MBTA in other media (ex-MBTA in the movies)

In the Syfy version of Being Human, which is set in Boston but filmed in Montreal, a couple weeks ago the episode featured a scene shot outside, featuring a shot IIRC an MBTA commuter train going over a bridge...first I've really seen that they've actually shot on location.

I don't know the location well enough, but I'm guessing it was the bridge by Wellington.

I was watching Grownups 2 on the train (yes I know its a eh movie but mindless). The CR has a prominent spot in the beginning. Anyone know what stop they were using in the shots?

In That's My Boy, where is the scene shot in which one of our commuter trains goes thru the background scene?
