I love these views, you get to see the London Underground tube trains coming out of the tunnels and going into them.
They give a small glimpse into the fantastic tunnels that are so deep, long and well built that they have lasted so long and should last for a long time to come.
I especially like how you can see the metal supports that hold the tunnels up and make them keep their tube tunnel shape.
