The Maryland Department of Transportation/Maryland Transit Administration is set to begin a $35 million project designed to expand and modernize the Maryland Area Regional Commuter (MARC) train storage facilities at the Martin Maintenance Yard in Baltimore County.
Expanding storage capacity at the rail yard is a key component to delivering more frequent service that better serve existing, changing and new travel markets as outlined in the MARC Growth and Transformation Plan, state officials said in a press release.
The project scope includes increased storage capacity for MARC trains at the Martin Maintenance Yard located near Martin State Airport, new tracks with catenary electrification, crossover tracks, a new inspection pit and water hydrants, air piping extensions and light fixtures to support train car maintenance.
The yard and shop improvements are needed to support the Maryland Transit Administration’s future commitment to operate electrified trainsets on the Penn Line following the completion of Amtrak’s Frederick Douglass Tunnel, state officials said.
“Investing in our rail infrastructure today ensures we can deliver improved service in the future,” said Maryland Transit Administrator Holly Arnold. “It is a critical element in our goal to transform MARC Train from a commuter rail to a regional rail service.”
The Martin Maintenance Yard project also supports Amtrak’s redevelopment of Penn Station in Baltimore, plans that require an alternative to Penn Station as a storage area where many MARC trains are currently located when not in service.
The $35 million project is set to begin later this fall, with completion slated for summer 2027. It is being funded by a discretionary grant from the Federal Railroad Administration’s Consolidated Rail Infrastructure and Safety Improvements Program, according to state officials.
