Public transportation is a marvel of modern technology and a boon to city life. But if you’ve ever stood on a subway platform for a half an hour, you know there are caveats. For the people of Stockholm, you can add “haunted” and “will teleport you to another dimension” to the list of potential train complaints.
The Swedish legend of Silverpilen (or "Silver Arrow") goes back to the 1960s, when the Stockholm Metro purchased eight trains made out of aluminum. The material was standard enough for the time, but most Stockholm Metro cars were painted green. The transit authorities decided to leave these bare, which made them stand out from the rest of the cars. That wasn't the only thing that made the trains seem unusual: the interiors were laid out a little differently, and were missing the usual graffiti and advertisements. Soon, a legend was born: for Stockholm's commuters, any component of public infrastructure so pure—so unblemished—must have been a ghost.
Of course, any good ghost train needs a ghost train station. According to legend, the train’s destination was an equally unsettling, totally abandoned station known as Kymlinge. In Stockholm there’s a saying that loosely translates to: "Only the dead get off at Kymlinge." As the corresponding story goes, once you board the Silver Arrow, you never get off. Not because you get murdered, but because the train gets stuck in some kind of time loop and rides on for eternity.
In another version of the legend, the train does stop eventually, but only once a year. At that point, all the passengers have been on the train for so long that they appear to be among the undead, and are unleashed on the city in some kind of scenario out of The Walking Dead.
The truth of Silverpilen, and Kymlinge, is perhaps more interesting: The city of Stockholm was running the stripped-down train as a test. If the public didn't seem bothered by the bare-bones trains, the local transportation agency figured they would be free to construct a cheaper fleet.
But the people of Sweden thought the Silver Arrow—a nickname that seems to have popped up soon after the trains were introduced—looked derelict, and frankly downright dystopian. The creepiness factor was such that even if the train was running and relatively empty compared to a grimy, old, familiar green train, Stockholm locals avoided it. So while the metro used the trains as backups during rush hour for several decades, they were never very popular.
As for Kymlinge, construction on the station began just a few years after the so-called Silver Arrow started running. It was never finished, because the expected demand for the station, tied to a nearby redevelopment project, never arrived. The bare look of the station must have reminded people of Silverpilen—or people just figured if you come across an abandoned, half-finished subway station, and you already have a creepy ghost train, you’re going to pair them up.
What’s so wonderful about the story of Silverpilen is that, unlike many urban legends, all the major pieces are real: there really is a silver train and a never-finished abandoned subway station. In fact, the cars of the Silver Arrow train weren’t decommissioned until the 1990s. Despite the fact that the train hasn’t been seen on the tracks for generations, the legend has been passed down, and younger generations of Swedes still whisper about its ghostly presence.
And there's still at least one place the out-of-service cars can be seen: at the Stockholm Police Academy. They’re used to train rookie cops on how to deal with in-process crimes on metro trains—though we're guessing that training does not include ghostbusting.
