like that? I'm assuming it only goes to a few major cities in each country. Any help would be greatly appreciated!
Yes, the Eurail allows you to go city to city like that. Here's a good map.
Bear in mind that not all trips are entirely covered by Eurail - some trips have surcharges, reservations usually cost extra and overnight sleepers cost extra as well. Sometimes it still works out cheaper to just buy point to point tickets - depends on the distances and locations.
What is the best way to determine the best pass for your trip? For a trip such as the one in this post I can't figure it out..... http://www.travellerspoint.com/forum.cfm?thread=13866
