When blips go bad...

While I was dashing for my train to Polmont thought I'd grab a discrete blip (wasn't sure about the photography policy in Queen St station).

But what have we ended up with is indecision. I wasn't sure if I should centre the image on the platform, the canopy, the trains or the tunnel. In the end we ended up with... nothing. So this is another one to add to my "try again" pile.
