Noel and Dave are spot on:
http://www.trainsarefun.com/lirr/images ... nd1952.gif shows end of double track after Sayville. This hand drawn map was walked and is very accurate as it matches other sources; topo maps, LIRR blueprints, Emery maps, LIRR instruction books, etc.
Dave Keller: "....Wikipedia is filled with data that is provided by people who send in said data..." and he is correct that it has much false/unverified data. In the data processing business and insurance business we tell all our staff to ignore/be very skeptical, etc.

here at MP50 you can see the double track go single.
LIRR c. 1950 map show the single main line turning into two tracks (Ringhouse siding) as Keller indicated.

Patchogue MP53 indicates single track into the double track Patchogue yard.
http://www.trainsarefun.com/lirr/patcho ... lyards.jpg The popular panorama map of the time c. 1904-06 show a single track. They are very accurately drawn. My ex-Patchogue house had the correct windows, porch and shed on the map exact.

Your trying to find a nice section of the LIRR to make a model of. Drop me an email and I'll have a chat with you.
I wrote a magazine article about Oyster Bay:

I have an LIRR modeling site;

Patchogue is fabulous with all its industry, turntable, roundhouse, etc. I have an article to do in the future...
The Bay Ridge Branch has interesting possibilities.
And several fellows are doing the Bushwick section:
