Culver Line |

Posted by randyo on Wed Nov 20 02:35:40 2024 I have several questions about the Culver Line that I hope someone out there can answer. There is a tower at the south end of the northbound platform at Ditmas Ave. Most likely it was intended to control the switches Ditmas and 18th Ave. Was there ever an interlocking machine installed there or was the only machine controlling those switches, the one in the Church Ave tower? There is also a tower at the south end of the S/B platform at Ave X probably intended to be designated as “TowerC” till the current Tower C was built in CityYd. Was that tower ever in use or has it simply been vacant all the time it has been there and since it was there already, why wasn't the Tower C interlocking machine installed there instead of constructing a brand new building? The (probably former) tower at Kings hwy is also a mystery. Most of the BMT GRS interlocking machines were wooden cabinet encased model 2s yet the interlocking machine at Kings Hwy is (was) a metal encased GRS model 5 which also displays signal and switch indications differently from the BMT machines. The model board is (was) also typical IND style rather than a BMT style model board. Now if there was originally a model 2 machine, that had to be replaced, why was it replaced by a conventional lever machine instead of push button NX machine which was state of the art at the time of the IND takeover? Is it possible that there were no switches at Kings Hway till subway trains started operating on the Culver and switches were needed to short turn them there? That could explain the existence of the model 5 machine which was state of the art at the time subway trains started operating on the Culver. |
