You don't have diesel engine and fuel tank on electric wired train ;) Also, looking at cars, batteries are much heavier than engines and fuel tanks giving same kilometrage. On top of that, fuel tank is heavy only in the beginning of the trip. You can fill up only as much as you need for the trip for better fuel economy. While batteries stay same weight for lifetime. Batteries make sense for manoeuvre trains working ports, cargo train depots etc. Small batteries and recharge frequently.

> "You don't have diesel engine and fuel tank on electric wired train ;)" In some cases you do because hybrid (bi-mode) trains exist too! [1] Although as another commenter points out, they are also working on tri-mode diesel/battery trains.
