Posted by randyo on Mon Jan 13 02:50:51 2020, in response to Re: Question About 7th Avenue - 53rd Street Station, posted by N6 Limited on Mon Jan 13 00:55:39 2020. Tracks on branch lines often retain the same numbers that they had on their trunk lines where the branch lines are direct extensions of those trunk lines. The Wash Hts Line of the IND retains the “A” track chaining all the way from 207 St to Euclid. The Concourse line which is not a part of the main 8 Av/CPW Line has its own line designations and track numbers which is “C.” The IRT uses an entirely different tk numbering scheme. There are 2 tk numbering systems on the IRT. MOW numbers S/B tks with even numbers and N/B tks with odd numbers just the opposite of the BMT and IND Also the exp tks have the lower numbers while the lcl tks have the higher numbers again the opposite of the BMT and IND. RTO merely numbers the tks 1,2,3, and 4 from west to east but then the branch lines get a bit tricky. 3 tk lines don't number the middle track referring to such a tk simply as “M tk.” On the Bway and Jerome branches the tks are numbered 1,4 and of course M. The Lenox/Wh Pl Rd branch is numbered 2,3 (and M on the 3 tk portions of the line). The tks on the 148 St branch of the Lenox are numbered 1 and 4. The Pelham branch is numbered 2,3 and M. In Bkln, the E/Pky line has the full 1 through 4 tk numbering to Utica. Utica to N/Lts tks are numbered 1 and 4 while the nostrand Av branch tks are numbered 2 and 3. Free standing 2 and 3 tk lines that are not branches of a 4 tk trunk line are merely numbered 1 and 2 with M where applicable like the Flushing line and the former Manhattan els. As you can see the NYCTS track numbering system can be a bit confusing even for the more knowledgable buff. As an addendum to the aforementioned, the Dyre Av Line tks are numbered IND style since when it was first opened by the B of T it was operated as part of the IND despite using IRT cars and being shown as an IRT line on the Hagstrom maps. It was done partially because the purchase negotiations were started before unification so it would have logically been an IND line and also because the line’s acquisition provided the B of T with a possible Bronx branch to the SAS which was still under consideration well into the 1970s before the city’s fiscal crisis. |
