I just saw this about the 2021 derailment in Montana. I would guess maintaining the tracks is difficult in that remote part of the country.

HELENA, Mont. (AP) — Poor track conditions that should have been flagged by a freight railroad company’s inspectors caused
the derailment of an Amtrak train in Montana that killed three people and injured 49 others in 2021, federal investigators said Thursday in a final report.
The poor track conditions included a worn rail, vertical track deflection, misalignment and instability in the rail bed, the report found. The NTSB said BNSF’s lack of action indicated “a shortcoming in its safety culture.”
Thursday’s finding follows what was revealed earlier this year in the agency’s
investigative documents. Investigators identified a deteriorating track based on video footage from three eastbound trains, including another Amtrak train, that traveled through the area in the hours before the westbound Amtrak train’s derailment.
The problem got worse as the trains traveled over the area before the crash, the report said.
An image from video captured by the derailed train showed a nearly 3-inch (23-centimeter) misalignment in the rails, the report said."
