Abstract:During the serious competition of passenger traffic market in recent two years, the raising speed on existing railways was the key for railways to convert the failure into success. The specialties of raising speed by using tilting trains on existing railways abroad, as well as the operation achievements by import the “New Speed" (X2000) titling trains running on the Guang-Shen Railway, are described. Finally, it is suggested that "the feasibility research of applying the tilting trains on Long-Hai and Jing-Guang Railway Lines" should be established and the operation tests by renting the tilting trains should be put forward also.
