Paris Métro Line 13

Hello everyone ! Today i'll suggest a new route for TSW2 which comes from Paris in France. Paris Métro Line 13 ( French : Ligne 13 du métro parisien).
It's one of the most frequented subway in the world on one of the biggest railway ( Paris ). The line lengh is 24.3km (15.1 mi) actually and opened 26 February 1911.

Paris Métro's owner is RATP (French : Régie Autonome des Transports Parisiens). It would be great to have another french route and subway on TSW.
With this route, you can pass below Paris and go until its surburb.

Rolling Stock : MF 77 (actually)

 

Speak english pls.

 

How much of this route is underground?

 

The Line is overground from Châtillon Montrouge to Malakoff - Rue Etienne Dolet and between Mairie de Clichy - Gabriel Péri.
Not so amazing.

 

I have the same Idea of suggestion thank you for this suggestion
