This is how I pictured, in my Harry Potter, Chronicles of Narnia filled brain, that a tube station would look like. I was so relieved when I finally found one that met the standards of my imagination. Ha! Not an easy task. Let's be honest.
One thing all the tubes have in common is the wall of hot sticky humidity that hits you as soon as you make it down to the trains. Blah! Even if it's cold outside, a couple of minutes underground and you'll be all hot and sticky in two minutes flat. Sometimes less than that.
