Correct...sort of.Rockefeller Center Tower is fully automatic and unmanned. What you punch is what you get, and for trains merging, it's first come, first serve. Fifth Avenue Tower is no more. Fifth Avenue interlocking control is now with Queensboro Master Tower. It's monitored, but left in full automatic mode, and not touched. Under normal circumstances, train must punch to get a line-up. But on weekends, with no Sixth Avenue Line service, it's likely they simply fleet the line-up in so that no (E) trains punch wrong by accident. As for why the home ball was at danger with no train there, I believe that's a quirk in some new-tech interlockings. There are signals near interlockings on the (7) line where, with no trains present, it's red, but will clear off once a train passes a trigger point. The holding lights are controlled remotely by the dispatcher at Queensboro Master Tower. However, they should come on automatically when there's a train in the station, and the leaving signal is red. Oh wait, I forgot. Fifth Avenue Tower is closed, but it's possible the Tower Operator is working out of the new Fifth Avenue Relay Room for the time being. I'm not sure. I *really* to pay a visit over there. |
