What happens in the driver seat when you pass through the dead sections! 

"Ding- Dong- Dang- ♪ From here, it is an dead section."
Have you ever heard something like this vaguely on the Seoul Metro Line No.1?
This dead section was created because the power supply method of Line No.1 uses direct current of 1500V underground and alternating current of 25000V above ground!
Today, as we passed through that dead section, we'll briefly see about what the driver does at the driver seat.
In film, I had driven Seoul Metro 1000 VVVF series, KORAIL 311000 EMU.
I recorded this film at 'Hmmsim metro'.
