The research on low-cost train control system is one of the most important part in train traffic field, using GPS data could realized real-time, safe and reliable train positioning. The train control system special database was studied systematically, the data model and mathematical topology model of data format was established, and the whole seven steps of special database creation were designed. Then according to feature of railway, using adaptive position matching algorithm in rail track positioning, the track was divided into beeline and circle curve, the algorithm base on movable distance frame could realized accurate, real-time and quick positioning. Finally, experiment was done in Sanjiadian marshalling station; the experiment result proves that the special database is valuable and effective for train positioning.
