I don't have exact numbers in front of me, but to the best of my memory catenary height throughout the Green Line ranges from roughly 13' in the subway up closer to 18' or so above the street on Huntington Avenue, but typically somewhere in the 15'-16' range everywhere else.
An F40 is 15' 8" tall, and a bilevel car is 15' 6" tall, so in most cases you're not going to clear Green Line catenary comfortably, if at all.
I kind of rediscovered this topic, so I'll comment now. The catenary on Huntington Ave is 13'6". the panto graph looks like it is almost all the way up. I think the pantograph can extend to 15 feet max. If a F40PH is 15 feet 8 inches, it will defnitely touch the catenary.
Also, there is no way that the catenary is 13 feet in the subway. If you looked up at the pantograph in the subway, it's close to being all teh way down beacause of the low ceiling height. I would estimate that it is 10-11 feet tall maximum.

Car height (standing) from top of rail to locked down pantograph is 11'6", and car height of a moving car is considered to be 11' 11.5", so your numbers above are a little off... per Type 7 Operator's Manual I have.

I know for sure that the catenary on Huntington ave is 13'6" because there are signs that say that so that insanely tall trucks don't get over there. The pantograph looks almost fully extended so the maximum height can't be too much taller.
