The 2008 Chatsworth train collision occurred at 4:22:23 p.m. PDT (23:22:23 UTC) on September 12, 2008, when a Union Pacific Railroad freight train and a Metrolink commuter rail train collided head-on in the Chatsworth neighborhood of Los Angeles, California, United States. The scene of the accident was a curved section of single track on the Metrolink Ventura County Line just east of Stoney Point. According to the National Transportation Safety Board (NTSB), which investigated the cause of the collision, the Metrolink train ran through a red signal before entering a section of single track where the opposing freight train had been given the right of way by the train dispatcher. The NTSB blamed the Metrolink train's engineer, 46-year-old Robert M. Sanchez, for the collision, concluding that he was distracted by text messages he was sending while on duty. This mass casualty event brought a massive emergency response by both the city and county of Los Angeles, but the nature and extent of physical trauma taxed the available resources. First responding officer Tom Gustofson described the wreck as “beyond human description”. Response included California Emergency Mobile Patrol Search and Rescue (CEMP) as a first responding unit requested by Los Angeles Police Department (LAPD). With 25 deaths, this was the deadliest accident in Metrolink's history. Many survivors remained hospitalized for an extended period. Lawyers quickly began filing claims against Metrolink. The accident launched and reinvigorated public debate on a range of topics including public relations, emergency management, and safety, which has driven various regulatory and legislative actions, including the Rail Safety Improvement Act of 2008.

Stoney Point, also known as the Stoney Point Outcroppings or Chatsworth Formation, is a Los Angeles City park near the north end of Topanga Canyon Boulevard (State Route 27) in Chatsworth, Los Angeles, California, part of the city of Los Angeles.

Chatsworth is a suburban neighborhood in Los Angeles, California, in the San Fernando Valley. The area was home to Native Americans, who left caves containing rock art. Chatsworth was explored and colonized by the Spanish beginning in the 18th century. The land was part of a Spanish land grant, Rancho Ex-Mission San Fernando, in the 19th century, and after the United States took over the land following the Mexican–American War, it was the largest such grant in California. Chatsworth has seven public and eight private schools. There are large open-space and smaller recreational parks as well as a public library and a transportation center. Distinctive features are the former Chatsworth Reservoir and the Santa Susana Field Laboratory. The neighborhood has one of the lowest population densities in Los Angeles and a relatively high income level. Chatsworth is the home of the Iverson Movie Ranch, a 500-acre area which was the most filmed movie ranch in history, as more than 2,000 productions used it as a filming location.

Spahn Ranch, also known as the Spahn Movie Ranch, was a 55-acre (22.3 ha) movie ranch in Los Angeles, California. For a period it was used as a ranch, dairy farm and later movie set during the era of westerns. After a decline in use for filming by the 1950s, its owner George Spahn established a stable for renting horses for riding on the varied acres. It became known in the late 20th century as the primary headquarters of Charles Manson and his cult followers, the "Manson Family", for much of 1967 and 1968. They were notorious for the Tate-LaBianca murders of August 1969. The entrance to the historic ranch was originally at 12000 Santa Susana Pass Road (street numbers have since been changed) of the Simi Hills and Santa Susana Mountains above Chatsworth, California. It is no longer in use. After Spahn's death and a wildfire that destroyed the main ranch house and outbuildings, the land was incorporated into the Santa Susana Pass State Historic Park.

Browns Creek Bike Path is a Class I bike path that is “tucked away from the surrounding hustle and bustle” of the San Fernando Valley, “hugging the side” of the Browns Canyon Wash. The path begins at Lassen Street, just east of Chatsworth Metrolink Station, and ends just north of Rinaldi Street near Stoney Point Park. Browns Creek (sometimes called Brown’s Creek), a tributary of the Los Angeles River, offers “splendid views of the irregularly shaped Santa Susana mountains rising to the west.” One local writer observed, “What [the concrete-lined creek] lacks in scenery, it compensates for by providing the trail with an open, airy setting.” The route has been described as “very rustic” (for an urban bike path, of course). The wash passes through a neighborhood with equestrian zoning and “Opposite the bike route, in the west levee, a horse trail also follows the creek.” Domestic goats, roosters and ponies have also been seen along the path. At Chatsworth station, bicyclists can connect to the G Line Bikeway. The path is in close proximity to Chatsworth Park North and Chatsworth Park South (both operated by the City of Los Angeles Parks Department) and Chatsworth Nature Preserve. Both Chatsworth Parks, “excellent parks…[with] interesting hills and rock formations there, as well as pleasant shaded rest areas” are accessible from Valley Circle Road. Riders can create an approximately 6.3-mile (10.1 km) loop beginning at either end of the Browns Creek route, connecting to Valley Circle Road via either Chatsworth Street or Lassen Street.
