Ever since 1994, the evaluations made by expert have proved that the wheel/rail approach for the Beijing-Shanghai High Speed Railway is feasible. However there were three academicians who proposed in 1999 that China was not suitable to develop wheel/rail type high speed trains and great efforts should be paid to development of maglev trains. Then what are the reasons for almost 10 countries and regions in the world that have constructed or are constructing or are planning to construct this type of high speed railways and none of them have constructed a maglev line in real revenue service so far. And in particular why there still exits a big debate on the development of maglev even in Japan and Germany that have long-term test and research experience. For the latter question, the three academicians have the following explanations： The superiority of maglev system can not be brought into full play due to the fact that the distance from the capitals to major cities is relatively short, the high speed highway network and the wheel/rail type high speed railway network are already available, and they do not feel any urgent needs. The author holds that the crucial point, which is a decisive factor, is that maglev system is rather poor in economic benefits and it is by no means perfect technically. The paper also points out that the maglev system has no superiority over civil aviation and high speed railways in terms of technology and economy except that its speed is higher than wheel/rail type railways. Therefore, the so-called “technical leap-forward”，is hard to find ground. The author proposes that it is better to carry out feasibility study of follow-up nature with regard to the application of maglev system no high speed railways. It is not appropriate to spend several hundred million yuan to build a test section. It is essential to approve the wheel/rail type Beijing - Shanghai High Speed Railway at an early date.
