巴黎冷知識(shí)：巴黎的地鐵很爛，特別是13號(hào)線

The Paris Metro system doesn’t announce their steps like most major cities. So don’t fall asleep on your commute – who knows where you could wake up! The most popular way that locals get around Paris is by their extensive Metro train system. Around 5 million people per day use it, and after Moscow, it’s the busiest underground network in Europe. Line 13 is perhaps the least-appreciated line of the Métro by riders and is the object of a number of criticisms on part of its constant overcrowding, especially north of Saint-Lazare where the line splits in two, leading to reduced frequencies. It is not rare for passengers to wait for several trains to load before being able to board due to the sheer volume of users.?
