Not certain which forum to put this in. Based on other people's experiences, what do people think the chances are of a lost season ticket being handed in and if it is handed in to somewhere other than a train station, it being forwarded onto a train company? For example would TfL on the Underground or a bus company forward on lost tickets to rail companies or would they hang onto it. Saying that if a cleaner was sweeping up, would they notice a ticket wallet on the ground and if they did, investigate to see what it is? Is can't hurt to ring every possible lost property office where one might have been to see if they have it? I once lost a season ticket at Euston underground station. It was most likely be around the escalators. I never saw it again. I got a replacement from the station, minus an admin charge.
