While running a Green Line test train in areas where defects had previously been detected, crews identified speed signs that need to be moved to implement block restrictions. As a result, the global speed limit will remain in place until this manual process is completed.
In an update to the update, the MBTA says:
The MBTA has identified 30 speed limit signs to be relocated on the Green Line, and that work is underway today. After this work is completed, the MBTA will resume test trains on the entire stretch. The MBTA apologizes for the continued disruption of service to its riders.
Yesterday, interim MBTA General Manager Jeff Gonneville had said that while the T would lift the “global” speed limits — as low as 10 m.ph. in some places – it would maintain new speed limits in certain track “blockages” until inspectors could walk those stretches and track workers could fix any problems they identified, so even without the “global” restrictions trips would still take more time.
