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. |
