Posted by randyo on Sun Mar 10 19:38:18 2019, in response to Re: Platform Lengths - BMT Eastern Divisiion routes, posted by William A. Padron on Sun Mar 10 15:21:33 2019. It’s interesting that the MTA didn’t seem to worry about mismatched windows on the R-10s when back in the 1960s, the TA went out of its way to avoid a similar situation when repairing R-27 8217. 8217 lost a battle with a BMT steel in CIYd and the good end of R-16 6494 which had been wrecked at Broad St a few years earlier was used to repair it. The TA somehow found an excess bulkhead door from an R-10 which was a close to perfect match and installed it on 8217. Oddly enough the TA also used a surplus R-10 (or possibly R-9 since those were similar) cab door instead of the good cab door from 6494. It may be possible that the good cab door from 6494 got used for another repair. I don’t know about the 5952, but in addition to the louvered side doors, 3138 also received a slight modification to the control system. The bypass button was moved away from beneath the gauge to the front panel just to the right of the vision glass above the gauge. In normal operation even with M/M indication working properly, the bypass button can be depressed while the train is moving without having any effect on the train operation. On 3138, if the M/M depressed the bypass button with the controller in an operating position power would cut and the control system would reaccelerate from zero. If the M/M were to remove his finger from the bypass button after the train had accelerated in this mode. power would again drop and the acceleration would start all over again in the normal mode. |
