Even better, we could also put cables above the train and connect them to an even bigger diesel generator located somewhere close to the railway. That would make the locomotive lighter and the energy production more efficient. Better yet, replace the diesel with uranium and you can easily power many trains.
That's not an advantage. You want your loco to be as heavy as possible for traction. If they were switching it to pantograph and it was lighter they'd add iron, or something else to make up the difference
I see you don't know why Caucasus was electrified. Non-electric locomotives were just too heavy and couldn't lift as much as mass as electric could.
