T derailment blamed on ‘series of contributing factors’

It’s beginning to look like the MBTA may never pinpoint the cause of a March 16 derailment of one of its new Orange Line trains. 

At a meeting of the Fiscal and Management Control Board on Monday, Deputy General Manager Jeffrey Gonneville indicated the T and the Chinese manufacturer of the trains disagree on the principal cause and that a “series of contributing factors” may ultimately be blamed for the derailment. 

The stakes are high in this derailment investigation because all of the T’s 252 Red and 152 Orange line vehicles are being replaced by CRRC Mass., the Chinese manufacturer. The relatively few new vehicles delivered to the T so far have been on hold ever since the derailment and it’s still unclear when they will return. 

The new Orange Line train was moving from one track to another at slow speed in a work zone near the Wellington train yard in Medford when it derailed. Initial concerns focused on aging infrastructure – a commonplace issue at the T – since the train made the move between tracks using a 46-year-old switch. 

The switch was replaced along with track in the area, but Gonneville on March 29 said it was unclear if the switch was the cause of the derailment. He declined to say whether 46 years exceeded the switch’s useful life, noting it would depend on how heavily it was used over the years. “Newer is better,” he conceded at the time. 

On May 10, Gonneville said he suspected the problem had to do with the vehicles themselves – specifically pads attached to the trucks which enable the vehicles to turn. He said testing indicated the pads were wearing down faster than expected. When that happens, he said, the pads tend to grip harder, increasing “rotational force” that makes it more difficult for the vehicle to turn. 

On Monday, Gonneville outlined a handful of other infrastructure issues that could have played a role. He said the switch, in addition to being old, lacked a guardrail that helps to keep a train on the track in tight turns. He also outlined two other issues with the track itself that could have been contributing factors. 

There was no “single point of failure” that caused the derailment, Gonneville said. 

“The MBTA right now does feel pretty strongly that the guardrail itself on the switch and the excessive rotational force were more than likely the key contributing forces that led to this incident,” he said. “But in full fairness, CRRC is of the opinion that really the infrastructure items that I’ve outlined here played a greater or more key role in influencing the derailment itself.”

Gonneville said the T and CRRC both agree that the rotational forces caused by pad wear exceeded design limits. He also said the T is shutting down a stretch of the Orange Line from June 26 through July 1 to replace several more switches – including one that is heavily used near the Wellington yard — that are in similar shape to the one where the derailment occurred. He said the new switches will all have guardrails.



Janey fires White: After months of drama, acting Mayor Kim Janey followed through on her pledge to fire Boston Police Commissioner Dennis White. Here’s what you need to know.

— The acting mayor said White admitted “he hit and pushed members of his household.” She criticized him for vilifying his former wife, for playing the race card (White is Black), and for failing to fully cooperate with an investigation into past allegations of abuse.

— Janey said a national search will be launched for a new commissioner but no hiring decision will be made until the next mayor is elected in November. Interim commissioner Gregory Long will remain in place until then.

— Political fallout for Janey was minimal, as her mayoral rivals supported the decision. The cost to the city is unclear, as White indicated through his attorney that he would pursue civil rights claims against the city “to recover for his own losses” and to ensure the way White was treated doesn’t happen to anyone else.

Red to Blue: The MBTA estimated it would cost $850 million to build a subway connection between the Red and Blue lines and, assuming money can be found for the project, work could begin in 2025 and be completed by 2030. 

— The project offers a lot of convenience, allowing Red Line riders from Cambridge and Somerville easier access to Logan International Airport and Blue Line riders one-seat rides to Massachusetts General Hospital. 

— A new Blue Line station would be needed underground at Charles/MGH, with exits to the existing Red Line station there and to a proposed Mass General medical building along Cambridge Street.

— Construction could be messy. The plan calls for digging up Cambridge Street, putting in the subway tunnel, and then covering it up again. The $250 million cut-and-cover operation works out to $114,000 per foot. Read more.

T notes: The Fiscal and Management Control Board reaches a compromise on fares based on a rider’s income level, calling for the development of a pilot project to test the concept. The actual decision whether to proceed would be left to whatever board emerges to oversee the T after the current one expires at the end of this month. The board also passed a budget for the coming fiscal year and said a settlement for COVID-19 delays with the contractor working on the Green Line expansion is in the offing. Read more.

Not in the constitution: James Rooney, the president and CEO of the Greater Boston Chamber of Commerce, says a new tax rate for people earning more than $1 million doesn’t belong in the state constitution.

Boston School Committee member Lorna Rivera resigned following the emergence of racially charged texts she sent to fellow committee member Alexandra Oliver-Dávila — including a comment that she is “sick of Westie whites,” a reference to West Roxbury white residents — during a meeting last fall to consider changes to the city’s exam school admission criteria. (Boston Globe) Oliver-Dávila, now the committee chair, also made disparaging comments about West Roxbury. The committee members apparently released the texts to Globe columnist Marcela García when they learned the texts were about to be leaked. “Rivera and Oliver-Dávila’s texts, while inappropriate and hurtful, reflected their own lived experience and prejudice,” Garcia wrote. “Rivera’s departure from the school board, where her goal had been to elevate the needs of marginalized groups at BPS, represents a big loss. That’s why Oliver-Dávila should stay.”
