how much electricity do trains use

Best answer

With full flights and the latest airplane designs,they can do it at less than1.5 MJ/pkm. Of course,public-transit trains are far superior: At high passenger loads,the best subways need less than 0.1 MJ/pkm. But even in Tokyo,which has a dense network of lines,the nearest station may be more than a kilometer away,too far for many old people.

Electric trains are preferred when constructing a high speed rail network, as they are the most efficient, and have a superior power-to-weight ratio, and ease of maintenance. Electric trains operates by collecting current either from a DC third rail or overhead power lines.
