A possible strike against New Jersey Transit by the engineers' union could lead to a shutdown of NJ Transit train lines, causing a disruption to over 350,000 commuters.

NJ Transit is spending $2.7 billion to retire all its old trains, which will increase reliability for riders by 2031.

Gov. Phil Murphy campaigned for the State House eight years ago on a promise to fix New Jersey’s transit system. He called NJ Transit a “national disgrace,” and blamed his predecessor Chris Christie for not investing in the system used by more than 170,000 weekday rail riders.
