Talks aimed at settling a strike between train engineers and New Jersey’s huge commuter railroad will pick up on Saturday and continue Sunday.

As the strike entered its second day, the agency’s chief executive, Kris Kolluri, said that he planned to meet with union representatives at 1 p.m., a day earlier than planned.

Commuters in the New York City suburbs must depend on alternate modes of transportation as engineers seeking higher pay walk out of work.
