Passengers who ride Maryland Area Regional Commuter trains will get a chance to meet management Tuesday at Union Station.

State officials said personnel from MARC, Amtrak and CSX will all be on hand to answer questions from passengers across all lines.

The event is being held in the vicinity of Gates B and C from 3:30 to 6:30 p.m. Tuesday.

The Brunswick Line carries passengers between Washington and points north and west, including Frederick and Martinsburg, W.Va. The Camden Line connects Washington and Baltimore, and the Penn Line runs from Washington through northeastern Maryland via Baltimore.

The state pays CSX $44.7 million annually to operate the Brunswick and Camden lines on CSX-owned tracks. The state pays Amtrak $47 million to operate the Penn Line.

CSX’s contract to operate the Brunswick and Camden lines ends in June 2012, and CSX is not bidding to renew it, according to MARC officials. MARC is the only commuter rail system that CSX Transportation operates and the company has said it wants to focus on its freight business. Amtrak provides commuter services in six states and access in several others.
