Do trains get hit by lighting if so what happens

Everyone must Rememebr, Electricity follows the path of least resistance.. <br /> <br />Thge human body is like a pack of Resisotrs.. it offers A heck of a lot of ohms Resistance compared to a 5' 11" copper wire wich offers 0.001 Ohms Resistance. Aluminum conducts Electricity at 60% of copper, but if your sitting in your chair The Lightning bolt will most likely not effect you, I have never been in this situation, but i can assure you minimal damage is done. <br /> <br />Water does not conduct Electricity. No it does not. It Requires an additive to do so. Like Pools.. The H2O has Chlorine in it, the more the clorine, the faster Electricity flows throw it.. the less resistance it has.. <br /> <br />IF you cut a wire and remove a 1 inch section of it, then put one finger on one end and another finger, (it doesn't matter what hand, you can use seperate ones if you like) you will get an electrical shock, because you leave the Electricity no other option but to flow through you. Howerever if you don't Remove that Wire, and touch the wires an inch apart, you WONT get a shock because it's easier to flow through copper, or aluminum then it is to go through your finger. <br /> <br />Face it Electricity is lazy, taking the easiest path possible. <br /> <br />Factor this in your on a train, going 50 MPH. Lightning usually strikes the highest point.. is a common misconception.. Lighning will strike Whatever gives of a better NEGATIVE magnetic FIELD. a tree, made of wood, does not give of a Strong negfative magnetic field, however a 25 foot MEtallic Aluminum rod sticking 20 feet in the ground gives of an Excellent negative magnetic field. <br /> <br />Remeebr another thing.. Electricity will do anyhting to get through the ground. it would rather not travel through a lighbulb, it would rather go directly to the ground. <br /> <br />Ever notice That when you attach a Black (live wire) and white (common wire(using the 120 volt AC system)) directly sparks fly for about ~1 to 5 secoindes (based on the maker of youre fuse box, i would recomend Square D before anyone else because it takes a fuse 0.5 secondes to blow) after the sparks fly it dies. yet take the same wires attach them to a light bulb holder and place a light bulb in the holder.. turn on the switch... what happens.. the lgiht goes on.. no sparks???!?!!?.. i'll explain that.. the light bulb Fillement inside (made of Carbon) offers the flowing Electricity .. 18.1 Ohms of Resistance.. compared to our direct contact wich offers 0 ohms of resistance. <br /> <br />Kettle runs on the smae principle except there is a thick NICR wire (Nichrome, Nickel chrome) wire inside.. that rather then conduct Electricity perfeclty like copper, it offers ALOT of resistance and as electricity goes through that wire it heats up.. <br /> <br />so various wires are used for different things, carbon for light, Nichrome for heat and copper for almost perfect conductance. <br /> <br />Remeber 1983? the first metallic aplliances came out back then.. or the first ones with a triple Grounded Prong. that offers an even easier route for Elec. (Elec now stands for Electricity, because i said so) to pass through, Rememebr the white wire is a Standerdized ground that goes back up to the power lines then down a wire along the side of a telephone poll .. the ground wire (GREEN) is the funky center prong on an outlet.. that offers a Direct route to the ground.. so should one of the wires become lose in your appliance and touch any of the metallic parts.. rather then getting a NASTY shock, the electricity would be much happier travelling through the ground wire.. into..well .. THE GROUND! <br /> <br />how does it do so? check near your fuse box... look on your water pipes.. you may see a bare copper wire attached to one of your water pipes.. these are an excellent source of Grounding <br /> <br />is there a perfect Conductor? <br /> <br />Yes, Solid Gold. Gold wire offers far less Resistance then a copper wire EVER could. But unlike most of you, i cna't afford solid gold wiring yet. so cheap copper will have to do <br /> <br />Don't settle for Aluminum!! <br /> <br />that will, over time, loosen itself from whatever appliance you have attached it to. back in the days.. when they didn't have proper grounding.. it used to loosen itself and fall in the metallic box.. (these days they are grounded) the metaalic box (being attached to a beam) the Elec. would slowly find its way to the ground.. thus making the wood, and the metallic box extremely hot. over a period of 5 years or 10.. the wood would combust, and cathc the house on fire. when i say metallic boxes, i mean the boxes that outlets are attached too. the live wire would slowly over time loosen itself, even though it may have been properly screwed in at the outlet , it would loosen, fall, heat up the box.. 10 years later you got ashes for a house. <br /> <br />So proper grounding came in.. <br /> <br />Rememebr the WOODEN rule .. if you expose wood to a 250 degree temperature for an extended period of time( lets say 5-10 years), if one day after that period of time, the temperature should rise to 260 degrees, the wood will cath fire, even though it's normal combustian temperature is 600 degrees or so. <br /> <br />those are some golden rules.. the actual chances of a train being struck by lightning is about <br />0.00000000000000000133 <br /> <br />don't mind cabforward, he wore aluminum diapers as a child, which significantly lowered his Resistance to lightning and must have been struck based on his foolish statements. <br /> <br />those are low ods.. you do have a chance of winning the lottery 8.5 times before being struck by lightning in a train <br /> <br />Because rails already have a posotive charg flowing through them, they offer a significantly LOWER negative charge then any other object around the tracks, such as a house.. or a funky wind thing that are made of metal.. this possotive charge that triggers the block signaling systewm or the RR lgihts, actually in a twisted way prevents the tracks from being struck more often. <br /> <br />the top power line on a poll offers a charge of 7500-25000 Volts. it almsot never gets struck, because it already carries a possotive charge. <br /> <br />Lightning is not attracted to possotive charges.. it is attracted to the strongest negatinve charge it can get from the ground. like a metallic ROD that is grounded... a tree if it has a lot of sap because sap conducts electricity and so on, but you must get the point os ill shut up. <br /> <br />sorry for all the SPelling Errors.
