明白了,相当于国内的火车,但是为什么叫heavy rail,不直接叫train呢?
【在 d***e 的大作中提到】 : heavy weight, higher capacity, more cars, dedicated row
Heavy Rail is high-speed, passenger rail cars operating singly or in trains of two or more cars on fixed rails in separate rights-of-way from which all other vehicular and foot traffic are excluded. Also known as "rapid rail," " subway," "elevated (railway)," or "metropolitan railway (metro)."
