Hey there, I want to purpose you to make the RER A line! It's a pretty huge network with differents branch (5 branch and 1 central branch who connect all). It's the most used line in Europe (1 million users per days). It's exploted by the RATP (Régie autonome des transport parisiens) and the SNCF (société nationale des chemins de fers français). They use 2 types of trains : the MI2N (old one) and the MI09 (most recent). I sincerly hope to see this line in TSW one day! Have a great day, Sopaa
