I'm from Boston and have a question about your Boeings. I understand that they are no more but how did the center doors work, was the doorway always platform level or did they go up and down when either in the tunnel or out of the tunnel? Any info is helpful and thank you.
IIRC and it's been a while since I rode in a Boeing but I believe the center door had stairs that raised or lowered depending upon street level or platform boarding.
I have seen and took a picture of a Boeing LRV numbered 1320 at Muni Metro's light rail maintenance/yard facility at San Jose and Geneva next to Balboa Park BART Station.
