Bonjour,
At the tube gates, you need to touch in
Then you take the escalators down
When the train arrives, you get in
You take the escalators up to get out.
To leave the station you must touch out.
to touch in / to touch out = action d'utiliser sa carte/abonnement... pour entrer / sortir
to get in = entrer
to get out = sortir
to take the escalator down = descendre par l'escalateur.
to take the escalator up = monter par l'escalateur.
