One Sketch 203) #inktober2018 prompt 14 - Clock

I've said it once, I've said it twice,
I'll say it once again,
You shouldn't underestimate
The power of the train.

Train, what's that got to do with it? Well, this is the exterior of St. Pancras station in my home city of London. I just felt it might be nice to use the clock prompt to illustrate the prompt - clock.
