The Network Addon Mod, or NAM, is a modification for SimCity 4 Deluxe (or SimCity 4 with the Rush Hour Expansion pack), which adds a myriad of new transport network items, ranging from ground light rail, to fractional-angle roads, to roundabouts, and much more. It also includes bugfixes to Maxis items and a highly optimized set of traffic simulator plugins, improving pathfinding accuracy and performance.

New features in Version 32--January 14, 2014

NAM 32 is a full package, which improves upon the earlier NAM 31.2 release and NAM 32 Pre-Release.  Note that the NAM requires a retail copy (disc or digital) of SimCity 4 Deluxe to run.

  • The NAM Elevated Viaducts for Roads, One-Way Roads, and Avenues are now available in a draggable form, at both Level 1 (7.5 meter) and Level 2 (15 meter) heights, complete with FLEX Height and On-Slope transitions.  Overpass situations involving one or more diagonal networks are not yet supported, and will not be available until a future NAM release after Version 32.
  • Elevated Rail-over-Avenue and Elevated Rail-over-NWM Road-4 dual-networking support has been added, complete with a new station supporting both networks.
  • The initial phases of the RealRailway (RRW) system have been added.  This feature must be selected as part of a custom install.
  • The RealHighway (RHW) system has been expanded to include the QuickChange interchange system, which blends the RHW's modularity with the ease of Maxis Highway construction techniques for certain situations, which will be expanded in future NAM releases.  Additionally, several new types of FLEXRamps are available--please read the instructions in the description text.  FLEX Transitions have also been given stability improvements for certain situations.
  • Coupled with the RHW system, the NAM now offers Bus Rapid Transit (BRT) functionality, including stations.
  • Transit station functionality has been further improved, including the beginning of the implementation of the SLURP, which will gradually raise all transit stations to NAM standards.
  • The NAM Controller Compiler has been included with the installer, with which it now communicates, ensuring that only the installed features are incorporated into the NAM Controller, reducing file size and load times.
  • About 50 bugs reported since the start of the NAM 32 Pre-Release have also been squished, including some that had been present since earlier versions of the NAM.  It is highly recommended that users update to the latest NAM in order to enjoy a more stable experience.
Network Addon Mod - Version 32

Installing over previous versions: NAM 32 may be installed directly over top of any previous NAM releases. It is a full release, not a patch or a hotfix. All
future updates are planned to be in full package form, and there are no plans to issue patches or hotfixes in the future. Please also note that the NAM Team only provides
technical support for the most recent version, which, as of this document, is NAM 32. We cannot assist users of the NAM 32 Pre-Release, NAM 31.x-series release, or earlier.

Special Thanks: The NAM Team would like to extend its sincere thanks to all the members of the community who helped test the NAM 32 Pre-Release, offering feedback and helping us locate and solve bugs.

Stupid question - is starting a new game required to make NAM work correctly or can I simply continue playing with my vanilla cities safely?

You can use NAM items in any city/region you have, including ones built before you picked up the NAM.

Thanks for answer. I really wanted to try playing with NAM but wasn't sure what will happen with my cities after I install it.

NAM dev team - Now that SimCity 4 has been completely re-written for OS X can you guys make the NAM work with it? Thank you!

Our lone Mac user on the team has picked up the new edition of the port (he had been previously running the Windows version on a dual-boot), and by and large, it appears it hasn't been "completely re-written". The same issues that previously existed with the Mac port with the old Universal Binary patch still exist with the newly released version.

Now that the Mac port has been revived, and we have a better chance of diagnosing the issues, we have re-opened the issue, but due to the inexplicable nature of the problems, we can't make any promises at this point.

If you're running the Windows version, either on a dual boot (e.g. Boot Camp) or using WINE/Wineskin, yes. But if you're running the Mac port by Aspyr, there's no support for that. Certain critical files in the NAM will actually cause the Mac port to crash if you're running OS X 10.7 or later.

Apparently, we managed to miss the fact that NAM 32 made PC Gamer's "Mod of the Week" last month.
