Posted by randyo on Mon Jan 5 16:19:08 2009, in response to Re: Why was 179th St/Jamaica 13 years late?, posted by Chris R16/R2730 on Mon Jan 5 11:50:47 2009. During the years Rockaway Av was used as a terminal, there was a diamond Xover between the exp tracks N/O the station and trains stub ended in the station. Between the exp and lcl tracks in the area of the Xover there are extra colums to support the subway roof to make up for the lack of columns that should have been between the exp tracks but were not installed to allow for the installation of the Xovers. These switches were controlled from Utica tower and if you look at the model board, you can see the outline of the painted out Xovers and the signals. The levers are also still in place on the machine but since they are now spare levers, they are painted yellow. At about what would be the 9 car stop marker on the S/B lcl tk, there is a short section of ballasted type 1 track on both exp tracks where the bumping blocks were located. When ENY first opened, the temporary wooden platforms were removed from over the N/B lcl track only. S/B trains continued on A3 tk S/O Utica to the diamond Xover between the exp tracks N/O ENY. Trains then crossed over to the N/B exp tk and utilizing the diamond Xover between the lcl tracks stub ended on either the N/B exp or lcl tk at the N/B platform at ENY and returned N/B on the N/B lcl track. The last time I was at ENY (now Bway Jct) station, the reverse car markers were still in place. I don't have any info as to when the tracks and special work immediately S/O the station were completed allowing trains to proceed on the S/B local tk into ENY station and relay S/O the station or even if that was done at all before the line was completed all the way to Euclid. Since there was a wooden platform extension just past the bumping blocks to allow passengers access between the two terminal tracks similar to Flatbush on the IRT, it might have been possible to construct an island platform over the express tracks ans use the local tracks to turn the trains but that would have required more complicated rearrangement of the support columns N/O the station and a much longer diamond Xover to span the distance across all 4 trackways and the B of T probably felt that such an expenditure was unnecessary for what was going to be a temporary operation. |
