MARC to add weekend train service between Baltimore and D.C.

Sometime in the future, people in Baltimore will be able to take a train down to Washington, D.C., for just $7.
That’s right: the MARC train plans to add weekend service.
The Baltimore Business Journal has the story:

Maryland’s Department of Transportation has allotted $100 million for improvements to the state’s MARC train service. Part of the upgrades include creating weekend service for the MARC Penn Line, which runs from Baltimore’s Penn Station to Union Station in D.C.

The money comes from the $4.4 billion Transportation Infrastructure Investment Act signed by Governor Martin O’Malley on Thursday. (You know: the “gas tax” bill.)
Suppose the MARC can add a real-time train-tracking mobile app to its repertoire too?
