Please can someone explain what a loophole is without giving any locations away? Is it like a fare that’s been accidentally priced for say £5 when it should be more like £30? Or are they less extreme than that?
One example that is now fixed is Denby Dale to Sheffield. An Anytime Day Single is £5.80, Anytime Day Return £8.50. Ticket machines and online journey planners used to allow you to use it via Manchester or Leeds on the last journey of the day on Sunday (without setting a via point), or all the time when you set a via point. I commuted on those tickets from Manchester to Sheffield for months, and only got questioned by a very overzealous TPE guard once (who I’ve had run-ins with since). He took my details but nothing came of it! It eventually got patched, but with a railcard being able to commute from Manchester to Sheffield for £5.60 isn’t to be sniffed at!
