The TSW2020 interface does not link to any instruction manuals, which are needed to get the most out of TSW2020. Manuals are mentioned (for example, in the NTP "Diesel Locomotives Introduction" module), but are not actually available in the game. TSW2020 is a fairly deep train simulator, with some complex functions modelled (signalling and safety systems, etc.), but the average PS4 player needs (and/or expects) everything to be explained from the very basics of railway operation and increasingly complex locomotive controls, to how the features in the UI and scoring system work. Train simulators have been around in the consumer market for about 35 years. The 1985 ZX Spectrum game "Southern Belle" was playable, and easy enough to understand by ten year olds. But modern simulators are complex, and if you get stuck and there's no manual, most people will give up. There is no current manual available for TSW2020, for the PS4, at all. Even Southern Belle had a manual, with the software. There is a new manual for TSW2020 for PC, and old manuals designed to include reference to PS4 for the original TSW(2018). Even these ill-fitting manuals can't be easily accessed. An updated manual (for PS4) needs to be available from within the game - if a live online DLC shopping section can be included in the UI, then a section with some instructions on how to use the software should be fairly easy to implement - it would help keep players "on board".
