A rail pass is a pass that covers the cost of train travel in a certain designated area or areas within a certain period of time.[1] It is contrasted to a point-to-point ticket in that it allows the holder unlimited travel, within the pre-designated area and period, while a point-to-point ticket only permits the holder to travel from a point to another once. It is different from a season ticket in the sense that, while both of them grant unlimited travel to the holder, season tickets normally target commuting travellers, whereas rail passes usually target tourists. Based on this difference, terms of use are thus normally set differently.
The first rail pass was issued as the Eurail pass in March 1959. Owing to its success, many other passes have been issued by various railway companies all around the world since then.
