I designed a new metro rail transport concept delivering an improved solution for Sydney commuters and clubbers. http://sydney3000.wordpress.com This network would run 24/7 and get you home safe at night. You won't have to worry how you will get home at 2am even if you live 30km from the Sydney CBD. I also have an additional bus network plan working in conjunction with this metro rail plan but I haven't found the time to document it.
