As my main language is not English I apologise in advance for any error I might have commited while writting this. Feel free to correct me. The HSL 3 is a Belgian high-speed rail line. It connects Liège to the German border near Aachen. The high-speed track length is 42 km (26 mi). Route: Trains leave Liège-Guillemins station over the upgraded classic line (Belgian railway line 37), at speeds which progressively rise to 120 km/h (75 mph). The dedicated high-speed tracks branch off from the "slow" line (Belgian railway line 37) at the bridge over the Ourthe, between Angleur and Chênée stations in the suburbs of Liège. The line crosses the Vesdre river, then traverses the 6.5 km (4.0 mi) long Soumagne Tunnel between Vaux-sous-Chèvremont and Soumagne. This is the longest double-track tunnel in Belgium, and has a speed limit of 200 km/h (124 mph). The line then runs parallel to the A3 motorway with a speed limit of 260 km (160 mi) shortly after the village of Walhorn, it passes under the A3 in a cut-and-cover section, and rejoins the regular line (Belgian railway line 37). Trains run on the upgraded classic line 37 at 140 km/h (87 mph), pass over the Hammerbrücke viaduct , and cross the border 2 km further on. Beyond the border, high-speed trains travel along upgraded existing rail lines to Aachen Hauptbahnhof. Trains use left-hand running along this section (as in Belgium), switching over to right-hand running, which is common in Germany, at Aachen Hauptbahnhof. Route Map: Rolling Stock: HSL 3 is used only by international Thalys and ICE trains. The same ICE 3M we allready have in the Schnellfahrstrecke Köln - Aachen route is used in this route. As for Thalys trains it depends on the licenses DTG have. Why this route: 1. As this route can be connected to the Schnellfahrstrecke Köln - Aachen route, ICE services can be extended up to 1h of travel time which will give a greater gamplay experience as the actual services can sometimes feel too short. 2. This route will add another country to the TSW2 library which is something many players have been requesting troughout the years. 3. This route uses the European Train Control System (ETCS) which will bring new gamplay opportunities as well as new challenges for the players. 4. As it is not a very long route and it's mostly high speed line the only stations that are present appart from Liège-Guillemins station are Hergenrath, Chêneé and Gare d' Angleur which should make the route easier to make. Please comment your thoughts on this route. Thanks for taking time to read this, have a great day =).
