Probably completely and absolutely wrong, but is the centre one Reading? That's what I thought when I first saw it...
(then again, I did get EXD» wrong in a previous message...)
Oh crumbs ... I had it down as Southampton Central but you have me worried that it's mislabelled - you could be right. Advise / comment from anyone who knows both Reading and Southampton would be appreciated.!
It doesn't really look too much like Southampton to me, but then I only pass through and rarely alight there. Southampton Central has one island in the centre with two lines on either side, that image looks like there are three lines and the island doesn't look very familiar. Perhaps a larger version would help?
