Hi, I propose to add the Bordeaux-Arcachon line to TSW. It is a 200 years line, 60km from Bordeaux Saint Jean to Arcachon. The line is very used in summer but there are many trains the rest of the year. There are: TGVs: TER( regional trains) with regio2n and regiolis and some b81500 sometimes there are freight traffic for Cazaux Airbase. The line deserve Bordeaux, Pessac, Cestas, Marcheprime, Biganos, Le Teich, Gujan-Mestras, La teste de Buch and Arcachon. The journey takes an hour.
This route should be made and one of these trains the Euroduplex can run on this route and Hauptstrecke München-Augsburg as a Paris Est Strasbourg Augsburg München Hbf service. Reason it has 15kv AC active. TGV R run on this route and LGV Méditerranée.
