Won't someone think of the Ai overlords who will take care of all this for us in the future. A bit of consistency goes a long way.

One of the best game I ever played is the text based souvenir game shopping game on Windows 3. I can't recall the name of the game now since it's more than 30 years ago, but it's about shopping souvenirs using London Underground Tube. You have a semi realistic time constraints like train schedules, your flight schedules and of course list of souvenirs items to shop. This is totally offline since there is no Internet available at the time but it's very engaging nonetheless.

My proposal for the modern version of the game is to use real-time train schedules (with delays, ticket discounts, etc) that are available publicly on the Internet for many metropolitan cities in the world for examples Tokyo, London and Berlin.

Imagine you can have a real-world realistic in-app in-game items purchases feature that you personally can buy in the game and delivered to you or anyone you fancy of giving souvenirs except that you only virtually went there.

It doesn't, at least not for most lines. TfL's data is notoriously inconsistent, with multiple backends used for different purposes. For most lines, the dot matrix indicators are fed by the signalling system and timetables (more modern signaling systems are timetable-aware). Meanwhile, the online API relies on estimates from TfL's TrackerNet.
