NJ Transit trains could stop running at 12:01 a.m. Friday if locomotive engineers go on strike over the salary increase they want​.

In 2016, an agreement was announced in the final hours before a March 11 strike deadline was set by all of NJ Transit’s 15 rail unions.

If the engineers do walk off the job, the agency plans to increase bus service, saying it would add “very limited” capacity to existing New York commuter bus routes in close proximity to rail stations and will contract with private carriers to operate bus service from key regional park-and-ride locations during weekday peak periods.
