I am leaving Lille by train tomorrow morning at 10am. I arrive at 11:17am at Gare du Nord in Paris and will take the next SNCF train to Auxerre from Paris Bery at 12:38 so I have just over one hour to go between stations.
Can you confirm if this is right- I plan to : Take the green/blue line D direction Malsherbes/Melun. Get off at Gare de Lyon then take purple line 14 to Bercy the next station. This is becasue Line D does not stop at Bercy. From the metro at Bercy, do I follow the signs for Les Grand Lignes? I hope there is a lift or escalator as I have a heavy suitcase.
