As usual a visit to Westminster station has me reaching for my camera, my shutter finger twitching. This time I'm pointing up at the ceiling as I find the dark, smooth, curved concrete, the metal pipes and struts catching the light, in fact the entire industrial grandeur of the place very appealing to photograph. In the vast hall you get the interplay of the austere shiny, cross-bracing structures intersecting the open escalators all stacked on top of one another. The passengers travelling up and down briefly disappear as the criss-cross lines cast their shadows and I see it all in black & white. Compared to the vast majority of stations, Westminster is like a cathedral to tube travel.
