It's an important matter to be reported in local newspapers.
From what I've read in these forums, Northern & Merseyrail are relentless in their pursuit of non-fare payers. It's not hard to see the terrible consequences for an individual who didn't pay for this journey (perhaps through shock at the bizarre fare) as it was pursued through the courts/
I understand and agree with the sentiment, but is really hard to see that ever happening in this example. Rainford has no ticket office or machine so anyone making that journey would pay the guard, who'd realise something was very wrong. Likewise if you tried to buy it at another ticket office, it would be noticed.
The only way I can think of this ticket possibly being bought is at a machine if the buyer doesn't notice the price (will machines sell tickets that expensive? I've no idea) - which also means buying it from a machine which lets you choose a different origin station, which are rare.
I think it's safe to say no-one's ever bought it and was never likely to. Yeah of course mistakes should be fixed, but this is no massive scandal, surely.
