This topic came up on another message board, the platform tracks on GCT's Upper Level and how they were, apparently, expanded over the years.
On an Upper Level track diagram on page 148-149 of the William Middleton book, "Grand Central, World's Greatest Railway Terminal," the first track (easternmost by compass, northern by railroad direction) shown as having a passenger platform is Track 16. The diagram is from the collection of Herbert Harwood and is undated. In the area east of Track 16, starting at the far east end, Tracks 1, 2 and 3 are the Loop tracks; there is a crossover shown from Tk 3 to Tk 4. Tracks 5-9 are stub end tracks without platforms. Tracks 10 and 13 are on either side of "Express Co. Platform." Track 11 stub ends at the north end (compass direction) of the express platform, at about 45th Street. There is no Track 12 shown. Presumably the area Track 12 would've occupied was taken up by the express company platform.
Apparently the tracks available for passenger use were expanded over the years, presumably sometime between 1921 and 1939.
In a 1921 Electric Division ETT there are no passenger-carrying trains shown departing any Upper Level track east of Track 16, the first track to show a passenger platform in the undated Middleton diagram.
However, by 1939 things had changed. Now three tracks east of Track 16 were in use, Tracks 11, 13 and 14.
In the 1939 ETT passenger trains shown departing Track 11 are 75 to Poughkeepsie, 1019 to Chatham and Y386 to New Haven. On Sundays there were six trains scheduled to depart Track 11. In a 1960 ETT there are two weekday trains shown departing Track 11, Y348 to South Norwalk and Y332 to New Canaan. On Sundays 917 to Chatham used Track 11.
In 1939 the ETT shows three weekday trains -- Y372 to New Haven, Y302 to Stamford and 69 to Poughkeepsie -- and one Saturday and four Sunday trains departing Track 13. In 1960 the ETT shows five weekday and one Sunday train departing Track 13.
The 1939 ETT also shows trains originating on Track 14. On weekdays there were two trains, Y356 to Danbury and Y342 to New Canaan. In 1960 Y56 to Springfield, Y362 to New Haven, 95 the Dewitt Clinton and Y144 "Berkshire," are shown departing Track 14, all weekday trains. In neither year were any weekend train shown departing from Tk 14.
There were no passenger trains shown departing Track 15 in any years.
None of the 1939 and 1960 trains departing 11, 13 and 14 show any restrictions as to carrying passengers in the Special Instructions.
