The railroad industry has sued to block a new minimum crew-size requirement that Ohio imposed after a fiery train derailment in East Palestine in February. Republican Ohio Gov. Mike DeWine signed the new rule in March as part of the state's nearly $13.5 billion state transportation budget. It mandated a two-person crew for freight trains.

A bipartisan group of U.S. senators has proposed legislation that would make railroads, like the one involved in last month’s fiery crash and toxic chemical release in Ohio, subject to a series of new federal safety regulations and financial consequences.
