Andreas Biedl

The history of a single class of Berlin U-Bahn cars, told with delightfully obsessive levels of detail by a historian who has clearly inhaled a lot of pre-war dust on his way through the archives of Berlin. There's a lot about yellow paint, a great deal more than you might have wanted to know about door handles, and even a paragraph or two on World War II and the Berlin Wall. Probably not a book many people will be rushing out to buy, but a gem in its own way.
