As a teenager, in the 1940s, I stayed with my folks at the Fred Harvey Hotel in Gallup, New Mexico. I pondered about why the flickering (more noticeable from the corner of your eye than looking directly at it, then realized the power supply was no doubt from the Santa Fe Railroad facilities adjacent, probably installed years before Gallup had commercial power.
I'm not sure about the relationship to temperature. This was in the middle of summer and there was certainly no drop in the temperature.
(Fred Harvey and the Santa Fe Railroad were associated from some time in the late 1800s.)

[TELECOM Digest Editor's Note: Remember also the "Harvey Girls" who were like 'stewardesses' on the Santa Fe trains and the 1940's movie about the Harvey Girls, and they were always singing that song about the railroad ... how did it go? Something about " ... my day, and the Atchison, Topeka and the Santa Fe ..." It was a very famous movie in the 1940's and a very popular song. PAT]n
