The order is expected to be at least 15 months late, and I don't see that improving as the pandemic surges once again. I'm not sure that CRRC's Massachusetts plant can be considered to be "back to normal" at this point.
The Massachusetts Bay Transportation Authority has taken its new Orange Line and Red Line subway cars out of service as it investigates Tuesday’s low-speed derailment of a train with 100 passengers aboard. The Boston Herald also reports a bus bridge around the accident site at Wellingon station in Medford, Mass., between the Oak Grove and Sullivan stations, will remain in place for three weeks as MBTA crews repair a switch damaged in the derailment and perform other infrastructure work. MBTA Deputy Press Secretary Lisa Battison said the cars built in Springfield, Mass., by a subsidiary of Chinese equipment manufacturer CRRC are being removed from service “out of an abundance of caution … to allow vehicle engineers to perform a thorough analysis of the cars’ performance.” A total of four trainsets are being sidelined.If not, then...

On a "real" train, going around a curve, the kingpin can't hold the car perfectly upright and the outside of the truck frame (specifically the outer end of the truck bolster) leans on the underside of the car body (specifically on a fixed bolster under the car).You forgot to mention the PCC in your avatar uses the kingpin method.

And since the derailment occurred along a section of track that was undergoing repairs, it seemed likely at the time that the culprit would be aging rails or a faulty switch, not brand-new train cars. Still, as a precaution, the Massachusetts Bay Transportation Authority pulled all the new subway cars from service — four trainsets from the Orange Line and one from the Red Line — while investigating.
The caution, it turned out, was warranted. Following a series of tests, the MBTA last week revealed that the undersides of the new trains are not turning properly as they accumulate more miles — an effect that officials now say played a key role in the March 16 derailment.
