when it's cold as hell in Chicago, this video shows that the Elevated metro train puts on one hell of a show of sparks



but see the video, it's worth the effort. I couldn't find a decent video that I could embed, so, instead, you must click through to see it. Sorry about that. Reddit doesn't make this easy

    We had some unusual problems with trolleybus traction some days ago. There was some epic mist in morning, it was just near zero degrees Celsius. The mist settled on the traction and immediately froze in a thin layer of ice, this created an insulating coating between the traction and the trolley poles. So no power on sufficient level or even at all on some road sections. If you stuck with only-electric power one without secondary battery or engine you... stuck in middle of road. I remember only two or three such situations in my life.

    Happily I did ride in double electric trolleybus with auxiliary battery to ride through that no traction road sections so driver just switch the systems and we go forward. Reserve power system, good thing to have.

    I did speak with my buddy about that, he said trains had the same problem that day but they ride with both pantographs up, first cut ice and second get the power from traction. Or they have some type of loop system where they put energy again in section to warm it up and melt ice coating. City trolleybus traction don't have such system or ability to "cut the ice" in from traction.
