Why does the number and type of cars vary from one train to another?

To optimize the use of rolling stock, we plan the distribution of train cars on a monthly basis according to ridership. For your comfort, we adhere to a standard that allows for a maximum density of two standing passengers per square metre, with a maximum standing time of 25 minutes.

To make boarding easier, the number of cars in the next train is announced five minutes before the train’s arrival on the dynamic display panels.
