You're supposed to introduce the route to those who don't know it here. Tell us about it, it's length, stations and stock used.
So... this is what I could find from the web. I have no clue if this is what OP is talking about. Then we have the trains. Quick excerpt from the Wikipedia about the trains: Vehicles from the MS 61 , MI84 , MI 2N and MI 09 series are used on the RER A. The MI09 series trains gradually replaced the MI 84 trains. At the beginning of 2014, 60 new trains were in use. In mid-January 2015, 83 MI09 trains and 43 MI2N trains were running on the RER A routes. At this point it was decided to order 10 additional units of MI09. After delivery of all ordered trains by 2017, 140 MI09 trains and 43 MI2N trains should be used. So, this is all fine and dandy, pretty solid looking route and all but can you explain why this should be in TSW?
I want so much the RER on TSW. For the RER A, I think the route would be very good if there are also the old rolling stocks (MS61 and MI84) with the current rolling stocks in the route. Or also make the line L drivable from Nanterre Université and between Houilles and Cergy Le Haut.
