Pre-GOH R-46 Questions |

Posted by SilverFox on Fri Oct 6 06:53:43 2006 Seeing this image on nycsubway.org brought back several memories I had about R-46 cars pre-GOH. First, there was always a weepy background "whine" that was made by these cars that was not noticeable on any other car class. It was very distinct -- almost electronic in sound -- when the compressor was off, and stood alongside the compressor noise when the compressor cycled on. What was that? It wasn't the microphone, because this whine was external. What about the GOH process eliminated that whine? Second, when the brakes were released, the escaping air left with a distinct whistle. What about the braking system had to be changed post-GOH that eliminated the whistle? Side question: The R-44s pre-GOH had the same braking system as the LIRR M-1s. Why was the braking system changed on the -44s but not the M-1s? The controller stand on the pre-GOH -46s almost looked like the dashboard of a space ship, with numerous buttons, lights, switches, dials, and what-have-you. The controller handle was very distinctive as well. After GOH, the entire stand was replaced by the Cineston (?) controller and had maybe one or two other buttons on it. What was the reason for this change? What was the reason for removing the glass partition at the door breaks of the -46s but not the -44s post GOH? If anything, this feature was a touch of class in a classless system. When did they add the springs to bridge the car ends on the R-46s? I know it was pre-GOH, but sometime after 1980, apparently. How many R-46 trainsets were retained by the Jamaica yard at the time the R-10s (seen in the background of the photo) began to infiltrate the Queens Boulevard lines? My recollection of those R-10s were not as the speedsters others have called them, but filthy, plodding, breakdown-prone messes that desecrated stations upon their entrance. I was only about ten years old then, to wit, so my recollections may be wrong or biased based on the few times I've ridden them with my Dad, but I don't think I'm mistaken. When were those R-46s returned in toto to Queens Boulevard? 82? 83? Thanks! |
