At London King's Cross Station. I was on my way to platform 0 to catch my train home to Norfolk. Yes, there really is a platform 0 which seems a bit strange to me but then King's Cross is known to Harry Potter fans for strangely numbered platforms.
The red Virgin train sitting under that roof caught my eye.
Wonderful shot! Love the leading lines (lots of those) the bright colors of the train, your POV, the lighting, that beautiful ceiling - well done! Fav.
