In the "End of year Q&A" Matt said many people don't think TSW is a proper simulation. He would be interested in a discussion about this, which I would like to open. Very briefly about my background (and why I'm so interested in this topic): So I'm that hardcore simulation guy. I've built an Airbus A320 home cockpit, where almost every switch works, based on X-Plane and the FF A320 - so I think I have a pretty accurate idea of "simulating" stuff. Unfortunately, I can only speak for german trains. If you want a benchmark for german train simulation, you can't get around Zusi, together with ZusiDisplay. In the comparison to TSW, it is particularly noticeable that with Zusi the German signalling system is implemented in epic depth and complexity - TSW is very "simplified" and "generalised" in this aspect the train safety systems with their versions and variants and special features are implemented even more accurately (to get a feeling: there are Indusi I54, I60, I60M, I60R, PZB60 (ÖBB), PZB90 1.5 / 2.0 as well as door security systems, LZB etc...) (partly because of ZusiDisplay), the displays in the locomotives (and the underlying technical systems!) are very realistically implemented. This starts with the start-up of the locomotive and the accurate input of the train data and it ends with special displays such as EBuLa (basically an electronic route plan). german track construction (catenaries, switches etc) are implemented extremely accurately Other simulation aspects are e.g. radio communication with the dispatcher, simulation of system failures on the train or simulated technical problems on the track, more control over weather conditions and again... many specialities on individual locomotives. As an example here the DB BR143 with its special driving programmes ("bedingter Auslauf", "nur bremsen", "nur fahren" etc.). These are typical features of the BR143 that are largely missing in TSW. But now comes the crux of the matter. If you want to implement a locomotive so realistically, it would be just as much of an effort as, for example, a highly realistic aircraft add-on for MSFS / X-Plane, etc. Let's just see how long PMDG needs to develop an aircraft addon and how expensive(!) the final product is! That is completely impossible for DTG alone. This can only be done by third-party developers, who would need years of experience(!!) on this platform (and years of development). In addition, such highly realistic trains / locomotives would be absolute niche products - I'm not sure if something like that would sell well enough. Which brings me to the last point... do we need such an extensive "simulation"? I think TSW is going a different way here and that's fine. It's not about simulating locomotives/trains down to the very last nut and bolt and computer chip, it's about getting the feel of what it's like to drive a particular train on a particular track. TSW gives a very good impression of what a PZB / LZB feels like, how different signalling systems basically work and what makes up the railway in different countries. In my opinion, TSW manages the balancing act between simulation and entertainment almost optimal, and you learn something about the countries, the railway traffic there and about technical specialities. For me, it is a wonderful, educational and entertaining game with simulation aspects. I love it as it is. In some ways TSW even can be much more than a mere simulation: it looks nice, creates immersion and allows other activities than train driving. For the German routes, I really only miss EBuLa and maybe a little more functionality in the MFDs. More simulation depth is not really necessary in my view, but more bug fixing(!!!) and a more stable and mature platform overall. Things like a simplified communication with the dispatcher would be a nice-to-have. The best thing would certainly be to develop a kind of open interface (SDK), to which other developers could "dock" with things like ZusiDisplay or passenger announcement systems. TSW is unfortunately still too restricted at the moment.
