This is a painting of a Tube train stopped in Tower Hill station in London, UK. We passed through this station in 2016, as millions of tourists do each year, on our way to visit the Tower of London.

The Tube (aka the London Underground) is a showcase of public transit by most standards, with 11 lines serving 272 stations and 5 million people every day. This train was painted in the striking blue and red colours of their famous logo.
