I was on a Leeds to Skipton train today. I boarded at Shipley with a Hellifield to Shipley return ticket. When I showed this ticket to the guard he asked "do you live in Hellifield?" I said that I didn't and that I was travelling onwards to Lancaster, showing him my ticket onwards to Lancaster. He then asked "do you live in Lancaster?" I didn't. I said that I didn't. He then did the usual scribble on my ticket and continued his rounds. Because I was slightly taken aback at the question, I hadn't fully processed everything in time to ask him what the reason was for asking the question. Is there a reason to ask these questions? Does it help with something railway-related which only insiders know about?
