Route Transillien H Sncf ( France )

Line H of the Transillian in Île de France + z50000

 

Is this what you are referring to?

 

I like that idea

 

If you want to catch DTG’s attention you need to give a proper description of the line and its rolling stock. In my opinion I don’t think it’s worth it to have the line H as it starts at Gare du Nord which is the busiest station in Europe, knowing DTG it’ll be empty with just the NAT and some TGVs as AI.
