These two routes connect the Cologne S-Bahn (as seen in the Aachen route) and the wider Rhine-Ruhr S-Bahn, as seen in the Wuppertal and Essen routes. The two lines link the two major cities, along opposite sides of the Rhine, approaching Cologne from opposite directions. The northern terminus of S6 is Essen, but rather than taking the main line route to Duesseldorf, it cuts the corner via Ratingen, joining the main line just south of the airport. To fit with TSW route lengths though, we'll start at Duesseldorf Hbf. For its route to Cologne, it runs in paralell to one of the busiest and most varied main lines in Germany, with IC, ICE and Regional services (of which more later). It also shares tracks with other S-Bahn lines at each end of the route, S1 at the north, and S11 itself further down. S11 comes in from a small branch from Bergisch Gladbach in the west. From Koeln-Muelheim, it joins S6, and runs along the core route of the Cologne S-Bahn, through Deutz (where more routes join), over the Rhine, through the Hauptbahnhof and Hansaring, where it separates from the lines to Aachen, and Koblenz. The line - still shared by both routes, runs alongside the route to Krefeld, a mostly freight route with some regional services. It then branches off to a loop, under the new suburb of Chorweiler. After a few stops on this loop, the line rejoines the main line at Woerringen, where S6 ends. S11 continues along this line to Neuss, a major junction, where it joins the east-west line from Moenchelgladbach. After Neuss, S11 heads west, sharing tracks with S8 and S28, alongside separate tracks used by frequent regional services, which all cross the Rhine again and enter Duesseldorf Hbf from the south. Again, we'll stop here for realism's sake, but S11 continues along the path we described S6 taking earlier, terminating in a branch under the airport. As well as S6 and S11, this route provides playable services on S8, S28, S68 (a peak hour service), RE1 and RE5 along the main line, RE6a and RE7 via Neuss, plus shorter runs on S12, S19, S1 various REs from Wuppertal. There's also 3 or 4 IC and ICE services in each direction between Koeln and Duesseldorf, and short freight runs between Koeln-West and Neuss. Both major stations could see a vast amount of AI. The route could layer in almost all of the German rolling stock already in the TSW catalogue. I'd suggest setting it a few years back - that way x-Wagen, the former S-Bahn coaching stock, could be the newly provided rolling stock, along with maybe an ICE2.
