The MTA has an operating agreement with NJ Transit to provide service on the Pascack Valley and Port Jervis lines, which the MTA pays for. These lines are crucial to West of Hudson commuters, and unfortunately this service is being reduced. MNR express trains 1618 and 1639, as well as the regular operation of Friday-only outbound train 9653, will be temporarily canceled from June 4 to the end of the 2018. These service cuts are especially worrying for Rockland County riders, as a 2012 study found that Rockland pays $42 million more to the MTA than it gets back in service.
