Fairplex Railroad Museum – Visiting (1015)

Fairplex Pomona’s historical train exhibit is the only place in the world to see both the largest steam engine and the largest diesel locomotive ever to ride the rails. The Union Pacific’s 594-ton “Big Boy” shares the spotlight with the Union Pacific Centennial DD40X diesel powered locomotive, which measures nearly 100 feet in length. The exhibit is open free of charge to the general public the second weekend of each month.
