The MBTA announced during its August Board meeting that Orange Line trains will be able to reach 55 mph on select portions of the line starting August 24, 2025. The new increased speeds impact stations between Oak Grove and Assembly Station.
The previous maximum speed on the Orange Line was 40 MPH. The segment between Assembly and Oak Grove was originally designed for 55 MPH, but as track infrastructure declined, speeds were lowered for safety reasons.
This is the first time documented that the Orange Line reached 55 mph.
As part of the Track Improvement Program (2023 – 2024), the MBTA removed more than 220 speed restrictions and replaced 250,000 feet of rail across the system, saving riders 2.4 million minutes every weekday and generating nearly $1 million in economic benefit every day. Regular maintenance has been ongoing to continuously improve the safety, reliability, and efficiency of the MBTA’s rail network.
