Boston’s Red Line riders are facing some of the worst delays in years as the oldest trains in the MBTA system keep breaking down in the cold. This week, there were just 9 trains running during rush hour—less than half the usual number—thanks to repeated breakdowns at Ashmont, JFK/UMass, and Davis Square. New trains were supposed to replace these 1960s-era cars by now, but only 6 have arrived, with deliveries stalled. How much longer can the city’s busiest subway line limp along like this? What’s your experience been this week? #Transportation #MBTA #RedLine
