Amtrak announced it is suspending all Keystone Service beginning Wednesday, and all Pennsylvanian trains on Thursday as part of the adjustment of services due to COVID-19.
The Keystone Service line travels from Harrisburg to New York City by way of Philadelphia.
The Pennsylvania trains travel from New York City to Pittsburgh.
"While Amtrak continues to operate across the nation, we have adjusted some services due to significantly reduced demand in key markets," Amtrak said on its website.
Amtrak is also adjusting service on its Northeast Corridor, Hartford, Valley Flyer, New York State, Cascades, Amtrak Downeaster, and Winter Park Express service lines.
Other services may also be impacted as circumstances change, Amtrak said. Café service will be suspended on some trains operating between Washington DC and New York City.
Customers with reservations on trains that are being modified will be contacted and typically be accommodated on trains with similar departure times or another day, according to Amtrak.
Amtrak is waiving change fees on all existing or new reservations made before April 30, 2020.
