Hello Limeuhu12 , I understand that it is between 7 pm and 5 am, I believe it goes until 7 am for Saturday, Sunday, and public holidays.
(The Night GA Travelcard is valid from 7pm to 5am during the week. On Saturdays, Sundays and national public holidays, it is valid until 7am)
I just don’t understand what am I supposed to do if the delay happens during my train trip, do I get off right before the last stop? What if the delay happens right before the last stop? What am I supposed to do?
