In autumn, extra care should be taken near tram tracks as the fallen leaves make the tracks slippery and lengthen the braking distance of trams. Fallen leaves crushed under the tram wheels leave an oily residue on the surface of the tracks making tram wheels slip.
Drivers, pedestrians and cyclists are advised to take this problem into consideration when moving about the town. Do not cross the street at the last minute if you see a tram coming.
The slippery tracks also make it difficult for the trams to keep to the timetables. The situation is the most difficult in areas where trees grow right next to the tracks, for example on Mäkelänkatu and Munkkiniemen puistotie.
