 In the 1950s, it was possible that some week's last train, carrying a heavy load of coal cargo, was pulled from Jätkäsaari to Pasila by two Vr3 engines, causing even the windows of Eduskuntatalo to shake and the chasm between the two parallel Rautatienkatu (Railway Street) streets to fill with black coal smoke.Even in the middle 1970s one could see the supervisor engine of the harbour in the middle of the Market Square going to fetch cargo cars from Katajanokka, or pushing a long line of cars over the Market Square turning bridge in either direction.The track did not have official stations or stops, because its main use was cargo traffic, passenger traffic was agreed separately each time, including a separate train sender; most of the time the place of agreement was in Katajanokka.
