LIRR SAYVILLE CP "CROSSING PREDICTOR" SIGN
|The signs are "Crossing
Predictors". They are used to predict the speed of an approaching
train so the gates are not in the lowered position for an extended period
of time. Any train that reduces its speed within these limits must
approach each crossing prepared to stop. This does not apply to
trains stopping at Sayville station.
RR signs on the right-of-way with "END CP" at Sayville, NY. CP for crossing predictor, a different signal system being used at Sayville to help manage the length of time the gates are down. This simply alerts the engineer to the limits of this system in operation; in both directions. These signs are after the second grade crossing going east from the station (Lincoln Ave.) about 200' and another westbound of Sayville after Cherry Ave.
This device provides consistent warning times for crossings under the
conditions of varying train speeds. These were installed at several crossing in the Sayville area in the 90's.
That was one of those locations that if the train was travelling at a slower than MAS speed, the gates would not come down until the train was much closer to the crossing than at the other crossings on the Branch..

"Delay in Block" is to remind an engineer, that had a clear signal when arriving at the station,
that after the dwell time at the station the next signal may, during the delay, have changed to
a more restricting aspect so the engineer should proceed accordingly.

Yes, that is a 12 car marker; so an Engineer with 12 cars would know where to stop at Bay Shore (which, ironically enough, is a 12 car platform).
That could sound like a silly answer, but keep in mind as other stations got done over (high level, etc.) Bay Shore was left alone since it had been raised years ago.
For the Cannonball, Westhampton is still the first stop after Jamaica...Westhampton, Southampton, Bridgehampton, East Hampton and Montauk only every time.
No, they never make a Bay Shore stop...I was simply trying to draw a parallel between Bay Shore having 12 cars for capacity and the Cannonball on its heaviest days having 12 cars.
Why was the platform built for 12 cars?

LIRR, uses remote controlled interlocking. For instance, as it pertains to PD tower interlocking in Patchogue (MP 53), further east of Sayville is a point controlled by PD tower where the 2 tracks merge into one, and that is simply called "Y", remotely controlled by PD Tower. Proceeding east with single track (Bayport/Bluepoint) before it expands back into Patchogue, which was a major terminus (roundhouse, turntable, etc. back in the 1920's).
