Something moving underground

A good thing about starting this 'photo a day' thing is that it forces me to pay attention. On a usual day like today, when I'm tired and fuzzy and my head feels stuffed with asbestos, I would have hardly lifted my head the whole walk to and from work. The challenge to get a half decent photo forces my chin up, my eyes open to possible shots and my head ignoring the normal internal running commentary. It makes me take notice and really I don't do that enough, caught up with my own wee heart storms mair often than not.
So this morning I waited and got this nice image of the subway train arriving at Partick. Something is moving underground, and I think I like it.
