Hmm, viewing the area via Bing
(I know, but it's good enough), could this conceivably be tied in with the proposed double tracking of the LIRR in that area
. I'd like to think that Poscillico is finally getting a siding, but of course railroads are unsuitable for carrying large quantities of bulk construction materials like stone, gravel, or cement. Bing view (probably 2 years old) shows double track (sort of) from just West of the substation off Wellwood Avenue, heading west, the North track forming the bottom leg of the Costal Transfer wye at New Highway, then the siding along the warehouse which ties into a switch west of the east Boundry of Poscillio's property, then the two tracks merge into one track which continues for a bit west till it once again split well east of the Rte 110 bridge. What a odd track layout, this could have been double track out to Wellwood at least. Yeah, I know, west of Rte 110 only the South track looks to be electrified, and I certainly recall during the 1990s strings of freight cars stored along the North track west of the Wellwood Ave substation.
There's enough existing right of way in that area to install 2 mainline electrified tracks plus a third industrial track to service the industries (well industry) around New Highway - now let's see what the LIRR comes up with.
