New Jersey Transit’s train engineers have reached a tentative deal to end their three-day strike that had halted service for some 100,000 daily riders, including routes to Newark airport and across the Hudson River to New York City.

The NJ Transit strike is over after the Brotherhood of Locomotive Engineers and Trainmen (BLET) approved a deal Sunday, but train service did not immediately resume Monday. The engineers strike has halted trains across New Jersey for four days.

Negotiators for New Jersey Transit and the union representing 450 striking engineers have reached a tentative labor agreement that could bring an end to the strike that began Friday, according to TK
