Solution but you avage train engine couldn’t possible fit on a bogey so they had to come up with a whole new motor well more than with in order mount the motor on the bogey you have to reduce its size that they and more importantly it’s matt form us the new moters have to be a third of the weight of the TGV motors a lighter motor means more speed engineers had to completely rethink train Motor design all high-speed train motors have fixed shell called a stator and a spinning axle in the middle called the rotor yeah electricity and magnetism make the rotor move which in turn moves the train but feeding electricity into a rotor has a drawback in Sofia sort of because whenever a current flows their losses which are called just losses the found and elegant solution lining the rotor with magnets here’s how it works electricity from the wires above the train is fed into the stator this creates a magnetic charge discharge interacts with magnets on the rotor causing it to spin around the axle and the new design is paying off big-time each agv motor puts out 1200 horsepower that’s twice the muscle of a Dodge Viper but no one’s going anywhere without a power source high-speed trains get their power from the high-voltage lines running above through pentagram the connection happens through a thin strip of carbon and copper there is a pantograph which is the size of the hand and when the boats are touching together there is electricity flowing through the train and just buy this little contact it moves the trend of 200 meters long 400 ton hey the metal conducts electricity world but he’s softer than the power lines so the lines are strung up ing a zigzag pattern to keep from wearing grooves into the pantograph so in this cable there is about 25 kilovolt coming from the hardwood stage line that is on the the top of the Train and which is distributed to the attraction of the train
