Amtrak is working to ease the toll of the deadliest derailment in its history.
On Friday, Amtrak said it had received a record number of rail injuries.
The accident on Friday was the deadliest since the deadly derailment of an Amtrak train in 2012 that killed more than 50 people.
The new accident was also the worst in the Amtrak’s history, which is expected to rise to more than 4,300 deaths this year.
The derailment, which occurred about 9:30 a.m.
Friday, involved a freight train that was headed to Boston from Pittsburgh, a train that had been on a back-to-back route between the two cities.
That train was carrying more than 1,000 people and the locomotive had been inspected by the Transportation Safety Board, the federal agency that investigates accidents involving freight trains.
The train derailed about 4:45 a.ms. in the northern suburbs of Springfield, Illinois, near the Ohio River.
The passenger train was headed for Springfield from Pittsburgh and was not equipped with brakes or other systems that could have slowed it, according to Amtrak.
A crew member said that at one point, the train slowed and the passengers had to be separated from the train to get out.
There were no reports of injuries or fatalities, according the National Transportation Safety Data Center, a research and analytics organization.
A spokesman for the Federal Railroad Administration said that the NTSB has been notified of the incident and is currently reviewing the crash data.
Federal Railroad officials are conducting an investigation, spokesman Michael Smith said.
The NTSB said in a statement that the train was a “multi-unit, two-car locomotive” with “a capacity of 1,200 passengers and freight” and that it was inspected on March 7, 2016, by the Federal Railway Administration.
Federal authorities said the train had been “tested and certified for performance” by the agency on March 9, 2016.
The federal agency said in its statement that Amtrak “has been working with federal, state, and local authorities, as well as the National Railroad System, to determine the cause of the accident.”
It added that the Federal Rail Administration has been in communication with Amtrak and is “conducting a thorough investigation of the train incident.”
The NTSC said that its preliminary investigation found that Amtrak had been in violation of federal rules governing the operation of freight locomotives and “may have violated federal safety requirements.”
The agency is also conducting an “intensive investigation” of the circumstances surrounding the derailment.
Federal investigators are expected to release a preliminary report next week.
“The accident is under investigation and we will continue to cooperate with the NTSC as it continues its review,” Amtrak said in an email to CBS News.
The Federal Railroad Safety Administration said in the statement that it is working closely with Amtrak to determine what happened and to help improve the safety of freight train operators.
“In addition, Amtrak will implement a number of safety measures to ensure safety on our trains and to reduce the number of accidents and fatalities on our tracks,” it said.
“This investigation is ongoing.”
The derailments come as Amtrak struggles to contain rising passenger rail injuries and death rates.
Last year, Amtrak lost more than 500 employees and its passenger service fell from more than 5 million trips in 2011 to about 3.3 million trips last year, according a study by the National Association of Railroad Passengers.
The group said Amtrak’s service was plagued by delays, poor customer service and the growing use of cellphones on the trains.
“We know that Amtrak’s operations are being challenged by a number: the rise in the number and severity of Amtrak injuries, the growing popularity of cell phones, the rise of ride-sharing, and the changing behavior of passengers,” said the study, which was conducted for the American Public Transportation Association.
“Amtrak has made strides in recent years, but this is only the tip of the iceberg.”
Amtrak also faces a growing backlog of federal train safety violations.
The National Transportation Security Administration, which investigates rail safety violations, said in August that the agency had filed 6,500 safety violations involving 7,000 passenger trains between January and March of this year alone.
The agency also said that it had filed 1,600 safety violations in the first half of 2016, up from 890 violations in 2015.
Amtrak’s woes with the federal government have been worsened by the derailments and the federal investigation.
In a statement, Amtrak CEO Russ Brandon said that while Amtrak is fully cooperating with federal authorities and “we have a number safety procedures and procedures in place,” the company is still reviewing all the data.
“Safety is our top priority and we have made strides on that front,” he said.
Federal regulators said that Amtrak has not been cooperating with the agency in its investigation.
“There is a significant amount of work that needs to be done to determine exactly what happened,” said Mark Belsky, acting assistant secretary for Transportation and Infrastructure, at a news conference.
“I have serious concerns about Amtrak’s compliance with the safety laws and regulations
