Leo, Tom:
Leo’s correct that the “alignment maps” would be your best resource, Tom. These are more formally known as “Valuation Maps”, being done by railroads for property tax purposes, and were generally audited for accuracy by the taxing authorities
having jurisdiction (often local, county, and state level) over the railroad’s various properties. Because the railroads paid real property taxes levied based on these drawings, they kept them up to date through re-alignments and especially through abandonments
(most of which were undertaken to reduce the railroads’ tax obligations.)
Val Maps typically show the surveyed centerline of the track, the land around the track owned by the railroad, any buildings, bridges, and other property improvements owned by the railroad, water features, and often some adjacent cultural
features such as streets, and sometimes buildings owned by customers served by the railroad. The standards for these drawings are survey grade, highly suited to depict the size, footprint, and orientation of included buildings. Typical scale is 1” = 100’,
with each map covering roughly a mile of line. Elevations and contour lines are typically not provided. The “station values”, i.e. "chains” of 100’ length, plus residual feet, from the survey origin point of each line are provided, as well as “match markings”
that show the previous and next Map along the route. I have attached a New Haven (actually a predecessor road, the Central New England Ry) Val Map as an example. This example is located in Poughkeepsie, NY, at the Eastern landing of the Poughkeepsie Bridge
over the Hudson River, dated 30 June 1918. Note that this is one of over 400 Val Maps the NH maintained for its taxing authorities in four states—obviously a gargantuan task to generate in the first place, and then to maintain in perpetuity. Val Maps for
track running through the boonies are far less interesting than Val Maps for track running through towns and cities, or in areas with a lot of sidings or a significant interchange.
One can often find Val Maps on eBay, though it’s rare that you can find a specific map that you might want. Buying them individually is very expensive, though they are pretty, as those available are typically blue-line reproductions of
the railroad’s vellum master sets. One seller offers CDs of digitized map collections; each CD addresses one or more railroad fairly comprehensively; I have bought his products for several Eastern roads, and have been favorably impressed. This is several
orders of magnitude less costly than trying to comprehensively collect individual maps. The caveat is that the maps on a given CD may not all be from the same survey time frame. And this is Leo’s critical point: in order to get what Tom wants, he needs
the appropriate Val Map dated between the time the alignment he wants was established, and the time it was altered, by the railroad.
Beware that all blue-line reproductions darken rapidly in direct sunlight.
Best,

An older station or track alignment map would show these spurs. I just checked and mine are too new. I’ve seen one from the 30s that showed these spurs. I just checked members only side of BRHS site and the alignment charts there are too
new.

I have been trying to find a map aerial view or picture of the north side of the Q main line between La Grange Rc.
and Stone Ave. I am looking for the sidings going to Lord Lumber and the one going to the meat warehouse crossing the Hillgrove Ave and the Street Car track. I can't believe as a railfan I don't have my own picture.
