I'd think it started in the 1970s with the introduction of the R44/46. It looks to me like those, and all equipment that followed, had slightly tinted windows, to reduce the strain on A/C units. Also, the 44/46/68/68A cars are all do damned big that not much sunlight would reach into the interiors.I'd guess that by the GOH era- mid-to-late 1980s, that was the end of routinely shutting the lights off outside. By then, all cars 9except the R30s) had A/C, and slightly tinted windows. Another factor is florescent lighting- those systems don't do well with frequent on/off cycles. From what I've read on Wikipedia (LOL), any florescent light should be on or off for no less than 3 hours at a time- or its life will be shortened. Turning the lights on and off was probably a lingering practice from the Arnines and down. I'm assuming that everything from R179 and up (and even maybe SMSed R160s) will have LEDs, so the on/off thing will no loger be a consideration. Finally, back in 2005, on a personal railfan trip on the L (R143) I noticed that the crew shut the lights at Broadway Junction, and didn't turn them back on until we reached the junction on the return trip. I noted how unusual that practice had become. Also, the train was definitely a bit dim inside once we descended from the elevated structure onto the flat ROW. |

I too remember lights going out in the summer outside, as late as the 00s. I noticed it happened more often when it was hot outside. But it seemed to be crew's discretion, not some sort of blanket policy, at least as far as I could tell. |

Those are the signs I remember! 9th Avenue had one and I believe Eastern Parkway on the Canarsie line had one as well that I remember seeing. And for some reason I think Marcy Avenue did too but I'm not sure |

A more interesting question is when did they start turning them off. AFIK, pre-WWII cars (BMT Standards and Triplexes, IRT Lo-V and Hi-V, IND R1-9) were not equipped with switches to shut off lights. They started shutting off lights on elevated parts of the Brighton line around 1961 after the delivery of R27/30 cars. |

Posted by randyo on Thu Jan 11 18:04:45 2018, in response to Re: Interior lights, posted by BMT Standard on Thu Jan 11 16:56:23 2018. As I mentioned in my other post, prewar cars on the BMT and IRT did not have trainline control of their lights so they had to be turned on or off one car at a time. The first prewar cars withe trainline control of lights (as well as heat and fans) were the R-1/9s. Lines that operated i bot subway and in the open kept their lights on all the time. When the R types arrived on the BMT and IRT, it was possible to turn the lights on or off on the entire train so it was decided to take advantage of that capability. I believe that the D types and Multis were able to have their lights turned on and off in all sections of the entire unit and I do recall seeing it done on the Multis. Of course elevated lines could keep their lights off all the time during daylight hours except for possibly the Culver Line which went into 9 Ave Lower and the 6 and 9 Av ells running through the Anderson Av tunnel. I imagine in those cases, lights had to be kept on at all times. |

That's interesting- because florescent lights do not like frequent on/off cycling. I know this not only from reading it, but observing it in real life. I'd think that once the cars had florescent lights, it would also not make sense to turn them on or off, unless the mainline els had been saved and we had R39s all over the place (or even on Third and Myrtle Aves.) In those imaginary instances, it might make sense to have them off in daylight hours.I suppose eventually, all cars will have LED lights. Those have no problem being turned on and off frequently- but considering their super-long life, would it be worth the trouble of switching them on and off? |

I remember a sign on the tower at metropolitan Ave in Middle Villagethat had the following: lights on fans on heat on Not sure if the signs were slide in boards, but instructions for train crews. |

Well, on the steels and Qs, fans and heat wouldn’t be on at the same time and I suspect that during daylight hours lights would be off on the el cars and on on subway equipment. |

Turning car body lights on or off on lines that have long periods of either el operation or subway operation would not be all that frequent. If the lights on the Brighton Line were kept off till Newkirk and on for the rest of the trip, it wouldn’t really be a problem. |

That is a point that we deal with in lighting design since the idea of saving money by turning off lights may be eaten into by shortening their life, which adds the cost of the replacement bulb and labor. Modern lighting design encourages the use of sensors which would automatically adjust lighting levels as appropriate. With LED lamping, it is a perfect fit since it has no significant effect on life span . |
