Final answer:

Rolling and static friction enable a train to move along the tracks smoothly and efficiently.


Explanation:

Rolling friction exists between the wheels of a train and the tracks as the train moves. This type of friction allows the train to move efficiently and effectively along the tracks. Static friction plays a crucial role as well, providing the necessary traction for the train to accelerate, pull uphill, or maintain constant speed by pushing the train forward on the tracks.
