Airport West was in the Airport Zone, but it was not mentioned on the map.
Strangely, the AirLink Headquarters is not within the Airport Zone even though AirLink is the dominant railway operator for Stepford Airport. Instead, it is located in Berrily, which ironically was the least served station on AirLink.
Some argued that James Street should have been in this zone due to its proximity to Airport West, although the pre-V1.6 map did not mention it.
During the Developer Q&A on 23 October 2021, Managing Director Charlie_RBX confirmed that this zone will receive a huge overhaul in the future. The reason is that the stations have never received a major update for a long time, plus the height of tunnels in this zone are too low to accommodate the overhead line equipment and pantograph of trains, which is planned to become functional in future.
Note: All information below were pre-V1.6, before zones are removed.
