I think it's about time the fares system had a major overhaul, don't you think?
East Coast (and their predecessors) ave been giving the fares on the East Coast route a major overhaul by making it prohibitely expensive to travel anywhere for a day trip on a walk-up ticket.
I'm sure the overhauls will continue, resulting in further fare increases.
Unless the Government stops rewarding people for travelling by car and penalising rail passengers, further increases are inevitable.
In the past 14 years, York-Doncaster has gone up from £5 to £18.60 for the cheapest day return fare. It's arguably better value to get the bus now, as that's only £5 return, though it does take a long time, but at around 1/4 of the cost, it's got to be worth considering. Of course the incentive is there for people to drive, and that is what most people with access to a car will do.
Thanks for the advice

Also, I notice that the fares data only goes up to NFM14. Looking around on the internet, I notice that we are now on NFM20. Does anyone know if the more recent fares data will be added to the website?
The person who owns that website is working on it.
I wonder why they scrapped the SSR and CDR tickets but reduced the price of the SVR?
This is how I perceive it, others may disagree...
Back in GNER days, the Saver Return/Off Peak Return (SVR) was unrestricted so that is the fare people got to return another day and you could travel at any time.
In NFM06, the Super Off Peak (SSR) was introduced at the price of the old SVR, but with added restrictions, and a new SVR introduced at a higher price for people who wanted to travel before 0930. The Anytime fare was mostly used simply as a 'penalty' for buying on board.
The Anytime fares rose to ludicrous levels, so EC reduced their Anytime fares to a level that is more consistent with what they were at a few years ago (but, comparing fares since privatisation, it's still a huge increase as the decrease is tiny compared to the increases!) and at the same time abolished the Off Peak Return. This means if you can't travel at the Super Off Peak time, you have to pay even more than what you would have paid for the Off Peak Return, but the ticket type you're issued with is an Anytime.
They've abolished the day return fares, to make you pay more, this is in line with Government policy to ensure that passengers, and especially those of us on the ECML, are priced off rail so that more people choose to travel by car, and those who have no choice but to travel by train end up paying through the nose, to reduce the tax burden on rich people who don't use public transport.
There's nothing surprising about these fares, it's a similar story in other areas as walk-up day return rail travel becomes increasingly unaffordable.
