Hello everyone ! This route is a combinations of lines in France Belgium and Germany. The LGV Nord that goes from Gonesse to the border between France and Belgium. The LGV 1 From the border between France and Belgium to Hal. The LGV 2 That goes from Leuven to Liège in Belgium. The LGV 3 That goes from Liège to the border between Belgium and Germany. The LGV Interconnexion from Gonesse to Marne la Vallée Chessy; +The LN36 Between Brussels and Leuven. +The LN96 Between Hal and Brussels. +The Paris-Lille line from Paris Nord to Gonesse. +Branch to Arras +Branch to Lille Europe The Total of the route is aprox 440km You may think that high speed on TSW is boring and always the same. It's true for most of the part because the route are linear and there's only one service to do (SKW,LGV). But everybody (I think) like the Javelin because of the diversity of services it offer. (Saint-Pancras -> Ashford or Faversham) That's why for me a good high speed route should offer high speed (Obviously) and variety. And here's why the corridor from Paris to Aachen is a good idea. Let me explain There is first the Thalys services with the Thalys PBA and PBKA. These services goes from Paris to Brussels and then stop at Liège and Aachen. The Thalys PBA can not goes to Germany so it will stay at Brussels. +Thalys offer services to Disneyland Paris from Brussels and Köln Then there is the Eurostar services from Lille Europe to Paris or Brussels. These services are done with the Class 373 or the Class 374. + With these there is a possibility to layer it on SEHS. Eurostar also provide London-Disneyland services Between Brussels and Paris the SNCF(Société Nationale des Chemins de fer Français) operate services with their TGV Réseau. On the LGV Nord there's also TGV Duplex operating and some with the Ouigo livery(Ouigo is a lowcost branch of the SNCF). And what is nice with the TGV is that if you have a TGV Réseau and the loco of a TGV Duplex you have a TGV Pos(With minor change to the cab). The SNCF also provides services to Marne La Vallée Chessy and the Charles de Gaulle Airport with their stations. On the LGV Nord there is also a small branch to Arras where TGV do services to and from Paris Nord. And the "pass trough" station TGV Haute Picardie where some services stop. Now between Brussels and Liège the SNCB (Société Nationale des Chemins de fer Belge) provide Inter-city services on the LGV 2. (These services can go up to 200km/h). They are mostly operated by HLE 18 locomotive with double level M6 coaches. The HLE 18 is a vectron without the mustache (DTG you know what to do with you Vectron) Theses services stop at Brussels -Midi,-Central,-Nord Leuven and Liège. Now since the LGV 1 and 2 don't go straight in Brussels the TGV take normal lines. These line are quite short but are part of the S-Bahn Brussels web. The S Services are operated by Desiro EMU "AM 08". These EMU can go up to 160km/h. I include them in my sugestion because the track are "already there" Now a layer from SKA is possible. The ICE 3 (DB BR 406) can layer for additional services between Aachen and Brussels. The ICE 16 is already playable between Köln and Aachen. These services stop at Aachen Liège and Brussels. I think that's all (Yes I dream a lot) Paris Gare du Nord:- Charles de Gaulle TGV with a TGV Réseau : Marne la Vallée Chessy TGV (Disneyland) with a TGV Résau: TGV Haute Picardie with a Thalys PBKA: Lille-Europe: Gare d'Arras with a TGV POS: Brussels Midi with a Thalys PBKA and a ICE 3: Brussels Central: Brussels-North with an ICE 3 passage: Leuven Station: Liège-Guillemins: M6 Double level coaches with a cab car: HLE 18 Locomotive: AM 08 EMU: Eurostar E300: Eurostar E320(Which is the same train as the ICE3 Neo): Thalys PBA (Paris-Bruxelles-Amsterdam): Little map: Zoom on Brussels: What do you think ?
