OMAHA, Neb. (AP) — BNSF will become the second major freight railroad to allow some of its employees to report safety concerns anonymously through a federal system without fear of discipline.

The Federal Railroad Administration announced Thursday that the railroad owned by Warren Buffett’s Berkshire Hathaway had agreed to let its roughly 650 dispatchers participate in the program that all the major railroads promised to join after last year’s disastrous Norfolk Southern derailment in Ohio.

“Rail workers deserve to know they’re safe when they’re on the job — and if they experience anything that compromises their safety, they should be able to report it without worrying if their job is in jeopardy,” said Transportation Secretary Pete Buttigieg.

Buttigieg has been urging the railroads to improve safety ever since the February 2023 derailment.
