Connecting downtown Baltimore to the suburbs northwest of the city and terminating in Owings Mills, Md., the Maryland Transit Administration (MTA) Metro SubwayLink runs approximately 15 miles and sees an annual ridership of nearly 13 million.

During a four-week timeframe, RailWorks Track Services rehabilitated numerous portions of the line, accomplishing a wide range of work in short windows. The crews completed repairs on direct fixation tunnels, ballasted track, open deck bridges and direct fixation bridges.

The project scope included concrete and timber tie replacement, ballast resurfacing and replacement, fastener rehabilitation, plinth and concrete repair, running rail replacement, track destressing and track and rail resistance testing. The project was completed on time and within budget.

Unique Features

Due to the short work windows, the RailWorks team had to coordinate with MTA crews to change work blocks throughout the outage. Additionally, the team had limited locations for material and crew access during the project duration.

Railway Track & Structures named the MTA Metro SubwayLink Priority Repairs the 2019 Project of the Year in the Passenger Rail Maintenance category.
