At stations there are a lot of gates allowing passengers to check in and out quickly. The gates are one-way and the direction is displayed clearly. All gates are monitored by cameras and fitted with sensors. A gate closes when the sensor no longer detects movement. In the event of an emergency, all gates open automatically to allow passengers to leave the station quickly.
In each line of gates, there will be one extra-wide gate. You can use this gate if you are travelling with a small child, have a lot of baggage with you, are travelling with a dog or are using a wheelchair or wheeled walker, for example.
