I think it is rude not to get a platform capture when heading for your train ;). I have taken this photo at Charing Cross tube station.

I completely removed all saturation from the photo except for the platform artwork as I found quite an interesting contrast between its colour and the monochrome of the rest of the photo. I welcome your thoughts. R
