Should your local transit agency prioritize full electrification over purchasing new diesel-electric vehicles?

The MBTA Board of Directors recently authorized a $310.4 million contract with Siemens to purchase 20 new locomotives, split between diesel-electric and battery-electric models. Additionally, the board approved an $84 million procurement of 65 new electric hybrid buses.

Why it matters

These purchases aim to modernize the aging MBTA fleet and reduce emissions, specifically targeting rail sections that lack electrification. The battery-electric locomotives are slated for the Providence Line, while the diesel models are expected to cut emissions by 80%.

The $310.4 million locomotive contract covers 10 diesel-electric and 10 battery-electric engines, while the $84 million bus deal is supported by $79 million in federal funding.

The players

MBTA Board of Directors

This body governs the Massachusetts Bay Transportation Authority and is responsible for making major capital expenditure decisions for the state rail and bus systems.

Siemens

This is a global industrial manufacturing company that produces transportation equipment and was selected to provide the new locomotive fleet.

Phil Eng

As the General Manager of the MBTA, he is tasked with executing the operational directives and procurement contracts authorized by the board.

Federal Transit Administration

This federal agency provides financial assistance to support public transportation systems across the United States.

The details

General Manager Phil Eng will oversee the acquisition of the trains and buses to improve system reliability. The transition to battery-electric locomotives will specifically service non-electrified routes, marking a shift in how the transit authority manages power across its rail system.

October 22, 2026: MBTA Board of Directors approved locomotive and bus purchases.
Spring and summer 2028: Expected delivery of 65 new hybrid buses.
Mid-2029 to mid-2030: Expected delivery of new diesel-electric locomotives.
2030 to 2031: Expected delivery of new battery-electric locomotives.

Roadmap

This acquisition aligns with the broader transit industry trend of moving away from older, emission-heavy combustion engines toward hybrid and battery-powered alternatives. It positions the MBTA to catch up with national rail modernization standards by investing in technology that replaces legacy rolling stock.

Commuters on the Providence Line can eventually expect updated, quieter, and cleaner train service once the battery-electric locomotives are deployed. The introduction of hybrid buses may improve overall transit service reliability and reduce daily maintenance-related delays across the network.

The takeaway

Transit agencies are increasingly prioritizing electric hybrid technology to meet environmental goals while managing the challenges of non-electrified rail routes. Residents should anticipate a multi-year transition as these new vehicles are phased in to replace older, less efficient models.
