More Baltimore-area residents are opting to use MARC trains as ridership increased for the fifth consecutive month since January.

Average daily ridership has exceeded 30,000 with May having 32,604 daily commuters, a 6 percent increase over May 2007, according to a news release.

The Penn Line, which is operated by Amtrak and runs between Perryville and Washington, D.C., via Baltimore and Baltimore/Washington International Thurgood Marshall Airport, was the most traveled MARC, with an average of 20,414 daily boardings in May.

The Camden Line, which is operated by CSX and runs from Baltimore to Washington, had an average of 4,466 daily boardings.

"We are pleased that our MARC train riders view the service as a viable alternative to driving, especially as we continue to experience rising costs associated with driving," Paul Wiedefeld, Maryland transit administrator, said in a statement.
