Yes,

The signal posted in the link looks like an NYCT signal. :wink: I thought that the LIRR was using simple signals for interlocking only. But the signal is a normal red, yellow, green, perhaps because of the connection to Harold Interlocking ?

I too wondered about the use of that type of signal head. But it is similar to what's used in the Penn Station tunnels. I'm hoping that the new LIRR Reduced-Aspect Signals are only going to be used on the less heavily travelled eastern part of the railroad. We should know in the next two years or so with the completion of ESA and the Third Track Project in Nassau County.

There's a post by backshophoss on Mar. 29, 2019 that reduced aspect wayside signals will be installed in the ESA tunnels. I haven't seen anything that indicates what these aspects are--are they the same as on Metro North, or different? (There's an amber light on the signal shown in the link, but not on MN.)

Duplicating Metro-North's simple signals would have been the way to go, but LIRR had to re-invent the wheel. They came up with their own set of color-light dwarf signal aspects that look like none ever seen before. I'm told the train crews hate them. There's a chart floating around out there. Try searching Google; I know I've seen it.

Why is the LIRR using reduced aspect on the ESA for a few mile and must switch back to normal signals...
  by Backshophoss
 
Harold is an Amtrak interlocking,uses CPL and color light signals with NORAC aspects
LIRR seems to use RAS style signals for temporary installations and the ESA trackage,LIRR might change all signals to RAS over time,
to get a standard signal across the RR.

I don't think LIRR uses RAS for temporary installations. You're probably thinking of pedestal signals which display conventional position-light aspects on a smaller low-mounted set of signal heads. Those are used during construction projects and for permanent installations where space is limited. The only place RAS are in use so far to my knowledge is between Farmingdale and Ronkonkoma.

I've been scouring the internet for an answer, but I can't find it, so I ask here: How long will it take a train to reach GCT? It's currently scheduled 10 minutes between Woodside and NYP. What will it be from Woodside to GCT?

All sorts of unanswered questions on ESA. Back in 1996, LIRR gave a tour of the east end of the 63rd St LIRR tunnel to the ESA Citizens Task Force,of which I was a member. I asked an official questions. I walked away thinking they hoped for a 2006 opening, with Port Jeff riders transferring across the platform at the then planned Sunnyside station / transfer point. That will never happen. I've since asked LIRR how we would transfer - no answer. One might suspect that the transfer for some trains from diesel country will be so slow and onerous it will only be worth it in avoiding paying a subway fare. As to your question, it shouldn't take long, especially given brand new track and PTC, etc. But back in 1996 I asked another question - why couldn't LIRR diesel trains go direct, and they told me that the tunnel was about 3 inches not tall enough. Other things I've heard since suggest that there are spots with very tight clearances. It makes me wonder why they did not design the DE's, DM's, and C3's not to fit - except for other possibly planned clearance problems. SO I wonder how many problems that would make for much slower transit to GCT may exist. Does anyone have any knowledge here?

One thought, there was no East Side Access when the current diesel equipment was ordered. While it is true thst the tunnel existed, it was a tunnel to/from nowhere.

They were never going to run any DM equipment in there, it was always meant for the M-Series (although probably the M-1's, not so many versions later!). As for time from Jamaica into GCT vs. NYP, I'd imagine it would be much better given the traffic competition from Amtrak and NJT at NYP.

Why would they have not retained the option for running DM's and C3's through there? That meant that from day 1 they knew they were screwing diesel country passengers. Of course, from what I've observed, there were at least some LIRR officials (one of them eventually becoming LIRR pres) who still believed that it was all farm country still past Huntington and Babylon. A big part of why they never electrified certain lines, let alone double tracked them.
