The Massachusetts Bay Transportation Authority (MBTA) has completed critical track work on the Orange Line while service was suspended between Wellington and Back Bay stations from May 28 through June 6. As a result of unencumbered access to track areas, crews lifted ten safety-related speed restrictions by accomplishing the following work:

  • Replaced over 12,000 feet of running rail, 388 ties, 84 cologne eggs (fasteners that allow crews to directly affix rail to concrete pads), and 250 plates;
  • Resurfaced and tamped over 7,800 feet of track;
  • Performed over 1,100 feet of full depth track construction, overhead station inspections of platforms, entrances, and lobbies; tunnel inspections; accessibility improvements; and signal improvement work;
  • Installed 500 feet of rail at Sullivan Square; new cable, power wires, and fiber optic; and signal equipment from 60 track circuits;
  • Hand-tamped 100 feet of track to alleviate a speed restriction;
  • Accomplished security improvements at Chinatown;
  • Inspected electrical rooms to upgrade the station’s lighting; and
  • Repaired elevated walkway with new concrete for a smooth walkway surface;

The MBTA also collaborated with its partners at MassDOT during this Orange Line service suspension to support necessary work as part of Maffa Way/Mystic Avenue Bridge Superstructure Replacements project, which will replace the two deteriorated bridge superstructures and improve bicycle, pedestrian, and transit facilities.
