Diesel locomotives and electric locomotives can be made more and more powerful in turn.
To increase the power of diesel locomotive, the power of diesel engine must be increased, the power of generator must be increased (diesel locomotive is driven by electric motor after power generation to drive the locomotive), and the fuel tank must be increased.
Electric locomotive, as long as the power line allows, do high-power motor without any problems, there is no volume limit (relative to the locomotive volume).
In fact, there is environmental pollution, but for the electric locomotive, its energy source in the power plant, can be centralized regulation, regardless of the head size and weight restrictions, regulation more fully, relatively small pollution.
Advantages in terms of
Diesel locomotive has no sensory advantages compared with ordinary ones, but it is a good railway traction solution for regions with high transmission costs.
Electric locomotive is a symbol of modern transportation industry, Japan's Shinkansen, the star of Europe and other high-speed trains are electric locomotive, quiet, smooth, high-speed, comfortable is its advantage. Especially suitable for passenger transport
