Better driving equipment will improve track adhesion in slippery conditions.
更好的驱动装置能在湿滑的条件下提高轨道的附着力。
It is driven not by the adhesion force from the contact between wheel and rail, but by the electromagnetic force from reaction plate which is mounted in track.
它不是由轮轨间的粘着力驱动，而是由安装在轨道的反应板产生的电磁推力驱动的。
