Has the third track south of Wilmington been completed, if it has, has anyone heard from SEPTA & DTC on when Regional Rail will be expanded to Newark, DE or will it wait until the new train station proposed there is completed.
Just for clarification, are you asking if/when SEPTA will increase service to Newark? Because SEPTA already serves Newark DE via Wilmington, albeit only during peak hours.
Any increased service would have to be funded by DART, so it's not really up to SEPTA.
