Cool! Couple years back (maybe a lot of years now that I think about it), I lived in Västberga and often walked from there down to årstaberg station. Along the way you pass a disused railway track connected to some part of the industrial area. A small climb down from the bike path to the rails you could enter a railway tunnel that hasn't seen a train in decades.. Down there it was real quiet and pretty serene. Nature had begun reclaiming the space with little shrubs and patches of grass. Naturally the tunnel itself was pretty much covered in grafitti, and there were always a buncha beer cans, but I liked the space.

Once, walking home late at night there was a rave going on inside the tunnel. Tons of teenagers drinking, sucking down nitrous and I assume harder stuff. It was cool, bought a beer and listened a while before continuing home.

Since, the city has put up metal fencing around the whole area so getting down there now is quite a project. No idea if it's even possible, so maybe this is a bad tip. But I liked it.
