Abstract
A rail-guided vehicle is capable of accurately determining an abnormality of a position of rail peripheral equipment. The rail-guided vehicle travels along a rail. The rail-guided vehicle is provided with: a vehicle body including a body part and a traveling part; a light projecting/receiving sensor and contact type sensors provided in the vehicle body that each detect a position of rail peripheral equipment; and a length measuring sensor that measures behavior of the vehicle body at the time of detection of the rail peripheral equipment by the light projecting/receiving sensor and the contact type sensors.
