blackout

There was a blackout at the JR Line when I was just waiting for Yamanote Line on my way home tonight. The light went out once I got to the platform at Tamachi station. The platform had become dark during about 20 minutes. I walked up stairs to the entrance gate since the guidance was broadcasted that JR gave the transfer ticket to customers. But after 1 minutes I got the transfer ticket the guidance that Yamanote Line would start to drive soon. So I went back the platform again, and rode on the Yamanote train as always. I thought about what it would be like if I could reached to the platform 1 minutes before. This kind of story is endless.
