From Stickan not getting off the train in Huddinge due to his asthma or hay fever attack, arriving at the next station Tullinge, meeting Persson at the platform, and for Persson to drive from Tullinge to Huddinge to take action himself, takes no more than eight minutes, clearly shown on the same visible clock at the Huddinge platform when the train originally stops there, and when Persson has just arrived there. This is considerably faster than possible in real life, even today.

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.)
