Train automatic stopping controller

Train automatic stopping/stop-position controller (定位置停止装置, Teiichi Teishi Sōchi) (TASC) is the name of a train protection system/automated stopping aid currently used only in Japan. It allows trains equipped with TASC to stop automatically at stations without the need for the train operator to operate the brakes manually, preventing stopping errors and SPADs.
