The commuter train station in Huddinge in use when the movie was shot, with its scenes there, was torn down completely in 1986. The nostalgic value of the movie came to be even bigger when copyright issues made the movie largely unavailable from the mid 1990's until its final DVD release in December 2017.
The commuter trains stopping at the station in Huddinge, both the one Olsson arrives with, and the one Stickan is shown not being able to get off, are both headed in the direction into Stockholm, not out from town, as they should be. Persson is waiting for Stickan at the station of Tullinge, which was at this time the next station for trains headed out from Stockholm, on their way towards Södertälje. (In 1987, the suburb of Flemingsberg got its own station between Huddinge and Tullinge.)
