For 20 years I have travelled from Leicester to Barnstaple via Birmingham and returned 1-2 weeks later. The last time was 15/12/11. I always catch the 6:43 or 7:10am train from Leicester to connect with the 8:12am from Birmingham to Exeter. In December 2011 the return fare was about £102. Network Rail now say the same journey will cost me £211!
They are saying if I catch a later train (9:43am) it will cost £106 travelling off-peak. This was never the case previously.
Is anyone able to tell me if the off-peak rules/times for my journey have changed since December 2011 and/or where I might find more information.
You could always try booking Megatrain fares from Leicester to London St Pancras and from London Waterloo to Exeter Central or St David's. Fares start from £1.00 single (plus £0.50 booking fee per booking) and a wide range of departures are available. These fares are not generally available on a Sunday and limited on a Friday and at peak holiday times. No seat reservations are available, but as these tickets are only ever offered on lightly loaded trains, there should never a problem in geting a decent seat.
The website is megabus.com and you select the train option on the appropriate drop down menu for each city pair.
Fares go on sale 45 days ahead of departure, so it does mean that you would not be able to book outward and return at the same time (unless you are returning the same day) as by the time the returns go on sale, the cheapest outward fares will have increased well above the £1.00 lead in fare, of which only a few are ever available at this price. I am usually standing by my computer at 0001 hrs on the day they go on sale to ensure I bag a £1.00 fare.
You would need to allow reasonable time to cross between stations in London when selecting which services you travel on out and back.
In addition, there is the tube fare (£4.00+ at present) or bus fare each way (which is considerably cheaper than tube) across Central London to factor in, as well as the off peak return fare of £13.70 between Exeter and Barnstaple, but you will still be quids in overall compared to the quoted through XC fare of £106.00 or £211.00 return.
