Everyone has their preferences, and i like to be realistic and for things to be authentic. So twice i have been to Disneyland Paris by train, and so i would love the Eurostar route out of St Pancras to Lille Europe or Paris Nord, and then the TGV from Lille Europe/Flandres to Marne-la-Vallée (Chessy Parcs Disneyland), and maybe beyond to Marseille or wherever else those tgvs go, but id have to be prepared for french driving because i know every place has its respective countryside and all, but it seems France has miles and miles of track.
Amazing idea. We can't forget the Channel Tunnel. What about the Le Shuttle freights that run through the Channel Tunnel?
As much as this would be a great route (and I think a very popular addon given it's been suggested many times before for both TSW and TS19), Eurostar are quite awkward with their licencing and have refused a licenced addon before for the Eurotunnel, so any official addon is probably not going to happen soon. That's not to say someone won't try to make the route for TSW/TS19, in fact I think there is a Eurotunnel route in progress for TS19 (search on Facebook for "Atlantic HIGH SPEED") so it's not out of the question once the tools become available.
It would be cool man, the cab controls look a lil complex but would be fun to learn, ive seen someone drive the javelin and i love the fact that yoi can change something in the cab that effects the mph, its got this bi mode thingy, i think Eurostar have it to for when they get outside of the UK.
