  Trains Have Steel Wheels Made for Rails, Not Roads
  Trains run on steel wheels, which are smooth, hard, and narrow. These wheels are designed to fit precisely on steel tracks with very little friction. On a normal road:
  
  The wheels would slip and slide—there’s no grip.
  
  They would sink into potholes or cracks, since they are thin and can’t handle uneven ground.

  Trains don’t run on ordinary roads primarily because their steel wheels and the tracks they rely on are far more efficient for long-distance, heavy-load transportation than rubber tires on asphalt. Additionally, roads are not designed to withstand the immense weight of a train, and trains lack the steering mechanisms needed to navigate regular roadways.
