RailGiants Train Museum Hours

RailGiants is open on selected weekends and during 2022 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.

Metrolink Earthquake Operations
Miracle of Tunnel 25

The earthquake that struck Southern California at 4:30 am January 17th, 1994, was devastating by any measure. Loss of life and property was severe and deeply affected the people of the region. The collapse of the Iinterstate-5, State Hwy-14 freeway interchange bridge in Weldon Canyon presented a major transportation crisis. And there was simply no other rubber tire vehicle option through the mountains within miles. However, the 6,976-foot bore piercing the San Gabriel Mountains, known simply as tunnel number 25, also situated in Weldon Canyon on the former Southern Pacific’s Saugus line survived the 6.8 earthquake…unscathed.

As the result, Metrolink’s Santa Clarita Line would see operational and alignment changes of unprecedented levels to meet the immediate surge in ridership. Train lengths were expanded from the normal three cars up to eight cars and to as many as 11 cars with an F59PH locomotive placed at each end to assure sufficient power for the heavier consists. The Line was renamed Antelope Valley Line when service was extended within days of the quake through Soledad Canyon to Palmdale and Lancaster.

Harvey Laner resides in the area and immediately began making a video record of the events that followed the quake. This program covers the use of borrowed Amtrak F40PHs, San Francisco Bay Area's Caltrain eight-car gallery trainset consisting of seven trailers and one cab control car, the loan of 18 Go Transit commuter coaches and five GO Transit APCU power cars, former Ontario Northland and Milwaukee Road model FP7A's that had their EMD prime movers and traction motors removed and replaced with a Detroit Diesel HEP power plant.

This backdrop set the stage for what was one of the most ambitious railroad construction projects in modern time. With funding from FEMA, the Federal Emergency Management Administration in hand, work on realigning the rail line through Soledad Canyon took place at a feverish pace with the goal of converting it from a freight railroad to a commuter passenger railroad with a significant reduction in travel time. This documentary is a details-intensive program that follows the progress of the various realignment projects before, during and after from lineside and from the locomotive cab.
