That first guy's head is giving a lot of people anxiety. The second guy is giving much higher levels of anxiety to even more people by handling a thin plastic bottle full of liquid nitrogen without protective gloves.

@velderyx2135 You obviously don't know ANYTHING about cars, trains, OR electricity! Brightline Florida trains are powered by Siemens Charger SCB-40 diesel-electric locomotives. They burn diesel fuel to generate on-board power that drives the trainsets, just like the vast majority of freight locomotives in North America. The running rails do NOT carry power. Even if they did (they don't because that would be insanely dangerous), automobile tires are made of rubber (natural or synthetic), which is an INSULATOR (meaning that it does NOT conduct electricity), so there is NO way that a car engine would be affected in the way you assert.

@PixelThorn Thank you for the homework assignment. It was interesting reading.

@thelindblomer Fair points but allow me to elaborate: 1) We have many passenger rail lines in the USA powered by 25Kv overhead catenary, too. The running rails do not "act like ground" -- they ARE GROUNDED. Power doesn't flow far from the locomotive before it goes to ground. Electricity always takes the shortest path to ground. That can be totally disregarded for Brightline Florida, as their trains are powered by diesel-electric locomotives that generate their own power, not electric locomotives, so there's no power going to ground on that line. 2) The voltage of signaling systems is ridiculously low, generally much less than 50Vrms, per IEEE standards. It can be completely disregarded.

@williamstamper442 Not true. Amtrak's entire Northeast Corridor is electrified. Many regional/commuter rail lines are also electrified, especially on the east coast, such as the LIRR, MNCR, SEPTA, and most of NJT.
