Managed to work out how to adjust seats. Successfully managed to work my way through the labyrinth of stairs, walkways and some working elevators to access the metro inbetween the train station. Now on the second train on my way to Nogent sur-seine, just hope my host is there to pick me up as I haven’t heard back from her since relaying my arrival to her via whatsapp chat. This train seems as fast as the high speed train. Well it’s goodbye to Paris, it’s train stations anyway.
