Marka la eego cutubkan ku saabsan tareenada xawaaraha sare ee Japan, imisa gawaarida ayaa leh tareenada ugu dheer?

Saldhigyadu si la mid ah ayey u dhaadheer yihiin si ay u qaataan tareenadan. Qaar ka mid ah tareenada xawaaraha sare ee Japan waxaa loo tixgeliyaa Shinkansen, halka tareenada kale ee xawaaraha hoose ee maglev (sida khadka tareenka maglev Linimo ee u adeega bulshada maxalliga ah ee u dhow magaalada Nagoya ee Aichi, Japan) waxaa loogu talagalay inay beddelaan nidaamyada gaadiidka degdegga ah ee magaalooyinka caadiga ah. https://en.wikipedia.org/wiki/Shinkansen
