Amtrak Trains 151 and 181 will not operate on Thursday, but riders can take MARC, Maryland Transit Administration officials said.
Amtrak Northeast Corridor service between New York and Philadelphia remains suspended after a deadly derailment Tuesday night just north of Philadelphia.
MTA officials said passengers should plan on riding MARC Trains 517 or 523. MARC weekly and monthly passes from Perryville, Aberdeen and Edgewood south to Baltimore and Washington will be honored.
All regular MARC Penn Line service is running on a regular schedule Thursday.
