The Metra Board of Directors approved a $70.9 million contract to purchase 15 remanufactured locomotives to begin to replace Metra’s aging fleet. The contract with Progress Rail Locomotives of La Grange includes options to buy up to 27 additional locomotives, if funding is available.
Progress Rail will take existing EMD SD70MAC freight locomotives and upgrade and configure them for passenger use. All components will either be refurbished, upgraded or new. The newly remanufactured locomotives will be designated as SD70MACH locomotives.

The introduction this year of 24 used but new-to-Metra locomotives that were purchased from Amtrak will reduce that percentage to about 45%, and the addition of the remanufactured freight locomotives will reduce that percentage to 14% by 2023.
Newer locomotives not only will increase reliability, but they will reduce operating costs, since the older locomotives are increasingly expensive to maintain and operate.
Metra’s RFP allowed companies to provide proposals for either new or remanufactured locomotives. Metra chose remanufactured locomotives primarily because it can buy more of them than new locomotives. A greater number of newer locomotives means Metra can replace a greater number of older locomotives and operate a greater number of trains with more reliable locomotives.
One big improvement will be in the traction motors, which deliver the power generated by the diesel engine to the wheels. The remanufactured locomotives will have AC traction motors, which are far more durable and reliable than the DC traction motors in Metra’s older locomotives. For example, Metra currently needs to replace about 160 DC traction motors annually. On Metra Electric cars, the oldest of which have had AC traction motors for 12 years, Metra has not had to change a single traction motor.
The remanufactured locomotives have a similar design to Metra’s F59 locomotives so Metra will be able to use the same parts inventory and won’t need different training and maintenance programs. There will be a 34% increase in horsepower.
Another major upgrade is a microprocessor-controlled brake system.
The remanufactured locomotives will meet the Environmental Protection Agency’s Tier 3 emissions standards. Replacing 42 of Metra’s current locomotives that are rated Tier 0+ with 42 Tier 3 locomotives will eliminate 61 tons of nitrous oxide emissions annually — the equivalent to taking 6,600 cars off the road.
The announcement highlights the long-standing partnership between the Class I railroad and the commuter rail system, dating back to Metra's creation in 1983.
Crews completed a significant portion of the testing required before commissioning the new, digital signaling system, which will bring important upgrades that strengthen Red Line service reliability for riders and provide Red Line Operations the ability to route trains more quickly, turn trains around faster, and recover from unplanned disruptions more efficiently, said MBTA officials.
In addition to new projects, progress continues on a multiyear effort to upgrade track, electrical, and signal systems on the Metra Electric Line to accommodate the expansion of service on the South Shore Line.
The Maryland Transit Administration is advancing the nearly $1.4 billion Light Rail Modernization Program, which modernizes the Baltimore Central Light Rail Line from Hunt Valley to BWI Thurgood Marshall Airport with new, low-floor vehicles and upgrades to all light rail stations, systems, and maintenance facilities.
The Peninsula Corridor Joint Powers Board recently met for a budget workshop, during which staff outlined the significant service reductions Caltrain could be forced to make without new external funding.
Funding for the purchase of the railcars comes from the nearly $220 million in additional capital dollars Gov. Josh Shapiro allocated in November 2025 to support urgent safety upgrades and infrastructure improvements.
With major events and increased travel expected across the state this summer, the Administration is focused on making sure people have a reliable, affordable alternative to driving so we can reduce congestion, support daily commuters, and keep Massachusetts moving.
