Just on the subject of ticket checks, are there particular marks that are made on tickets when checked? I have looked at the stamps that are used and they usually say what service it was e.g. stating with the company initials like VT (Virgin). But when they mark them they don;t put on a code usually just a 'scribble' or something else.
The reason I ask is because when I travelled to Leeds on a TPX 170 in August, the inspector wrote '158' on my ticket when he checked it which I found rather amusing.
