Transport Notes

Some notes about transport in Paris around this week. There are some lines shut down for maintenance. In particular, I’ve seen signage that:

RER line A (the middle east-west RER line through the center) is closed between La Defense and Auber exclusive (i.e., the western half of its run through the center of Paris) from July 25 through August 23, inclusive
~~RER line C (the southern east-west RER line through the center) is closed between Avenue Henri Martin/Javel and Gare d’Austerlitz (exclusive), July 15 through August 22~~
Metro line 4 (a north-south metro line through Paris) is closed north of Reaumur-Sebastopol (exclusive) from 27-30 August (inclusive). This includes its stops at Gare du Nord and Gare de l’Est, although other metro lines (including the 5) will still stop there although I haven’t found a central listing of all of the maintenance closures, although https://vianavigo.com/fr/actualites-trafic/ is close.

http://www.ratp.fr/informer/trafic/travaux_ratp.php lists all maintenance works on RER, Metro, and Tram lines.
