The Economist:

EARLY this month, a massive new railway tunnel opened for the first time. It was finished six months early and nearly 10% under budget. So by now you know this didn’t happen in America (or Britain, for that matter.) No, this feat of modern engineering (and good government) was completed in the Swedish city of Malmö, just across the Oresund bridge from Copenhagen, Denmark.
The project transformed Malmö Central Station, which is actually in the northern part of the city, from a dead end where trains had to reverse course into a through station. The former terminus is now just a stop on a large circular route that cuts underground through the center of Sweden’s third-largest city. The construction of the tunnel was accompanied by the construction of two new stations–one in the actual city centre, and another south of the city, in an area targeted for future development. Here’s a map:
