SimCity 4: Rush Hour is an expansion pack for SimCity 4. It includes features, old and new, most of which are transportation related. These include avenues, car and passenger ferrys, and more. Rush Hour also includes a new tool (Route Query) which traces the routes sims take to their destinations, and the type of transportation they use. In addition, several mods for SimCity 4, including the Network Addon Mod (NAM), will only work with Rush Hour. Rush Hour is also included in the Deluxe edition of SimCity 4 and The SimCity Box.
