There's no way to view this in-game and it's unlikely to be added back in again. Information is definitely outdated and you shouldn't really take it to heart.
- The Leighton Zone was designated in Leighton which in reality would look like a small city.
- If you travel to Rocket Parade you will be able to see BanTech Systems Headquarters from Platform 2.
- Strangely, Leighton City is not connected with the other stations via road, making it rather quiet and isolated from the rest of the zone. It is possible to get there by foot, as there is nothing able to despawn the player.
- In V1.7 this is now in the Signalling Zone D.
