I meant to mention this a while ago, but it slipped my mind. A while back, I had to get a replacement annual season ticket, as the print on mine was getting close to illegible. When I went in to the Southern ticket office, they could not find the details of my season ticket - which I found strange. The bloke behind the counter asked if I bought it online from Southern, which I did. According to him, the system they use at railway stations is not able to see the details of season tickets purchased online. Does anyone know why this is? Is it just a case of Southern not investing in decent software?
