you guys seem to be complicating the transport system too much.

I'm thinking that in each district (or several smaller districts) are 5-6 stations that connect to each other and the Prime station for that district (like Necropolis Prime etc). then that Prime station is connected to 5-6 other Prime stations and an Omega station. that Omega station is connected to all the other Omega stations. that way normal stations are connected to 6-7 stations, Prime stations are connected to 13-15 stations and Omega stations are connected to 6-7 stations. the max travel time is 20 minutes (give or take for missed transitions) and allows people to go anywhere in a short amount of time. (more Omega, Prime and normal stations can be added in if needed but that doesn't affect travel time).

please post what you think about this idea.
