WCVB has video of the center section of a new Type 9 buckling at Boylston the afternoon of Patriots Day, which caused monumental delays in part because some riders were kept on other trolleys for close to an hour. The T says all other Type 9 trolleys passed inspection.

Articulated section? Articulation?

From:

Articulation involves placing flexible joints and a rolling floor plate at the center of the streetcar so that the streetcar, with its long wheelbase, can maneuver sharp curves. Any longer vehicle has trouble turning along sharp curves, and a streetcar is no exception—longer buses require articulation as well. With articulation, the vehicle is eased along the curve, making sure that it does not drift over into neighboring lanes or hit nearby objects while it turns.
