在我国城市轨道交通的规划建设中还存在很多不科学的地方。在轨道建设中,应该把市区线和市郊线区分开,因为市郊轨道和市区轨道有很多完全不同的问题。无论是技术路线的选择、轨道的敷设模式,还是机车车辆的构造,在进行市区轨道和市郊轨道交通的建设时,都应区别对待,做出合理的选择。
There are still many unscientific places in the planning and construction of urban rail transit in our country. In orbit construction, the urban line should be distinguished from the suburban line because there are many totally different problems in the suburban or urban rail. Whether it is the choice of technical route, the laying mode of track or the structure of rolling stock, we should make a reasonable choice in the construction of urban rail transit and suburban rail transit.
