In coordination with state partners at the Pennsylvania Department of Transportation, beginning June 1, Amtrak is fully restoring Pennsylvanian service (New York – Philadelphia – Pittsburgh) frequencies and Keystone Service (New York – Philadelphia – Harrisburg) trains will begin operating again on a modified schedule in response to anticipated increased demand. Modified Keystone Service will include nine weekday roundtrips and six roundtrips on weekends. Keystone Service will temporarily operate between Philadelphia and Harrisburg only, with no service between New York and Philadelphia. Pennsylvanian service will include one daily roundtrip operating normally between New York, Philadelphia and Pittsburgh. All trains will be reserved to allow for physical distancing. Amtrak is also restoring Acela service on the Northeast Corridor on a modified schedule beginning June 1. Modified service will include the restoration of three weekday Acela roundtrips. Northeast Regional frequencies will also be increased from eight to 10 roundtrips.
