NORTH BRUNSWICK — Gov. Chris Christie says he will take "every action that is necessary" to make sure New Jersey Transit train engineers show up for work after dozens of trains were canceled earlier this week because of a manpower shortage.

Christie addressed the trains canceled earlier this week at an unrelated event Thursday in North Brunswick.

He says that he thinks the reason for the delays were "people not showing up to work" and that it was likely a coordinated effort.

The Republican says legal action was threatened, but didn't disclose more details.

Train engineers' union leader James Brown said Wednesday that NJ Transit should hire more workers.

This week's cancellations came during the second week of extensive repairs at New York Penn Station that already have affected service for hundreds of thousands.
