It is shown from the results that the acting force and vibrating acceleration are increased due to its axle load, however, the dynamics interaction between 25 t load wagon and the turnout can be improved by the rubber stack in its axle box, especially in the index such as derailment coefficient, reduction rate of wheel load, opening size of tongue rail and point rail, which is almost equal to the dynamics of 21 t axle load wagon.

结果表明尽管轮轨力和振动加速度因轴重增加而相应增大，但由于25t轴重货车在轴箱处采用橡胶堆，使它与道岔之间的动态相互作用有所改善，尤其是脱轨系数、减载率、尖轨和心轨前端开口量等指标上，与21t轴重货车引起的系统振动值基本一致。

Buyers should be aware that the property adjacent to the outer rail of the lower prices and as a result of light rail through the convenience, but it should be the corresponding transport costs and time cost.

The train positioning technology based on absolute position encoding is proposed. The absolute positions of the rail track are encoded with the m sequence. The biconditional markers placed on the rail track are detected sequentially by the train-borne reader. The exclusive position code consists of the binary information in the shift register. The absolute train positioning information can be extracted by decoding this position code.

利用m序列（最大周期线性反馈移位寄存器序列）对轨道线路上的绝对位置进行编码，当列车在线路上运行时，通过车载阅读器顺序检测设置在轨道线路上的二值标记，在不同位置上读到的标记在移位存储器中构成唯一的位置编码，以此位置编码值作为地址与车载阅读器所处位置的坐标信息相对应，就可以实现列车的绝对定位。
