Maryland's MARC commuter train service will be shuttling riders into the District on two of its three lines for Obama's second inauguration.
The Maryland Transit Administration plans to run limited service during the morning and afternoon of Jan. 21 on the Penn and Brunswick lines. The Camden Line will not operate.
Previously, the agency had planned to offer some service on its Penn Line. Normally the train service does not operate on that day, which is the Martin Luther King federal holiday.
Riders will pay normal ticket prices but can buy special commemorative tickets the state agency will create next month.
"It is a great opportunity to showcase the important role mass transit plays in transporting the public throughout Maryland," MTA Administrator and CEO Ralign T. Wells said.
MARC's Virginia counterpart, Virginia Railway Express, said earlier this month that it will not be offering service on Inauguration Day. Metro, meanwhile, will be offering extra peak service for much of the day - and charging peak fares and parking fees for it - despite the holiday. Metro has forecasted significantly fewer viewers at the Inauguration compared with the record-breaking 2009 event.
