I'm confused about the closure dates of Line 6. Could you clarify that for me?
Only stations Dupleix and Nationale on line 6 are closed each evening after 10pm (line 6 trains will simply skip these stations, traveling beyond them on their journey). For Dupleix, these evening closures end on Oct 2 and Nationale, Oct 16.
Otherwise, Metro line 6 trains are operating normally.
Hope this helps.
