RailGiants Train Museum Hours

RailGiants is open on selected weekends and during The Los Angeles County Fair

RailGiants Train Museum is open on the second full weekend of each month. Our hours of operation are from 10am until 5pm. RailGiants is located in the Los Angeles County Fairgrounds in Pomona, California. During our open house weekends at RailGiants, visitors can walk around all locomotives and railcars and buy train souvenirs in our RailGiants Store in the depot. By walking up stairways into each giant locomotive, you can see into the cabs where engineers and firemen operated these large engines down the tracks of the nation’s rail network. Visitors are welcome to join us while maintenance and rehabilitation work is in progress and ask our volunteer museum staff members any questions.

Admission to the RailGiants Train Museum is always free. During the Los Angeles County Fair event, RailGiants is part of The County Fair, and there is no additional cost to enter RailGiants after purchasing an admission ticket to The County Fair. Any donation to help maintain our equipment is optional, but always welcome. The excellent conditional of our historic railroad equipment is achieved by the generous donations of past visitors and the help of our volunteer members.

Please note: when the scheduled Sunday falls on Easter, the museum will be closed on that Sunday.

Check the Event Schedule page for our current schedule of days and hours.

If you need to make arrangements to see RailGiants Train Museum on a day when we are not normally open, or for filming for television and motion pictures, please send us a message on our Contact Us page, or call the Museum Depot on 909-623-0190.

Union Pacific’s Classic California Division Presented by Andrew Novak

Prior to the merger of Union Pacific (UP) and Western Pacific in 1982, UP’s California Division consisted of their main line from Las Vegas, Nevada to Los Angeles. This was originally the San Pedro, Los Angeles, and Salt Lake, also known as the Salt Lake Route. The program will start in Las Vegas and head west to Los Angeles along the main line. The program also covers UP branches in southern California such as the Anaheim Branch and San Pedro Branch. Also included are photos of select depots and some of the preserved UP equipment in southern California. The program includes freight, passenger, steam, and diesel; and the photos span from the 1950s to 2000s. If you are a UP fan, then this show is for you.

Andrew is editor of PRS’ newsletter, Wheel Clicks.
