Posted by randyo on Tue Sep 16 17:28:35 2014, in response to Re: Tuscarora Almanac - September 14, 1964 - The Book of First Runs, posted by SelkirkTMO on Tue Sep 16 16:25:58 2014. That's one of the reasons why the 1962 built Cambridge/Dorchester Boston cars were ordered with PCC type incandescent light fixtures. According to an MTA rep, the agency felt that there was no satisfactory polarity reversing apparatus suitable for on board fluorescent lights at the time so incandescent lighting was specified instead. Actually, the polarity reverser on the NYCTS SMEEs was on a timer that was supposed to reverse every half hour. If it failed to reverse and the tubes got dark at one end, we were supposed to reverse the polarity manually. By the time of the R-42s it seems that some sort of DC to ASC transformer had been developed so those cars no longer had a manual polarity reverser. Even that didn't work so well.As for GE no longer manufacturing green fluorescent tubes, They weren't the only game in town and I'm sure wither WH or Sylvania would have been only too glad to satisfy the market. |
