Strong motion stations have been constructed as a part of earthquake early warning system for high-speed train in China. They are deployed near railways and influenced by train-induced vibration. Then, picking seismic phase, estimating azimuth and extracting predominant frequency become difficult in this scenario. These procedures play a crucial role in locating earthquake, estimating its magnitude and then providing reliable warning to trains. In this paper, instantaneous mixing model was used to describe this problem and show that this influence could be removed by independent component analysis utilizing double sensors.
