Posted by randyo on Wed Apr 4 14:21:42 2012, in response to Re: March 31, 1977 - The Last R-1/9 Run In Service, posted by Westcode44 on Wed Apr 4 01:25:16 2012. The puff of air from the variable load valve on SMEEs was a little more muffled sounding than the one from the R-1/9s but it was definitely there. On the BMT, pre R-27s didn't have the interior guard light so was C/Rs were were instructed to listen for that puff of air on the R-16s when checking doors to clear a hanging guard light and/or cutting out a door. R 27s and up (on the IRT starting with the R-22s) there was a blue interior guard light above the crew emergency key switch. Eventually all IRT SMEEs were retrofitted with the interior guard light but neither the R-10s nor the R-16s were retrofitted until the R-16s received the R-44 type door operators. |
