现阶段我国铁路的行车密度已经居于世界前列，行车速度提高的余地又不大，相比之下提高列车重量有着很大的潜力。

It is clear in our county that the traveling density of the railway is very high in the world and it is hard to increase the traveling speed now compared with the huge potentiality of vehicle load.

高速铁路列车速度快、行车密度大，要求牵引功率高，电力牵引成为高速铁路动力牵引的必然选择。

For the rapidity and traffic density of trains on high-speed railway, larger traction power is needed, so the electric power supply is adopted.
