A woman in Cornwall needed to go to Manchester to get a car. The train fare was so expensive that she flew to Malaga in southern Spain & then flew to Manchester and it worked out cheaper due to the madness of the British Rail fares system. You may be able to read the BBC report on the woman’s trip here - but the BBC may block foreigners from reading it.
Incredibly, some through fares are dearer than splitting the journey into separate legs at places where the train stops (you stay on the same train) - or you change trains. Scotrail (as mentioned above) is an excellent site for finding a split and it does not charge commission. However, Scotrail only finds you ONE split and on some journeys, multiple splits work out even cheaper.
Let us take as an example a journey that many foreign tourists like to take - Bath to York. Now, you could go via London but that involves getting from Paddington to King’s Cross. An easier way of doing it is to go on the 15 minute journey from Bath to Bristol Temple Meads and then take a direct Cross Country Train to York. So. let's assume we are going to do that journey on Thursday 27 February and we put in to depart Bath at 9.30am. It so happens that we can leave Bath at 9.48 (for Bristol & change of train) to arrive York at 14.30.
If we were to book direct with the train company > https://www.crosscountrytrains.co.uk/ it will cost a whopping £111.00 for what they call a Super Off Peak Single. (It would be £151.70 return if made off peak. So, they rip us off if just going one way).
Now for the split ticket sites:>
https://www.buytickets.scotrail.co.uk tells me that the price is £89.70.
https://www.traintickets.com/?/ tells me that it will cost £66.37 (with 4 tickets).
https://trainsplit.com comes up with a price of £66.38
So, both the multi split sites are much cheaper than Scotrail despite charging 15% commission on the amount saved on the through ticket price. (These fares gathered at 7.30am UK time on 11 February so could vary in time).
Remember - all the above prices are for using exactly the same trains on the same date/timings. You could be paying £44.63 more by using the actual train company site or www.nationalrail.co.uk - buyer beware!
