I honestly don't see the hype in merging 2 routes if trains in real life don't even run between those 2 routes. Rhein Ruhr Osten and Ruhr Sieg Nord Let's take Rhein Ruhr Osten and Ruhr Sieg Nord for example. Yes. They do connect with each other. But what most people don't understand is that none of the passenger trains run along both routes. RRO sees RB48, RE4, and RE7 regional trains. Then you have the S9, S8, and S5 (depot only) for commuter trains. Meanwhile, RSN only sees RE16 and RB91 passenger trains. As you can see, none of the passenger services intertwine with each other. RB48 doesn't even go to Hagen, RE4 goes north towards Dortmund, and the RE7 goes up to Rheine. The S9 line doesn't go to Hagen, the S8 terminates at Hagen, and the S5 goes up to Dortmund. Meanwhile, on RSN, the RE16 goes up to Essen Hbf when it reaches Hagen, and the RB91 terminates at Hagen. Literally, the only thing that could possibly be intertwined is the freight services. However, the rolling stock used on them are completely different. Now it's possible that some of the freight services from RRO do go onto RSN, but a new timetable would probably have to be put in place to even consider doing that. Overall, it's just completely pointless. Dresden-Chemnitz and Riesa-Dresden Already there is a major problem. The routes are set in 2 different time periods. Riesa-Dresden is set to around modern-day or pre-covid, while Dresden-Chemnitz is set in 2013 (Correct me if I'm wrong) due to the 143 being replaced by the DB BR 1440. This means that the scenery isn't 100% exact in Dresden. Secondly, the night lighting is different on both routes, meaning DTG would have to spend lots of time adjusting the night lighting so that they do not contrast each other. Thirdly, none of the services intertwine since Dresden has terminating platforms. All you would be able to do is walk to trains that run on the other routes. Brighton Mainline and East Coastway This is probably the most requested route merge. However, most people do not realize that trains on East Coastway do not run onto the Brighton Mainline via Brighton and vice versa. If DTG really wanted to connect these routes, they would have to include the 10-mile branch line that connects Lewes to Burgess Hill. This is the only route trains take if they travel between East Coastway and Brighton Mainline. East Coastway trains do not terminate at Brighton and then head down to London and vice versa. Trains take this branch line since it reduces travel times. This makes connecting the 2 routes almost pointless unless they add the connection at Lewes. But then at that point, it's more of an extension than a route merge. Just like with the Dresden routes, all you would be able to do is walk from ECW trains and BML trains. Great Western Express and Bakerloo Line I honestly don't see the point in connecting these two routes. All it would benefit are people who want to roleplay as passengers. Obviously, no services intertwine with another. Extensions that could allow routes to be connected Many people have wanted to see extensions that would again allow route merging. The most obvious one is extending Southeastern Highspeed to London Victoria. Although many people think this would be cool, if SEHS is connected with BML, it then connects with ECW which would mean hundreds of miles of track are merged together into one route. I highly bet that merging 2 50 miles routes, and a 30 miles route could lead to some major technical issues. Another one I see a lot is extending Haupstrecke Rhein Ruhr and Rhein Ruhr Osten together. Again, this would accomplish almost nothing. The only extension that remotely makes sense is extending the S9 line to Essen Hbf. Although this makes S9 services longer, it still diminishes the point of merging the routes since it then only makes one extra stop after Essen, until breaking off from HRR. Honestly, all I see this appealing to are people who want to roleplay as passengers or people who want to drive a service from one route and then walk to another train to play a service on another route. There are other things that DTG should be doing before even considering merging routes. I feel like the technical hurdles that this could have would make it not worth it. Now one possible solution is if you were to for say get off of a train from ECW and want to go onto BML, it would despawn you from ECW and put you onto BML. However, if this was to work, the timetables would have to be 100% corresponding to each other. This most likely means that Joe would have to update the timetable on East Coastway to match the timings on Brighton Mainline's timetable. Something like this I think could work and seems a lot more simple than just merging multiple routes together. Now I am all in for extensions of routes, I don't want anyone to think I'm against extensions, but DTG needs to have an actual reason to merge a route instead of doing it just because they connect to each other. Matt also made a lot of good points on the May 3rd roadmap stream about the technical challenges of merging routes. I think he explained it the best way possible. I would much prefer DTG to focus on extensions for routes that badly need them, than merging 2 routes that don't really need an extension. If anything, DTG should be working on new routes as TSW still has a major lack in variety. Germany for the most part is getting there, but the US and UK are still missing various popular trains and locations that should be done. There are also many countries that I would love to see get added to the game. That is what DTG should be spending their development time on other than fixing the game. They need to get the game's variety up to TS's standards. Route merges are just an unnecessary addition with very few benefits compared to an extension or new route in general.
