The graphite lubricating "flange stick" they showed in that video isn't exactly new to the T. They introduced them as early as 2017 on all the type 8s.Interesting. The MBTA put out a video recently on social media explaining that the Type-10s would eliminate the screech due to some special lubricating system. That makes me think they don't have any plans for addressing it prior to Type-10 rollout. If they did something more recently that addressed the sound, I'm surprised they didn't crow about that, too.
