Why does the orange line on the front curve upward? If it's supposed to
represent a safe distance from zap, shouldn't it curve downward if
anything?

Isn't it just decorative?

No, it's a warning line to indicate the upper limit of safe working
under a live overhead wire. You see them on any train that operates
under the wires. See the link I provided earlier.

As far as I can see, you see them on any train whether it operates under the
wires or not.
