The Iron Horse Regional Trail follows the historic right-of-way of the Southern Pacific Railroad's San Ramon Branch Line, which was established in 1891. This railway played a crucial role in the development of central Contra Costa County, facilitating the transport of agricultural products and connecting communities. Passenger service eventually ceased in 1934, and by the late 1970s, the line fell into disuse and was abandoned by Southern Pacific in 1977. Recognizing its potential as a transportation corridor, Alameda and Contra Costa Counties purchased the right-of-way between 1983 and 1989. The East Bay Regional Park District had already identified the route as a priority for a future trail in its 1976 Master Plan. Through the combined efforts of local community groups, such as the Right of Way Trail Advocates, and government agencies, the Iron Horse Trail was first established in 1986. Over the years, the trail has been incrementally extended and improved, with significant segments opening in 2008 and 2014, and plans to eventually span over 50 miles, connecting 12 cities from Livermore to Suisun Bay.
