An ongoing Boston Green Line track repair program has reduced derailments, but an aggressive maintenance program, improved safety standards and more investment are critical for avoiding more derailments and other system failures, according to a state transportation oversight report.
The Massachusetts Bay Transportation Authority Green Line track maintainers are “no longer in a maintenance mode but in ‘repair the issue just enough’ to return to a restricted service mode … not sustainable in the long run,” stated an oversight report last fall.
