Massachusetts Bay Transportation Authority Red Line Service Life Extension Massachusetts HNTB is assisting MBTA’s team with the performance of a fleet condition assessment of Red Line vehicles and the development of a scope of work for an in-house targeted investment service life extension program. The investment program will aim to balance the need for safety and reliability with the understanding that the vehicles only have a few years of operation remaining.

The assessment will target critical components for safety and reliability.

HNTB is inspecting the vehicles and documenting its findings. Particular attention is being paid to critical systems such as car body, trucks, air and brake systems, power systems, doors, controls, communications and other aspects that could have in-service failures, which negatively impact passengers.

Washington Metropolitan Area Transit Authority Bus Midlife Overhaul Assessment Washington, D.C. To support the Washington Metropolitan Area Transit Authority’s (WMATA) goal of improving fleet reliability, HNTB conducted a comprehensive evaluation of its bus overhaul program — focusing on optimizing the selection, scheduling and execution of midlife overhauls to align with industry best practices.

HNTB provided a detailed review of vehicle selection criteria, overhaul methods and workflow processes.

HNTB also benchmarked WMATA’s practices

against peer agencies, assessed for mini-overhaul opportunities and evaluated facility operations and equipment maintenance.

HNTB delivered actionable recommendations that optimize overhaul efficiency, streamline parts procurement, and strengthen quality assurance — enhancing WMATA’s fleet reliability and service performance.
