MAGLEV train capable of 3,500 km h clipnabber com

between the wheels and the track the solution is to take both these factors out of the equation it sounds like science fiction but trains that do just that really exist and they’re called maglev which stands for magnetically levitating trains there are no overhead power cables because the power source is built into the track there’s no friction from the wheels because well there aren’t any wheels the train is designed to float ten millimeters above the track so the only resistance it has is air resistance which makes this train fast very fast here at the transrapid test track in northern Germany they’re testing a technology that they hope has the potential to take over where the tgv meets its limits with enough speed not just for intercity but for intercontinental travel but like so many record-breaking trains of the past not one but two rival operations have been battling it out to turn this technology into the world’s fastest passenger service the German transrapid system and the Japanese junior maglev maglev trains are all about magnets and magnets have two poles north and south and when the facing poles of each magnet are the same like in this instance north north they repel like so the Japanese junior maglev system uses this force to lift their trains magnets on the train face magnets with similar poles on the track and the train rests on the repulsive force as if it’s sitting on an invisible cushion like so japanese maglev trains have reached speeds in excess of 580 kilometers an hour using this system but the technology is still confined to the test track they’ve never managed to turn it into a commercially viable passenger train while the Japanese system uses the repulsive force of magnets the German system makes use of attraction but it’s no use having the train sticking to the tracks the trick to hovering is to use electromagnets now an electro magnet is just a piece of metal with wire coiled round is like so when you put some current through that wire like this it’s attracted like so when you switch that current off it drops attract drop and so on and if you were to switch your electro magnet on and off fast enough like this device does automatically you can defeat gravity attracting and dropping so quickly that metal objects like my toy train here appear to hover incredible I don’t know about you but I think that’s pretty damn amazing and that’s magic the transrapid has massive electromagnets in here that’s it under the track and when the power is switched on power on bitter the magnets are attracted to the track and now the Train the whole train is floating in mid-air ten millimeters above the track with magnets at the side here to keep it steady a completely separate system of magnets built into the test track create a moving magnetic field that pushes the train along with it just like a surfer riding an invisible magnetic wave and this makes the system very efficient because you only need to switch on the bit of track that the train is running over now that click means that this section of track has just been electrified or energized and that means the Train is just about to go past and it’s just as impressive from inside the Train we’re now approaching the fastest part of the track let’s go and take a look and see what speed we’re actually doing it might go up here and just check the driver screen and we’re doing over 300 km/h we’re still increasing speed now it’s from a 325 330 that’s already faster than the tgv and we’re still picking up speed very exciting it really is we look out the front we can see that we really are moving the sensation of speed is phenomenal look at that when approaching the top speed 390 400 we are at 400 kilometers an hour that speed you could go right across Europe from Paris to Moscow in just six hours on october the 11th 2003 the Germans got one up on the Japanese when a 30-kilometer track between the city of Shanghai and its airport opened its doors to the public using the German transrapid technology this billion euro project became the world’s fastest passenger train regularly topping 430 kilometers an hour this is a fantastic piece of kit but countries aren’t exactly queuing up to take all this technology the problem might have something to do with a cost somewhere in the region of 50 million euros per mile to create a maglev system unlike city of Truro and the tgv it seems that for maglev simply being the fastest isn’t going to be enough maglev is going to have to get an awful lot faster and in theory at least that’s already possible by building vacuum tubes for maglev trains to run in speeds in excess of three and a half thousand kilometers an hour would be possible making the trip from London to Tokyo a jaw-dropping three and a half hours now that really would be massive speed you
