Metrorail’s New Heavy Repair and Overhaul Facility

Metrorail's New Heavy Repair and Overhaul Facility_Rendering


While Metro has 10 railcar service and distribution facilities that help keep the agency’s nearly 1,300 railcars safe and reliable, there is no location dedicated exclusively to heavy repair and overhaul functions. Currently, Metro’s heavy repair and overhaul work takes place alongside regular service and repair work at two separate facilities. 

The new Metrorail Heavy Repair and Overhaul (HR&O) Facility will be outfitted with bays for 20 rail cars, a rail car truck shop and storage tracks. The facility will provide Metro with one site where all major overhaul work can take place, improving work efficiencies and modernizing Metro’s major railcar overhaul processes. The facility will be located at 3636 Pennsy Drive in Landover, Maryland, with a connection to the Orange Line. Site construction is expected to begin in 2023 and to open in early 2025.

Improved Efficiency and Reliability 

The state-of-the-art HR&O Facility will allow Metro to implement a new and improved Scheduled Maintenance System (SMS), which focuses on delivering scheduled maintenance for each railcar and its subsystems. SMS will eliminate major predicted failures, increase car availability and decrease delays caused by railcar maintenance.  

Additionally, the larger facility size will allow Metro employees to perform critical heavy repair and overhaul functions onsite, eliminating the need for contractors and offsite repairs. This will significantly improve maintenance and repair turnaround times. 

Metro’s sustainability commitment will continue with this project, with a goal of achieving LEED certification through the integration of green features that conserve energy, improve stormwater management and optimize indoor environmental quality.

Taking A More Modern Approach to Repairs and Maintenance  

When it opens, the HR&O Facility will feature multiple innovative work areas designed to provide the space and technology required to efficiently complete heavy repairs, such as:

  • A workshop on the mezzanine level where roof-mounted HVAC equipment can be lifted straight from railcars onto the mezzanine for maintenance and repair
  • A truck shop where tracks are removed from railcars and then disassembled so that parts (e.g. truck frame, wheels, axels and gearboxes) can be repaired or replaced
  • The north side of the building will have 20 maintenance bays, where railcar bodies will be brought in by crane for disassembly, repair and rebuild. This work could involve the removal of all equipment cases, doors, control equipment, seats, windows, floors, etc.

Before being returned to the operating fleet, in like new condition, every serviced railcar will be sent through testing and quality control to be assessed for final certification.

Did you know?

Metro’s 7000-series railcars are currently the newest in the fleet and make up more than half of all railcars in the Metrorail system. These are the seventh generation of railcars since Metrorail began running in 1976 and will be the first series maintained using the SMS approach.
