The invention provides a train positioning method and device. The method comprises the following steps: acquiring satellite positioning information and one-dimensional ODO positioning information of a train; inputting one-dimensional satellite positioning information corresponding to the satellite positioning information and the one-dimensional ODO positioning information into a robust estimation filter for information fusion calculation to obtain target position information output by the robust estimation filter; wherein the filter gain of the robust estimation filter is calculated based on the equivalent observation weight matrix. 本发明提供一种列车定位方法和装置，该方法包括：获取列车的卫星定位信息和一维ODO定位信息；将所述卫星定位信息对应的一维卫星定位信息和所述一维ODO定位信息输入至抗差估计滤波器进行信息融合计算，得到所述抗差估计滤波器输出的目标位置信息；其中，所述抗差估计滤波器的滤波器增益基于等价观测权矩阵计算得到。
