If am mistaken within the roadmap stream there was a discussion involving the amount of detail that goes into creating a train , developing the interior where passengers sit and suggesting that people don't appreciate it alot. As mainly players sit in the driver's seat. I for one is concerned with this as detailing in these locos could be decreased and perhaps could turn into TS where you only have access to the cab. I think it's incredible to see the whole train. Being able to walk through each carriage , sit at any seat regardless of train operator. There is a lot of detail to be seen. For the price we pay for train addons the amount of detail is perfect. Some possible key problems - Scenarios need to have variety. so for this rush hour service good one could be you have to catch a connecting train into Brighton to start another service to London victoria. Start the user catching a service or something. - when siting as a passenger seat the audio is dreadful to listen to and can be very off putting. Routes aren't that busy even when spawning in the morning And it gets said a lot but multiplayer would also help to fix your concern as players would sit in carriages with their friends. Modes developed such as ticket inspector/train conductor could help get people to get in the carriages more. The rush hour routes could sway more people to spawn as a passenger more as the routes should be more busy.
