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.

The Network Addon Mod (NAM) combines all transportation network-related fixes, additions and new creations that have been released so far. It will add countless new features to the existing network tools, such as new overpasses, highway onramps, intersections, ped-malls, a ground light rail network, roundabouts and turning lanes. This is the standard release version of the 32nd edition of the NAM, NAM 32.

To install the NAM 32 Pre-Release, run the Self-Extractor file (NetworkAddonMod Setup 32 Pre-Release SFX.exe) to extract the installer, then find the installer (NetworkAddonMod Setup 32 Pre-Release.exe) and run it to install the NAM.

The official support forum for NAM 32 is located at SimCity 4 Devotion, the home of the NAM Team.  You can find it here.

NAM Version 32 requires a retail disc or digital download copy of SimCity 4 Deluxe, updated to at least 1.1.638 (the version number for disc copies, with the EP1 patch applied--most retail digital download copies are pre-patched to Version 1.1.641).

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.

  • 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.
  • 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.
  • Note: If you downloaded the full release of NAM 32 during the brief time it was available before 12:30am US Pacific Standard Time (UTC-8:00) on 1/15, you will need to redownload it.  An outdated controller build made it into the build, which has since been corrected.

I need help. I am new to this and never modded anything before. my regular roads do not look like nwm. Do I have to download that separately somewhere? please help a newbie. I got SC4 rush hour from steam not too long ago and this was the first thing I added to it, no other plugins or anything was there before this. thank you for your time.

NAM does not replace your roads, it adds roads. Look in the menu for the additions. Make sure you install NAM to your plugins folder. For example C:\Users\YOUR-USERNAME\Documents\SimCity 4\Plugins.

Hi Everyone. Thanks for all your hard work. The achievements of the NAM team are nothing short of astounding. I've been engrossed in SC4 both as a user and developer for 2+ years now. After scouring all the NAM32 docs and forums, I'm stumped by what is almost certainly a simple notion. When in the "Choose Components" screen of a custom installation, what does the bold face prefix *NR* or *SR* refer to when checking a box such as RHW or NWM? Thank-you in advance for the insight.

*NR* means "No RULs" and *SR* means "Some RULs", if I'm not mistaken. It ties in with the RUL decoupling option (which allows existing instances of some networks to continue to exist in cities, but doesn't load their RULs, cutting down the size of the NAM controller).

Please, can someone tell me how I can install this add-on on my Mac?

Not easily. Unfortunately, we are not presently supporting the Mac version, due to the fact that the present release (and all previous ones) cause CTDs with the new re-release.

First, I'm a huge fan of this mod! But I'm having a few problems with the installer.

I have my region saved in a dropbox folder, but when I've tried to install this version it doesn't install the files where I tell it to. It looks like it's installing the mod in the "My Documents/Sim City 4" folder still.

The other problem is it won't let me change the install path. I've no idea why this is a feature with setup programs lately, but I'd like to try to install to the default folder then move the plugin files to the dropbox folder.

What I'd like to do is install everything but those single piece tiles as I'm not patient enough to mess with putting in one piece at a time, and I don't like how they fill up the menus.

I ended up copying the files from the plugins in "my documents" over to the files in the dropbox folder and it's working. But thought I'd point out the problem I had with the setup program not installing where I told it to.

I like the changes in this latest version so far!

Our HSR developer did recently return from a long hiatus, so the project will actually be getting a bit of attention for NAM 33. I don't know what entirely will be developed, but stay tuned.

In theory, yes, but if you're using the recently re-released Aspyr port, you're going to encounter some issues with certain files. We are very close to having a proper Mac version again, however, which will have an installer for the first time.

There should be a big red "DOWNLOAD NOW!" button near the top of the page. You don't need to be registered to see it.

That's probably the most asked question in the past couple months. We are getting quite close to having a version compatible with the Mac AppStore/Steam version, which will be known as NAM 32.1. However, we can't give any specific date or timeline for when it'll be released, other than a vague "very soon".
