hyacinthus said:I was discussing this casually with a friend yesterday. He told me that to save energy, the passengers had to unlock and open the train doors to alight. However, doors were closed automatically before the train moves on. This is something new to me
I guess most trains stop operation at that kind of hours unless there is sufficient demand for it.
Yes, there is a red button which you have to press when the train stops to open the doors. I think it's right, i mean, sometimes the train is empty and still opening the doors, that's waste of energy . Of course Paris metro is somehow overcrowded most of the time...
