All trains of the Odakyu line were stopped for 2 hours due to lighting striking one of the trains between Izumi-Tamagawa and Noborito station.
And amazingly a youtube user uploaded a video of the lightning hitting an Odakyu line train (incident at 1:20):
The lightning had burned a part of the train but no passengers or workers were reported injured by the lightning.
The video has reached nearly two million views. And it makes one awesome gif.
