My efforts this week to secure rail tickets on the Internet did not prove a signal success. Three times I typed in at laborious length my requirements and payment details. Three times the operation aborted at the final ‘get tickets’ stage of the procedure.

Or is this what had happened? When something similar occurred a couple of months ago I found when my credit card bill arrived that I had actually paid twice over.

That explained the great wodge of tickets that had been delivered to me from the automatic machine at Oxford railway station. First Great Western were very good about it, though, and offered a refund without quibble.

An acquaintance, who is about as computer-challenged as I am, went one better on his Internet ticket order. Minutes after he had completed the business, he received an email from FGW: did he really want a whole carriage with 60 seats?
