State transportation officials say the breakdowns and delays that plagued the MBTA commuter rail system over the winter were “unacceptable” and maintenance procedures are being reviewed to prevent similar problems in the future.
Officials were called before the Legislature’s Transportation Committee on Tuesday to explain the failures that left many commuters angry and frustrated during one of Boston’s harshest winters in years.
MBTA general manager Richard Davey said while 78 percent of commuter trains ran on time during the months of December, January and March, that wasn’t good enough.
Secretary of Transportation Jeffrey Mullan says the MBTA is replacing or overhauling aging locomotives and retraining maintenance workers to spot early signs of equipment problems.
He also promised to improve communications so that riders are notified quickly about delays.
