Paris to trial all-night metro operation
https://www.metro-report.com/news/news-by-region/europe/single-view/view/paris-to-trial-all-night-metro-operation.html
One of the social issues about Paris Metro is safety. When we visit some stations in Paris Metro, we can hear announcement warning pickpocketing.
In this situation, it will be hard to ensure safety during midnight.
I wonder how they overcome the problem.
