  • Installing rails for tram tracks and overhead lines for power means a higher up-front cost than using buses which require no modifications to streets to begin operations.
  • Tram tracks can be hazardous for cyclists, as bikes, particularly those with narrow tyres, may get their wheels caught in the track grooves.[1] It is possible to close the grooves of the tracks on critical sections by rubber profiles that are pressed down by the wheelflanges of the passing tram but that cannot be lowered by the weight of a cyclist.[2] If not well-maintained, however, these lose their effectiveness over time.[citation needed]
  • When wet, tram tracks tend to become slippery and thus dangerous for bicycles and motorcycles, especially in traffic.[1][3] In some cases, even cars can be affected.[4]
