The clock is ticking ahead of a potential NJ Transit rail strike. The trains could stop running at 12:01 a.m. Friday if locomotive engineers don't get the salary increase they want.New Jersey Gov. Phil Murphy says all options are on the table if engineers walk off the job,

A strike of train engineers could happen May 16. And NJ Transit's 172,000 weekday rail riders need to consider alternatives.

NJ Transit said that 350,000 commuters would be affected by a strike. If the strike occurs, a contingency plan would move rail commuters to its buses. However, only about 20%, or 20,000, of its daily rail commuters could be accommodated by the plan, according to Kolluri.
