NJ Transit and an engineers’ union appear to be steaming ahead to the first major rail strike in decades starting early Friday, even as both sides convene in Washington, D.C., where they pledged to continue negotiations.

Beyonce fans might be better off riding a horse to next week’s “Cowboy Carter” concerts at MetLife Stadium if a strike shuts down NJ Transit rail service. NJ Transit’s train engineers could walk off the job as soon as Friday after Brotherhood of Locomotive Engineers members voted to reject a tentative agreement between the leaders of the agency and the union.

Fans can also get to the concerts by taking taxis or ride share services like Uber and Lyft. NJ Transit is warning concertgoers of expected surge pricing on ride share apps and anticipating delays of up to two hours for rides requested after the concert.

A NJ Transit employee is facing criminal charges for allegedly stealing hundreds of phones and reselling them, netting more than $700,000.
