Smallest subway

 The tiny alpine town of Serfaus, Austria, is home to the world’s smallest subway, the Dorfbahn. This 1,280-meter (about eight-tenths of a mile) underground funicular holds 270 people and is free to use. It was built in 1985 to transport skiers from a parking area at one end of the pedestrian-only village to the ski lifts at the other end.
