After a successful two-month pilot program, the agency is expanding the number of so-called "quiet cars" to all trains that go into Newark and New York Penn stations during peak hours.
Passengers on the first and last cars of those trains are asked to refrain from using cell phones and to disable the sound on computers and other electronic devices.
NJ Transit Executive Director James Weinstein says rider feedback on the program has been "overwhelmingly positive."
The quiet car concept originated with Amtrak in 1999 and has spread to commuter rail operations on both coasts.
