I've been working from home for more than three months. We are walking distances every day for health management. The other day, I had the opportunity to come to work for the first time in a month, so I got off at the station in front of the company and walked to the company. On the way, I found a railroad crossing near Ueno Station. If the alarm is sounding and you think "unusual", why isn't the Ginza Line vehicle passing? The railroad crossing of the Ginza Line, an important subway that runs through Chuo-ku, is extremely rare.
It seems that this is a depot called Ueno Kenkyu District of Tokyo Metro, and the train that departs from here enters the underground tunnel through the slope.
At this railroad crossing, there is a very rare gate that crosses the track. There is no overpass line on the vehicle on the Ginza Line, but instead there is a high-voltage current called "third rail" (third rail) next to the track, which is extremely dangerous if you enter.
