Gov. Phil Murphy delivered the news to those attending the NJ TransAct conference in Atlantic City.
"Regular rail service will resume on both the Atlantic City and the Princeton Branch Dinky lines on May 12, nearly two weeks ahead of schedule," he said.
For the Atlantic City line, Murphy says riders are in for a pleasant surprise.
"Riders here in Atlantic City will find an improved schedule that was built in response to their needs and to the feedback of employers and elected officials, and which will significantly reduce wait times between trains," he added.
The governor says NJ Transit will add a second morning rush-hour train to Philadelphia.
He says that move will close the gap in service that often left commuters who were a minute or two late for their train sitting trackside for up to two hours waiting for the next train to show up.
And, Murphy says, NJ transit isn't just looking out for South Jersey riders.
"It's also about connecting Philadelphia and the eastern part of Pennsylvania residents with the attractions here in Atlantic City and up and down the entire shore," he said.
