Why is the rear pantograph up and not the front one?
From what some explained - if the front one is up, then the sparks keep falling on top of the front cabin and heats up the cabin. So the rear is up.
Not sure if that is right, since I don't know how much sparks keep falling.
But that's one explanation...

it always seemed like some form of convention rather than something based on scientific principles.
kind of like why India and Europe uses 50 Hz power, while USA and some other countries use 60 Hz; there are reasons that are often offered for the choice, but look deeper and you realize that is nothing more than following of tradition that was established long ago :P
