This article is about the 2008 Metrolink train collision in Los Angeles, for the 1887 train collision at Great Chatsworth, Illinois, see 1887 Great Chatsworth train wreck.

The 2008 Chatsworth train collision occurred at 16:22 PDT (23:22 UTC) on Friday September 12, 2008, when a Union Pacific freight train and a Metrolink commuter train collided head-on in the Chatsworthmarker district of Los Angelesmarker, Californiamarker, in the United States. The scene of the accident was a curved section of single track on the Metrolink Ventura County Line just east of Stoney Pointmarker.

Before the collision, the Metrolink train may have run 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 Metrolink train's engineer was near the end of a work week of long split shifts, making fatigue a subject of the investigation, along with distraction from text messages he was sending while on duty. The accident remains under investigation; meanwhile the basic circumstances have been released to the public, but the official report determining probable cause is expected to take up to a year to complete.

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. With 25 deaths, this became the deadliest accident in Metrolink's history. Many survivors remained hospitalized for an extended period. Lawyers quickly began filing claims against Metrolink, and in total, they are expected to exceed a US$200 million liability limit set in 1997, portending the first legal challenges to that law. Issues surrounding this accident have also initiated and reinvigorated public debate on a range of topics including public relations, safety, and emergency management, which has also resulted in regulatory and legislative actions.

Collision

Metrolink commuter train 111, consisting of a EMD F59PH locomotive (SCAX 855) pulling three Bombardier BiLevel Coaches, departed Union Stationmarker in downtown Los Angelesmarker at 15:35 PDT (22:35 UTC) heading westbound to Moorparkmarker in suburban Ventura Countymarker. Approximately 40 minutes later, it departed the Chatsworth stationmarker with 222 people aboard, and had traveled approximately when it collided head-on with an eastbound Union Pacific local freight train. The freight train was led by two SD70ACe locomotives, UP 8485 and 8491, weighing more than each. The Metrolink locomotive telescoped into the passenger compartment of the first passenger car and caught fire. All three locomotives, the leading Metrolink passenger car and seven freight cars, were derailed, and both lead locomotives and the passenger car fell over.

The collision occurred after the 46-year-old Metrolink passenger train engineer Robert M. Sanchez apparently failed to obey a red, stop signal that indicated it was not safe to proceed into the single track section. The train dispatcher's computer at a remote control center in Pomonamarker did not display a warning prior to the accident according to the National Transportation Safety Board (NTSB). Metrolink initially reported that the dispatcher tried in vain to contact the train crew to warn them; but the NTSB contradicted this report, saying the dispatcher noticed a problem only after the accident, and was notified by the passenger train's conductor first.

Both trains were moving toward each other at the time of the collision. At least one passenger on the Metrolink train reported seeing the freight train moments before impact, coming around the curve. The conductor of the passenger train, who was in the rear car and was injured in the accident, estimated that his train was traveling at before it suddenly came to a dead stop after the collision. The NTSB reported that it was traveling at . The freight was traveling at approximately the same speed after its engineer triggered the emergency air brake only two seconds before impact, while the Metrolink engineer never applied the brakes on his train.

Location

The accident occurred after the freight train emerged from the 500-foot-long (150-meter-long) tunnel #28, just south of California State Route 118 near the intersection of Heather Lee Lane and Andora Avenue near Chatsworth Hills Academy. The accident was in Chatsworthmarker, a neighborhood of Los Angeles located at the western edge of the San Fernando Valleymarker. The trains collided on the Metrolink Ventura County Line, part of the Montalvo Cutoff, opened by the Southern Pacific Company on March 20, 1904, to improve the alignment of its Coast Line. Metrolink has operated the line since purchasing it in the 1990s from Southern Pacific (now owned by Union Pacific), which retained trackage rights for freight service.

Railroad physical characteristics

Both trains were on the same section of single track that runs between the Chatsworth stationmarker (which is double tracked) through the Santa Susana Passmarker. The line returns to double track again as it enters the Simi Valley. Three tunnels under the pass are only wide enough to support a single track, and it would be very costly to widen them. This single track section carries 24 passenger trains and 12 freight trains each day.

The line's railway signaling system is designed to ensure that trains wait on the double track section while a train is proceeding in the other direction on the single track. The signal system was upgraded in the 1990s to support Metrolink commuter rail services, and Richard Stanger, the executive director of Metrolink in its early years of 1991 to 1998, said the system had functioned without trouble in the past. The Metrolink train would normally wait in the Chatsworth station for the daily Union Pacific freight train to pass before proceeding, unless the freight train was already waiting for it at Chatsworth.

Aftermath

Emergency response

The Los Angeles Fire Department (LAFD) originally dispatched a single engine company with a four person crew for a "possible physical rescue" at a residential address near the scene in response to a 9-1-1 emergency call from the home. The crew arrived at the address four minutes later, just before 16:30 PDT and accessed the scene by cutting through the backyard fence. Upon arrival, the captain on the scene immediately called for an additional five ambulances, then 30 fire engines, and after reaching the wreck he called for every heavy search and rescue unit in the city. Hundreds of emergency workers were eventually involved in the rescue and recovery efforts, including 250 firefighters.

The event was operationally identified as the "Chatsworth Incident" and was reclassified as a "mass casualty incident." All six of LAFD's air ambulances were mobilized, along with six additional helicopters from the Los Angeles County Fire Department and the Los Angeles County Sheriff's Department. The helicopters were requested under a mutual aid arrangement.A review of the emergency response and the on-site and hospital care was initiated by the Los Angeles County Supervisor immediately after the event, and is expected to take 90 days to complete.

Casualties

Recovery workers stand near the rear of the Metrolink locomotive after it was removed from the lead passenger car, where most of the serious injuries and deaths occurred.


, 25 people have died, including two victims who had died at hospitals in the days following the crash. This became the deadliest railway accident in Metrolink's history, and the worst in the United States since the Big Bayou Canot train disastermarker in 1993.


A total of 135 others were reported injured, 46 of them critically, with 85 of the injured transported to 13 hospitals and two transported themselves. Air ambulance helicopters medevaced 40 patients. LAFD Captain Steve Ruda reported that the high number of critically injured passengers taxed the area's emergency response capabilities, and patients were distributed to all 12 trauma centers in Los Angeles County. Providence Holy Cross Medical Center in Mission Hillsmarker treated 17 patients, more than any other hospital.

Captain Ruda said his firefighters had never seen such carnage. Austin Walbridge, a train passenger, told a TV news reporter that the interior of the train was "bloody, a mess. Just a disaster. It was horrible." Emergency responders described the victims as having crush type injuries. Dr. Amal K. Obaid, a trauma surgeon who practices at USC University Hospitalmarker where several victims were treated, described their injuries in more detail, "They have head injuries, multiple facial fractures, chest trauma, collapsed lungs, rib fractures, pelvic fractures, leg and arm fractures, cuts in the skin and soft tissue. Some have blood in the brain."

The Los Angeles County Coronermarker set up an air-conditioned tent that functioned as a temporary morgue at the site. One off-duty Los Angeles Police Department officer was among the confirmed deaths, as was the Metrolink train's engineer,an employee of Veolia Transportation, a contracted operator of Metrolink.One of the passengers who died was a survivor of the 2005 Glendale train crashmarker.Another had been commuting by train since Metrolink's inception in 1992.Many victims were residents of suburban Simi Valley and Moorpark on their way home from work in the Los Angeles area.

The four other crew members of the two trains survived.The conductor and engineer of the freight train were trapped inside the lead locomotive while it was engulfed in flames; the firefighters who rescued the pair found them banging on the thick glass windshield, unable to escape. The freight crew also had a brakeman riding in the second locomotive who was injured in the crash.

The search for victims came to an end shortly after 14:30 PDT on September 13, approximately 22 hours after the collision.

Service disruptions

The crash disrupted service on the Pacific Surfliner and the Coast Starlight. Amtrak canceled service on the Pacific Surfliner between San Luis Obispomarker and Union Station in Los Angeles and Thruway Motorcoach buses transported Coast Starlight passengers from Union Station to Santa Barbaramarker to board the trains. Metrolink service on the Ventura County Line was interrupted north of Chatsworth, and all service resumed four days after the accident.

Investigation

Preliminary investigation controversy

Metrolink spokeswoman Denise Tyrrell disclosed the day after the crash that a preliminary investigation of dispatch records and computers showed the engineer of the Metrolink passenger train failed to stop his train for a red railway signal, which indicated his train did not have permission to proceed. She was quoted as saying, "We don't know how the error happened, but this is what we believe happened. We believe it was our engineer who failed to stop at the signal." Tyrrell said that if the engineer obeyed the signal, the accident would not have occurred. However Los Angeles County Supervisor and Metrolink board member Don Knabe said it was premature to blame the engineer, speculating that "there could always be a technical malfunction where... there was a green light both ways." A professor of industrial engineering and systems engineering at the University of Southern Californiamarker also argued against blaming the engineer, saying that the investigation would need to determine why the engineer passed the signal and how backup systems failed to prevent the crash.

After a Metrolink board meeting two days after her remarks, Tyrrell resigned. Tyrrell stated that she quit because a Metrolink Board statement called her announcement premature, and inappropriate; she maintained that it was proper to get out in front of the story before the National Transportation Safety Board (NTSB) took over the investigation. She stated that she asked for and received authorization to make the comments from David Solow, Metrolink's chief executive. Solow confirmed that he did give authorization, but said in hindsight he would not have given permission. After her resignation, some good government proponents praised Tyrrell for her candor, including the chief public advocate with California Common Cause. The Los Angeles Times also published an editoral by columnist Patt Morrison sympathetic to Tyrrell's position, in which she says, "I am unclear of the concept of how the truth can somehow be premature. The truth is the truth."

Official investigations

The NTSB is leading the official investigation to determine the probable cause, but NTSB officials had not commented on the accident prior to the Metrolink statement. In a subsequent press conference at the scene two hours after Tyrrell's comments, an NTSB official cautioned that the cause of the accident is still under investigation. The NTSB studied the data from the train event recorders, which had been recovered by NTSB investigators working at the scene. The Metrolink train had two data recorders, one badly damaged, and the freight train had a data and a video recorder. The NTSB said it would collect other evidence and interview witnesses to try to officially report within a year's time why the crash occurred.

Tests of the railway signal system after the accident showed it was working properly, and should have shown proper signal indications to the Metrolink train, with two yellow signals as the train approached the Chatsworth station, and a red signal at the switch north of the station. "We can say with confidence that the signal system was working," the lead NTSB board member stated at a news conference after the tests. This focused the NTSB investigation on human factors. However three witnesses later came forward to say that they observed the signal to be green as the Metrolink train departed the Chatsworth station just before the collision. A newspaper reporter interviewed the witnesses at the station, and confirmed that the signal was visible from the station, and that the witnesses could correctly identify the colors displayed. The NTSB declined to comment on the witness statements, but a safety consultant said that although this type of signal failure is extremely rare, he had seen it twice before in his 13 year career as a locomotive engineer.

Before releasing the accident scene and allowing restoration of service, the NTSB also conducted a final sight distance test. An identical Metrolink train and pair of Union Pacific locomotives were brought together at the point of impact and slowly backed away from each other. The test showed that the trains' engineers could not see each other until less than five seconds before the collision.

The surviving crew members could not be interviewed by the NTSB immediately after the accident because they were still recovering from their injuries. The NTSB was able to interview the Metrolink conductor about recorded radio communications, which did not capture the required communication between the conductor and engineer on the aspects displayed by the last two signals the train passed before the accident. He confirmed they did not call out the last two signals.

The NTSB also stated that a railroad switch showed evidence of damage consistent with the Metrolink passenger train "running through" the trailing switch points while they were set to allow the freight train to proceed onto the adjacent track, forcing them out of the way. "The switch bars were bent like a banana. It should be perfectly straight," according to the NTSB official. The NTSB member in charge of the investigative team said they were also concerned with possible fatigue issues related to the engineer's split shift. The engineer worked an 11.5-hour shift split with a 3.5-hour break, leaving only nine hours away from work between workdays.

The Federal Railroad Administration (FRA) is also investigating to determine if any federal safety regulations were violated. The California Public Utilities Commission, the state agency responsible for regulating railroads, also reported that it has ten investigators with railroad experience working in conjunction with the NTSB, and will also be looking into the matter of the Tyrrell resignation.

Text messaging



Local television news broke the story that the Metrolink engineer was exchanging brief text messages with a teenage train enthusiast while operating the train, a violation of Metrolink rules according to the agency. The last message received from the engineer, time-stamped one minute before the collision, reportedly said, "yea ... usually @ north camarillo," apparently a reference to a town further down the line where the engineer expected to meet another train.

The NTSB did not recover the engineer's cellphone in the wreckage and said the teens were cooperating with the investigation, initially noting that similar rumors about an engineer using a cell phone from an investigation recently conducted in Boston were unfounded. After receiving the engineer's cell phone records under subpoena, the NTSB confirmed that engineer was texting while on duty, but had not yet correlated the messages with the accident timeline. After completing a preliminary timeline, the NTSB placed the last text message sent by the engineer at 22 seconds before impact.

An NTSB representative refused to comment further on the preliminary timeline, which investigators were still refining. Two University of Southern California academics used the information in the NTSB statement to determine that the last text message sent by the Metrolink train's engineer would have been sent a few seconds after he had passed the last red signal. This would make unconsciousness an unlikely cause for this error, since the engineer was able to compose and send the message; instead a psychology professor from the University of Utahmarker raised the possibility that "inattention blindness" caused the engineer to fail to see the signal.

The day after the NTSB confirmed the engineer was texting, and less than one week after the accident, the California Public Utilities Commission unanimously passed an emergency order to temporarily ban the use of cellular communication devices by train crew members, citing this accident and a previous San Francisco Municipal Railway accident where the train operator was using a cell phone.A week later, texting while driving an automobile was outlawed in California, effective January 1, 2009.

There was no federal regulation prohibiting cell phone use by train crews at the time of the accident, but the NTSB had recommended the Federal Railroad Administration address the issue in 2003, after concluding cell phone use by a freight train engineer contributed to a fatal head-on train collision in Texasmarker in 2002. However, 19 days after the accident the FRA administrator issued Emergency Order No. 26 restricting the use of "personal electronic or electrical devices" by railroad operating employees.

On March 3, 2009 federal investigators released records showing that the train engineer Robert M. Sanchez had allowed a train enthusiast to ride in the cab several days before the crash, and that he was planning to let him run the train between four stations on the evening of the crash. "I'm gonna do all the radio talkin' ... ur [sic] gonna run the locomotive & I'm gonna tell u [sic] how to do it," Sanchez wrote in one text. Records also show Sanchez had received two prior warnings from his supervisors about improper use of cellphones while in the control cab.

Conductor's role

The operating rules for trains with a sole driver is that all signals are to be reported to the conductor. This allows the conductor to pull the tail (apply the brakes) should the driver appear to be incapacitated for any reason. However, in this incident, according to the data video, the last two signals were not reported, nor did the conductor apply the brakes.

Positive train control

Officials, experts, and litigators have injected the example of this accident into the discussions around deployment of positive train control (PTC), a safety backup system that can automatically stop a train. Federal Railroad Administrator Joseph H. Boardman told a reporter days after the accident that PTC "would have stopped the train before there was a collision." The National Transportation Safety Board (NTSB) member leading the investigation also said she was convinced that such a system "would have prevented this accident." These systems are not widely deployed yet, and would require a multi-billion US dollar investment to reach that goal nationwide. A Metrolink board member acknowledged they were studying this technology, but said that press reports implying that PTC systems were available off the shelf are misleading, and denied that cost was the primary reason it has not been deployed there. PTC has been on the NTSB's most wanted safety improvements list since 2001.

At the next regularly scheduled Metrolink board meeting after the accident, the board decided not to wait for PTC to be ready for deployment before making system safety improvements; instead Metrolink will expand the existing automated train stop system used on of Metrolink track in Orange Countymarker across its system. Metrolink's automated train stop system will automatically apply the brakes to stop a train if the engineer fails to respond to a warning within eight seconds. It was originally installed in the 1950s by the Santa Fe Railroad to allow trains to operate at speeds of over 79 mph under regulations imposed by the Interstate Commerce Commission, a former federal regulatory body whose safety functions have since been assumed by the Federal Railroad Administration. Metrolink is also adding a second engineer to some trains to improve safety.

Litigation

On September 15, 2008, the family of a 19-year-old killed in the crash announced they had filed a claim with Metrolink, generally a precursor to a lawsuit, "alleging the agency chose not to use the available rail safety features," referring to positive train control which they say would have averted the disaster. Eleven days later, an attorney representing the brakeman of the freight train announced a lawsuit against Metrolink, which also named Veolia Transportation and its subsidiary, Connex Railroad, the Metrolink engineer's employer, as defendants. The claim they filed against Metrolink and Veolia was denied, allowing them to proceed with the lawsuit. The lawyer asserted that the Metrolink engineer "was asleep at the switch and not paying attention to what was going on around him..." and that Metrolink "allowed a dangerous, defective and unsafe condition to exist."

An issue likely to come into play will be a provision in the Amtrak Reform and Accountability Act of 1997 (P.L. 105-134), which places a US$200 million cap on the aggregate of all passengers' damage claims in a railroad accident against a passenger railroad, including punitive damages. Bloomberg News reported that this event would likely be the first legal test of this law, according to a former House rail committee staffer who helped write the law, who predicted that given the number of casualties, the cap is almost certainly going to be an issue in pending litigation. An attorney representing two of the victims agreed, saying payouts could range from $5 million to $10 million per death or serious injury. Metrolink reportedly has insurance coverage totaling $150 million.

California has a six-month deadline for filing legal actions after an accident, so time was of the essence for plaintiffs as well as their legal advocates. However, the aggressive tactics of some lawyers led the State Bar of California to publicly warn its members that unsolicited contact with a potential client is both illegal and unethical.

Other railroads

In response to this event, other commuter railroads made statements to reassure their passengers of the safety of their operations, and these responses provided some perspective on how other operators mitigate related risks. A spokesman for the nation's largest commuter rail operation, the Long Island Rail Road in New Yorkmarker, said that it had studied positive train control, but decided to stick with its "automatic speed control system," a form of cab signaling with automatic train stop using technology that is more than 50 years old. The San Diegomarker's Coaster commuter line also has an automatic train stop system that a spokesman said will stop the train automatically if the engineer fails to stop at a red stop signal.

Bostonmarker's MBTA says its "Cab Signal with Positive Stop" system can stop a train that passes a stop signal or when another train is in its path; the system averted disaster in March 2008 when it stopped a train heading for a runaway freight car. Southeastern Pennsylvania Transportation Authority has Automatic Train Control on 80% of its system, and will install it in the other 20% by 2014.

The Denvermarker area Regional Transportation District said that its FasTracks commuter rail program has been designed to limit exposure to freight traffic by using physical separation with separate freight and passenger tracks where possible and using temporal separation by running passenger trains during the day, and freight at night and between rush hours. The San Jose Mercury News reported that San Francisco Bay Areamarker Caltrain commuters are much less likely to be in a head-on collision because opposing trains usually run on separate tracks, and runs freight only at night on a large portion of its route. The North County Transit District's spokesman for its Sprinter service in San Diego also said it runs freight only at night when passenger service is suspended.

Memorials

Following the collision a temporary, spontaneous memorial of flowers and notes was erected at the Simi Valley Amtrak/Metrolink Stationmarker. On September 8, 2009, the first permanent memorial, a plaque, was placed in Union Stationmarker. The Metrolink Memorial Plaza was dedicated on September 12, 2009 at the Simi Valley station. The plaza features 11 columns, one each for the ten deceased passengers from Simi Valley and an additional one for the 14 other deceased victims. There are also 25 markers on the grounds to commemorate each victim as well as a seating area and a plaque in remembrance to the 2005 Glendale train crashmarker. Two days later, on the one-year anniversary of the crash a memorial ceremony was held at Stony Point Park, near the location of the collision.
