Maryland officials are scheduled to break ground Monday on a new Maryland Area Regional Commuter train station at Halethorpe.

The $21 million project will include new platforms to improve boarding, a pedestrian bridge and a kiss-and-ride dropoff site.

Gov. Martin O’Malley and Transportation Secretary Beverley Swaim-Staley are scheduled to appear Monday afternoon at a groundbreaking for the project, designed to improve access for 1,200 MARC passengers who use the station each weekday.

Maryland Transit Administration spokesman Terry Owens said construction is expected to take about two years.

The station serves riders on MARC’s Penn Line, which runs from Washington through northeastern Maryland via Baltimore. Last month MARC overhauled the schedule for the Penn Line to reduce crowded conditions on some trains, relieve stress on locomotives, and serve growth in employment due to BRAC relocations to Fort Meade and Aberdeen.
