NJ Transit has been under the microscope lately due to the amount of trains canceled without warning due to unexcused engineer absences and PTC installation.

Gov. Phil Murphy blamed the Christie administration for neglecting to fund the agency, thus causing a shortage in staff.

But some Republican lawmakers say that they have an issue with Murphy’s words. Senate Republican Leader Tom Kean Jr. says that it is time for state lawmakers to work together to address the engineer shortage.

"We've got to look forward. The commuters can't wait one more day to find a solution,” Kean says. “What people are seeing…is you've got a personnel problem at New Jersey Transit that's rippled into a statewide transportation breakdown. And we've got to focus on the short-term policies that will fix this problem, as well as the long-term."

Murphy has admitted that he underestimated the extent of NJ Transit's problems. He says that he promises to put commuters first.
