tera power leveling, running speed limit must be less than 80 km/h. "Due to the subway train car-body spot welding is, if speed exceeds 80 km/h, has the potential to cause wind resistance, danger train. "To ensure that the subway train transport safety, driving, when metro connection" only hangsThe tail ". In other words, behind the subway train, can no longer connect train compartments, or they might hurt. Due to metro train is connected to the train after the locomotive, traction and braking the train, subway trains must be synchronized to maintain traction and braking. "For example, the front launched a train locomotive, if subway trains in braking, that will be very dangerous,Metro has the potential to cause wheel lock.
