The Mac version of SimCity 4 Rush Hour is expected to ship in September.

Players take control of a city’s transportation system. Possible solutions include creating elevated train networks and developing a mass-transit systems including monorail, subway, or ferry services.

Whether success in the game qualifies players to sort out London's transport nightmares remains to be seen. Perhaps Mayor Ken Livingston will be getting a copy.

The game requires SimCity 4 to play. It runs in Mac OS X 10.2.3, needs a processor speed 500 MHz or faster, 256 MB RAM, 1 GB of free hard disk space, and an ATI Radeon or NVidia GeForce card.

The game can be preordered at Aspyr. It will cost $30.
