OMAHA, Neb. — The contract imposed on railroad workers last fall didn’t resolve their quality-of-life issues, but already this year there are indications the major freight railroads are starting to address some of their concerns.

Union Pacific says it will stop imposing temporary limits on certain businesses’ shipments while it reviews the policy that federal regulators and shippers criticized at a hearing in mid-December.

OMAHA, Neb. — The U.S.’s third-largest railroad union rejected a deal with employers Oct. 10, renewing the possibility of a strike that could cripple the economy. Both sides will return to the bargaining table before that happens.
