The Carquinez Toy Train Museum (CTTOM) is the only O Gauge Three Rail permanent layout that is open to the public in the greater Bay Area. Starting in 2011, a dedicated group of toy train enthusiasts started CTTOM with the main purpose of promoting a hands-on appreciation and better understanding of the hobby, history, and operation of toy trains while maintaining and teaching a high standard of craftsmanship.
The Museum is located in the Odd Fellows Building at 645 Loring Avenue, Crocket, California. The upper room, which is approximately 40' x 40', will house the Semi-Hi Rail layout. When completed, the display will feature the latest toy train technology and will allow members and visitors to run several three-rail trains, new and old. Train operation also will employ wireless, hand-held cabs. Future displays will focus on the heritage of toy trains.
