The interlocking here didn't exist until Shea Stadium station was nearly 50 years old. The interlocking first went into service on March 21, 1988. Today, the interlocking, which is just over six miles away from Long Island City, is fairly simple in nature.
There are two crossovers which are quite a distance away from each other. The first one goes from Port Washington track 2 (the eastbound track) to Port Washington 1 (the westbound track). A little further down the line, there is a crossover from track 1 back to track 2.
Of all the remaining switches in the diagram above (going into and out of the other two station platforms), only the very westernmost one that goes from Port Washington 2 to track 3 is a part of the interlocking. All of the other switches in the Mets-Willets Point station complex are hand thrown (but they are rarely used so it rarely becomes a problem).
I went into some of the history and the configuration of the Shea Stadium/Mets-Willets Point station itself back in March as the Mets service was about to start up (I would have liked to see trains running to the station this time of year, but unfortunately that won't be the case this year!). But be sure to check that post out also too: you can see it here.
Position light signals still signal movements through the interlocking. There are two special signals that are unique to the Mets-Willets Point station complex. On either side of the station, there is a special yellow light that flashes to signal to the engineers that their train is to stop at Mets-Willets Point. Going westbound, the signal is mounted on the west end of the Flushing-Main Street station platform. Going east, the signal is mounted on a signal bridge as you approach the station. When the signal is flashing yellow, the train is supposed to stop at Mets-Willets Point. When the signal doesn't flash, the station is to be bypassed.
That wraps up this week's interlocking walkthrough. We'll be in a slump of somewhat boring interlockings for the next two weeks or so more, but keep on checking back, we're getting very close to the end of the LIRR interlockings!
Many years ago, the IRT and LIRR had a switch which enabled the IRT to move equipment between the Flushing Line and its Manhattan main lines (via the Hell Gate and E180th St Yard), and also take new car deliveries. The R12 subway cars and Q type el cars, among others, all used it at one time or another.
ReplyDeleteSuch a switch would still come in handy on occasions. If they wanted to move cars from the (7) to the rest of of the IRT they could do so pretty easily by hauling them along the Bay Ridge Branch and then going back onto the subway by Junius Street on the New Lots Av Line.

The connection between the Canarsie Line and Bay Ridge Line was pulled up also.
DeleteIt is the Canarsie Line that has a connections with the IRT Livonia Line.
The connection between the New Haven and the TA in the Bronx in gone too.
Flushing cars are sent down the BMT Southern Division fro Coney Island Yard heavier maintenance, but to swap out, sent up to IND Concourse Yard which connects to the IRT Jerome Line.
Last I heard, you could still connect from the Linden Shops to the Bay Ridge line; it's the direct crossover from the Canarsie line to the LIRR that was removed.
DeleteI'm pretty sure you can't use cars intended for the #7 train elsewhere in the IRT, though, even if you physically were able to move them there, because they've got the trippers on the wrong (B-division) side.
It also looks like it would be pretty easy to connect Track 35 in Corona Yard to Track 1 of the Port Washington branch, and they both use the same style third rails, but what would happen if you tried running a 660 volt subway train on the 750 volt LIRR tracks, I don't know.
Going way back in history, this location had another identity even prior to the 1939 World's Fair. It was Whitestone Junction, where the old LIRR Whitestone Branch (abandoned in 1932) branched off from the Port Washington Branch. I don't know how it was configured but I imagine there must have been a tower and interlocking of some kind, since the Whitestone Branch was electrified and saw a fair amount of traffic in its day.

DeleteTwo minutes of searching and I answered my own question. Whitestone Junction was controlled by JC Tower.
