Regular visitors to Travel Between The Pages are well aware of my public transit fandom. Although I grew up riding the New York City subways, I never appreciated how good an urban rail system could be until I spent four months riding the rails throughout Europe.  The Subways of Europe  website is a celebration of those cities that have “a picturesque as well as historically interesting underground transportation network to explore”. The images favor a very much architectural style – empty of people but beautifully-lit, and focusing on stonework and tiling and atria and all that sort of thing. Even if you are not the type to geek-out over public transit, the website is worth a browse.
