Bad service, Unreliable, you pay for a service for which most of the time you get delays of 20 to 30 minutes.
If you want to rely on this service to go to work, I recommend taking the trains at least an hour earlier than you would normally take.
Bad experience in one month of use.
We want to avoid crowds and there are delays of 30 minutes with a consequent increase in people inside the same train.
