If you can spare the time and effort it is worthwhile looking at splitting your rail journey up to get a better deal. However it is very easy to get side-tracked by all the possible options of routes and times. The web site http://www.ticketclever.com aims to cut the cost of rail fare by up to 60%.. As  with all rail travel sites you specify the dates you want to travel, the number of people travelling and the number of rail cards held. TicketClever then works out the route and fares for you.
