The invention provides a train positioning method and device. The method comprises the following steps: receiving a target radio frequency signal sent by a target antenna; wherein the target radio frequency signal comprises the target radio frequency signal strength, the speed of a target train and the antenna distance between a target antenna on the target train and a first antenna; determining the received actual radio frequency signal strength according to the target radio frequency signal strength and the speed; determining a first distance between the target train and a receiving antenna according to the target radio frequency signal strength, the actual radio frequency signal strength and a signal attenuation constant; and determining the relative position of the target train and the receiving antenna according to the antenna distance and the first distance. According to the train positioning method and device, train positioning is achieved through the radio frequency signals transmitted by the waveguide tube, the positioning precision is improved according to the speed of the train and the fixed distance between the two antennas on the train, and accurate positioning of the train is achieved.
