The invention discloses a locomotive positioning method and system. The locomotive positioning method comprises the following steps: determining the state of current positioning environment; when an LKJ is in the monitoring state and satellite signal is available, obtaining the position data of the LKJ and the position data of a GPS/BD, wherein the LKJ positioning manner is used as the main manner, and the GPS positioning assists to rectify deflected positions; when the LKJ is in the monitoring state and no satellite signal is available, obtaining the position data of the LKJ, wherein positioning is performed by the LKJ manner; when the LKJ is in the non-monitoring state and satellite signal is available, obtaining the continuous preset number of GPS coordinate data of a locomotive, and the locomotive is positioned according to the GPS coordinate data; and when the LKJ is in the non-monitoring state and no satellite signal is available, positioning the locomotive by adopting a speed-measurement positioning method and a dead reckoning method. An LKJ positioning method and a GPS positioning method are combined, so that the problem that the locomotive cannot be accurately positioned in a whole journey is solved, and the locomotive positioning method is continuous in positioning, and high in positioning precision.
