Does the distance between substations affect the efficiency of electric trains?

Click For Summary
The distance between substations significantly impacts the efficiency of electric trains, particularly in DC systems where resistance increases with distance from the substation. As trains operate farther from substations, efficiency declines due to higher resistance in the overhead wires and rails, which serve as the return path for current. High voltage systems, like the 15kV used by the ICE, are designed to minimize these losses, and scheduling techniques can optimize energy transfer between trains. Despite concerns about resistance and efficiency, electric trains are favored for their higher torque, lower emissions, and ability to regenerate energy during braking. Overall, while electric train systems face engineering challenges, they remain a preferred choice in many countries due to their operational benefits.
