Malmi station in Helsinki, with a local train consisting of Dm7 railbuses stopping. This third Malmi station was opened in 1934 (we had a habit on building too small station buildings to save money, which resulted in them being replaced by larger ones at regular intervals) and remained in use until a new station was opened in 1986 about 200 metres north of this one as a part of developing a new local center for Malmi (the station is flanked by two shopping malls). The third station building remains in existance today, and is a protected building.
One of the interesting results of modern technology is the station building becoming useless. Even small suburban stations like Malmi used to be staffed by dozens of people, not only those selling tickets and serving cargo (until the mid-20th century every train station was also a freight station), but those engaged in the actual coordination of the trains; before computers you needed people to coordinate with other stations to make sure trains run on time, that trains are not accidentally allowed on the same track... even points were hand-operated. All these things are now automated, or coordinated from a central control center, and thus the station building is reduced to just a shelter for passengers with maybe a cafeteria or kiosk.
