兰新铁路第二双线于2014年建成,速度等级为200~250 km/h。介绍了国内现有各型动车组的技术指标,对比分析了欧洲标准和日本标准两大系列动车组的技术特点,针对兰新第二双线的环境特点对动车组的特殊要求,并综合考虑各方面因素,建议选择CRH3A型动车组,对其做适应性技术改造,将改造后的新型动车组作为兰新第二双线铁路的运营动车组。
The second new line of Lan-Xin Railway was completed in 2014 with a speed rating of 200 ~ 250 km / h. This paper introduces the technical indexes of existing EMUs in China and compares and analyzes the technical characteristics of the EMU with two major series of European standards and Japanese standards. According to the special requirements of EMU for the environmental characteristics of the second new lane of Lanxin, For various reasons, it is suggested that the CRH3A type EMUs be selected and adapted to technological transformation, and the new EMUs after transformation should be regarded as the EMUs operating the second two-lane railway in Lanxin.
