NEWARK — NJ Transit has some advice for its riders who will bear the brunt of service disruptions caused by major repairs at New York's Penn Station this summer:

Leave early. Very early.

Executives from the transit agency faced questions Wednesday in Newark from lawmakers upset they weren't consulted on the plan announced last week.

Trains from Morris and Essex counties in northern New Jersey will be rerouted to Hoboken during peak periods.

However, NJ Transit Executive Director Steve Santoro said those lines will run normal service into New York until 7 a.m. weekdays.

Lawmakers questioned why NJ Transit's other rail lines won't be affected.

Amtrak is going to shut three of 21 tracks for two months this summer to repair and replace aging infrastructure at Penn Station after recent derailments.
