I took the opportunity of a meeting-free morning yesterday and was able to see and ride both of the two car Type 9 sets during the AM rush. Only the third time I'd personally seen Type 9s in service... they're not out at the times I'm usually using the Green Line. They're pretty quiet and seem to have a nice ride quality to them. Those doors are annoyingly slow though, both opening and closing. I suppose it's "safer", but I remember having a very firm respect for the guillotine-chop quickness of the Boeing doors. And even more intimidating were the 01400s with their exposed outside actuator arms. No need for warning beepers or anything like that, just listen for the loud screeee*SLAM* *clunk*
