1 of the passing siding switches(CP East "BH")or a "hold" type signal at Amagasett(CP "AG").
All of the new signals are operated by a "control operator" at Babylon(untill a central DS console is built at JSCC in the future :wink: )
What's the difference between a CP-protected siding and an interlocked siding (like DUKE)? Would the CP-siding not have power-operated switches?

Current LIRR pratice is to install dual-control switches,by throwing a lever on the machine motor disengages the motor,
to allow hand throwing of the switch.
A control point is a "mini"- interlocking, LIRR uses the term "Remote Interlocking" at places like Locust, MS(JJD)1 and MS(JJD)2,for example.
To follow what was done on the Port Jefferson,each new power switch will get it's own name
"BH-1",west end of the siding,"BH-2"east end of the siding,etc.
It is normal pratice in CTC territory that all mainline switches are powered or Electric Locked,meaning the DS or the Control Operator has
to allow a switch to be "operated" and signals set as needed. All of the freight sidings and passing sidings other then BH and SN
will have Electric Locks on them.

Are the signals all going to be color-light? And what will be the entering/exit speeds for diverging routes at the sidings?

The information item in the committee meeting notes doesn't get nearly that specific, but I'd assume they would be like the color light signals that's seen at PD, MS, and SK for uniformity.

This is a guess,25-30 mph,diverging route. :wink:

Finally heard back from the MTA, a "control point" is the same thing as an interlocking, but without controlled switches. So for AG, for instance, there would be a signal there protecting movements, but if they wanted to use the siding, a crew member would have to hit the ballast and open the switch manually.

Since it has been a few years any updates as to how the signal project is coming along?

Late night tonight begins the cutover of the new signalized montauk branch. If all goes well over the weekend, there will be a whole "new" railroad east of SK2.

Will all sidings be remote-controlled from Babylon's tower and will the signals be PRR-style position lights? Thanks.

Southampton and Hampton Bays will be remote controlled from Babylon.
Signals will be placed at those two locations plus Amagansett. All signals are color light.
No automatic signals, cab signals are in effect between interlockings.
All other switches, including Amagansett and everything east of the current Block Limit MY, will remain hand operated, some with electric locks.

On the subject of diverging speeds, does the LIRR use Approach Limited (Y/*G* or PL equivalent) and Limited Clear (R/*G*)? And are the cab signals still just MAS, 30, and 15?

Could you please specify number and location of signals in Amagansett?
Will it look like a fully interlocked siding with six signals and only the switches remaining electric lock?
Or more like just one signal per direction protecting the loop?
What will the procedure for meets at Amagansett be?
Thanks a lot.

Westhampton - No signals. Siding has electric lock switches
Hampton Bays - Color Light signals protecting each switch. Switches are dual control.
Southampton - Color Light signals protecting each switch. Switches are dual control.
Bridgehampton - No signals. Siding has electric lock switches
East Hampton - No signals. Siding has electric lock switches
Amagansett - Color Light signals are in place, but do not protect any switches. Siding has electric lock switches.
Montauk - Color Light signal for westward trains leaving Montauk.

Thank you for the details.

Will the signal locations at Amagansett allow for a convenient use of the siding and its electric lock switches, meaning
- the eastbound signal is west of the siding and
- the westbound signal is east of the siding?

Nope. Both signals are located just east of the west switch.
