Why 25KV is used in railway traction system instead of the normal 240/415 or other HT supply |Hindi HD

In this video of Why 25 kilovolt is used in railway traction system instead of 240/415 or other HT supply following points have been discussed Why is electricity transmitted at high voltages? How does the current in a wire change as the voltage increases? Why does the Indian railway use a single phase 25 kV overhead line? Why do Indian railway use 25kv ac instead of 11kv, 440v,220v for OHE? and many more concepts. I would really appreciate if you can give me your feedback after watching this video.
