Railroads and unions are working to avert a strike that could halt freight trains across the US and, if it lasts, create snarls at ports.

Railroads and unions are facing a Friday deadline on talks that impact some 125,000 workers as the administration of US President Joe Biden considers steps to prevent a strike from bringing more supply chain and inflation pressures.
