The Morenci Loop is trestle bridge located between the San Francisco River and Morenci in Arizona, United States. Thomas, Nia and Ace crossed the bridge during their trip around the world and nearly accidentally collided with a diesel when they rolled back down the loop.



  • While the tracks are standard gauge and double tracked in the movie, the real life Morenci Loop was narrow gauge and single tracked.
  • Although depicted as operational in Thomas & Friends, in real life the loop was closed in 1922.
