You know that Springfield factory where a company that never before assembled a rail car in the United States is under state contract to build a fleet of new Orange and Red line trains? It's a hot mess — one that outgoing Governor Charlie Baker has left to incoming Governor Maura Healey to fix. A Dec. 22 letter from MBTA Deputy Director Mark DeVitto to the project manager of CRRC MA — the Chinese company that's producing the rail cars — presents a worrisome list of workmanship and inspection reporting lapses. "Given the breadth, number and age of chronic quality issues that have remained unresolved, it becomes abundantly clear that CRRC MA's management has completely abandoned its core responsibilities and commitment to lead, monitor and support quality management," wrote DeVitto. "This situation has already caused major disruptions, rework and delays in production and delivery of Orange and Red Line cars."
