WHICH WAY TO GO? - A BASIC GUIDE TO UK RAIL ROUTEING
There are several ways in which the routeing of your ticket is determined
(1) The route that is shown on the ticket.
(i) You must pass through any station that is mentioned as “VIA” on your ticket*
(ii) you must not pass through any station mention as “NOT” on your ticket*.
(iii) If a ticket states a train operating company (TOC) you may only travel on trains operated by that company (if it mentions two or TOCs you may only use those TOCs)*
(2) You can always travel by the shortest route (or any route that is no more than 3 miles longer than that route) as long as that route conforms with condition (1) above.
(3) You can always travel by a through train to your destination as long as it satisfies condition (1) above
(4) Use the National Routeing Guide published by ATOC to find what additional routes are available.
* There are certain circumstances where these tickets have extra validity (see our Guide to the National Routeing Guide for further details).
