        Trams run on 600 volt direct current. Feeder stations transform
        10,000 volt grid current into suitable direct current. There are 14 feeder stations in
        Helsinki. In 1998 trams consumed about 21 million kilowatts of electricity in Helsinki.  | 
       
     
      A switch iron has been an important tool for
    drivers since the beginning of tram services and will no doubt have uses in the future as
    well.  
      
     
     
     
     
     
     
    
      
        | The people of Helsinki have many names for trams. The proper
        Finnish term is "raitiovaunu", but this has been shortened to
        "ratikka" and "raitsika". Other nicknames include "skuru"
        and "spora". In the 1970s drivers gave four-axle trams the nickname
        "laihialainen", which is a synonym for cheap.  | 
        When conductors work was reduced, conductors booths
        were removed from trams. They became stripped-down models and hence the nickname.
        Drivers nickname for articulated trams is "nivel", which comes from the
        Finnish term for articulated, or "sarana", which means hinge.  |
