So as I understand it some of the timetables in the game are created through AI generation through which an AI starts at a set time time and the subsequent timings for stops along the route are created based on the AI's run of the route. The alternative to AI generation is I assume manual timing entry, based on real life timetables which I assume to be a much lengthier process. Now, assuming my understanding is correct there are a few issues with AI generation but I am going to focus on one for now as something of a thought experiment. Now as timetable mode is one of the core advances made by TSW over TS this is a much greater issue for TSW over TS and has wide reaching consequences. For example, the use of AI timetables inhibits the ability to make alterations to the physics of the trains. If the acceleration or braking of a train is inaccurate then correcting it renders the AI generated timetable redundant as the timings can become an impossibility. It would seem that improving the accuracy of just one train with timetables on multiple routes potentially being affected. The consequences of this go further too, surely it is harder to notice when a loco's performance is not quite right if it is running a timetable set by the performance of itself rather than a real timetable. Similarly if correcting the physics of a locomotive can effectively break the timetable(s) then the timetables would have to be remade to fit the new physics of the locomotive then the workload becomes massively increased and potentially unviable. The result is that the physics of the train may not be able to be altered to better relfect the real train. With a simulator people desire the closest reflection of reality possible and we are certainly all aware of just how passionate people are in achieving that. It seems to me, that AI generated timetables not only often fail to match reality but can result in being stuck with a train with physics that aren't up to scratch, the consequences of which can impact other aspects such as sound. In all, my understanding may not be entirely correct and I am almost certainly thinking of the worst case scenario in terms of the consequences of this, though in my mind 'prepare for the worst, hope for the best' is usually the best course of action. From this I would like to ask a few questions: First, is my understanding of how AI generated timetables are created correct and if not, how it does? Secondly I would like to know which routes rely on AI generation to create the bulk of its timetable, mostly out of curiosity. Also, I would like to know if this process is still being used. Finally, I would like to understand the benefits and limitations of AI generation in order to further my understanding and open a discussion into the attitudes of timetable development in TSW as a whole.
