Imagine this...

We're dedicated to saving you money on your train tickets. We do this by using a technique called "splitting". Imagine the following scenario:
An Off-Peak ticket to return the same day between Birmingham and Leeds costs £75.50 (Jul 2023). However, you can buy a ticket from Birmingham to Derby, one from Derby to Sheffield and one from Sheffield to Leeds for a total of £49.30, saving £25.80. At peak times, the savings can be much bigger.
These tickets are valid on exactly the same trains and you don't have to get off the train where you change from one ticket to another. The only thing that you must check is that the train stops at every station where you split tickets. So in this case, your train would have to stop at Derby and Sheffield. You would not be able to use any train that didn't.
We automate the search for these split tickets by looking through the entire fares database until it finds the cheapest options it can for both Advance and Flexible tickets as well and First and Standard Class. If we save you money, we charge a small percentage of the saving we found for you.
