RailGiants Train Museum at the Los Angeles County Fairgrounds in Pomona, California is a historical journey back to the glory days of the American Railroad.

Our Museum houses some of the country’s most well-preserved locomotives, which includes several sole survivors of their respective classes. Our RailGiants collection contains two of the four surviving 3-Cylinder steam locomotives; SP #5021 and UP #9000. The largest diesel locomotive, a Union Pacific “Centennial,” is also here. In addition to our locomotives, we have various pieces of Rolling Stock (freight and passenger cars), our historic Arcadia Depot, library archives, and gift shop.

We are open free to the public during the second weekend of each month, except in May, from 10 am to 5 pm. Ample parking is available.
