As Norfolk Southern’s CEO prepares to go before the Senate this week, the company released a six-point safety plan in response to last month’s derailment in East Palestine, Ohio.

The plan was based on the National Transportation Safety Board's initial findings, Norfolk Southern said. The company also had to respond to a derailment on Saturday in Springfield, Ohio, which temporarily prompted a “shelter-in-place” order for nearby residents.

"Reading the NTSB report makes it clear that meaningful safety improvements require a comprehensive industry effort that brings together railcar and tank car manufacturers, railcar owners and lessors, and the railroad companies," said Norfolk Southern President and CEO Alan H. Shaw. "We are eager to help drive that effort and we are not waiting to take action."

The train was carrying many hazardous materials, including vinyl chloride. Two days after the Feb. 3 derailment, state of Ohio officials ordered the town to evacuate as chemicals were burned to prevent an explosion.

The six points of the plan include:

- Enhance the hot bearing detector network
- Pilot next-generation hot bearing detectors
- Work with industry on practices for hot bearing detectors
- Deploy more acoustic bearing detectors
- Accelerate its Digital Train Inspection program
- Support a strong safety culture

According to the NTSB's report, as the train traveled, it passed through hot bearing detectors, which detect the train's bearing temperature. About 30 miles from the site of the derailment, a temperature of 34 degrees above ambient temperature was recorded. Ten miles out, that temperature increased to 103 degrees. Near the derailment's location, that temperature was up to 253 degrees above the ambient temperature.

It is considered critical when the temperature reaches 200 degrees above the ambient temperature. At 115 degrees, the NTSB says the train must come to a stop for an inspection.

Norfolk Southern noted that its crew "operated the train within the company's rules and operated the train below the track speed limit."

Three people are dead after an Amtrak train derailed in Montana on Saturday afternoon, the Liberty County Sheriff's office said in a statement to CNN.

Authorities would not speak on the number of injured or the extent of their injuries.A statement from the railway said five cars from Amtrak's Empire Builder train 7/27 derailed near Joplin, Montana, injuring an undisclosed number of passengers.

The incident occurred around 4 p.m. local time, the statement said. At the time, there were about 147 passengers and 13 crew members on board.

"Amtrak is working with the local authorities to transport injured passengers, and safely evacuate all other passengers," the statement added. "Additional details will be provided as available."

The Empire Builder travels between Chicago-St.Paul/Minneapolis-Spokane-Portland/Seattle, according to Amtrak's website, and offers passengers a chance to "experience the rugged splendor of the American West.

"Traveling between Chicago and the Pacific Northwest along major portions of the Lewis and Clark Trail, the mighty Empire Builder takes you on an exciting adventure through majestic wilderness, following in the footsteps of early pioneers," the website adds.
