Incidentally, the window you see on the left side of that shot is where the other RailCam is located, in the bay window of the meeting room where SFSFC holds many of its Board meetings.
As luck would have it, while I was composing this message, I heard a horn, and clicked through to see an eastbound Capitol make its station stop at Centerville. (If you care to click through, the train arrives around frame 0928081913.)
