MINEOLA, N.Y. (AP) — The chief negotiator for the unions at the nation’s largest commuter railroad emerged from the restart of talks Wednesday citing progress and vowing to continue working toward a deal that avoids a strike set for 12:01 a.m. Sunday.

“We’re not leaving until we can get this done,” Anthony Simon said outside the Manhattan law office where representatives from the unions and the Long Island Rail Road talked for about five hours Wednesday.
