Two Amtrak train cars detached while the train was reportedly going 125 mph

  • An Amtrak train travelling from Washington, D.C., to Boston broke apart while reportedly moving at 125 mph.
  • Amtrak said the incident resulted from a “mechanical issue.”
  • The incident follows three accidents involving Amtrak trains since December.

Two cars on Amtrak Acela Express train 2150 separated while travelling from Washington, D.C., to Boston on Tuesday morning, Amtrak told Business Insider. The incident occurred at around 6:40 a.m. and resulted from a “mechanical issue,” though no additional details were provided about the accident’s cause.

The train was carrying around 52 passengers who were transferred to another train. No injuries have been reported.

The New York Post first reported the accident and stated that the train was travelling to New York from DC. The Post also reported that the train was reportedly moving at 125 mph at the time of the accident, but Amtrak declined to comment on the speed.

This incident follows a string of Amtrak accidents in recent months, beginning with the January 18 derailment in Washington state that killed three passengers and injured 62 passengers and crew members after the train was moving 78 mph in a 30 mph zone during its first trip on a new route.

On January 3, three cars derailed in Savannah, Georgia, on an Amtrak train travelling from Miami to New York. And on Sunday, two passengers were killed and over 100 were injured when a passenger train crashed into a stationary freight train in Cayce, South Carolina.

The accidents in Washington and South Carolina occurred on trains that were not able to use positive train control (PTC), a technology that can send warnings to trains or automatically stop them if it senses a dangerous situation approaching. While Congress mandated that all Class 1 railroad mainlines in the US, like those used for passenger service, be equipped with PTC by the end of 2015, the deadline was later pushed back to the end of 2018 with the chance for another two-year extension.

It is not clear if Acela Express train 2150 was equipped with PTC, or if PTC could have prevented the accident. An Amtrak spokesperson told Business Insider that the company is currently investigating the incident.
