Welcome to Day 3 or our 15th Anniversary Celebrations.

In late 2003 with the release of TRS2004, the were enormous changes to the variety of things you could do with Trainz.

Interactive industries, commodities, waybills, steam engines with cab controls, placing consists in the 3D world rather than in pre-defined positions, and unlimited Saved Driver Sessions were but a short part of the long list of additional functionality.

As we reached 2003, as a sign of the increasing depth, breadth and complexity of Trainz, TRS2004 came complete with not one, not two, but seven manuals!

Here is the list of manuals found in C:\Program Files (x86)\Auran\TRS2004\Docs\manuals_cd

  • Content Creators Guide
  • Engineers Handbook
  • Expanded Manual
  • Signalling Guide
  • Technical Manual
  • User Activity Creation Guide
  • World Builders Guide

Chapter 2 of the Technical Guide included this fantastic "What's New?" section:

If you have enjoyed previous versions of the Trainz product, we’d like to bring you up to date with a list of the major new features you will find in TRS2004.
• You can now allocate Drivers to each locomotive
• Drivers can be given orders to carry out tasks
• Interactive industries demand and supply goods
• Work orders or ‘Waybills’ are automatically created by the new interactive industries
• Steam engines including 3D cab controls based upon real world physics data
• Consists are now placed in the 3D world of Surveyor
• You can name and save your consists for rapid placement on new routes or layouts
• Trains/Consist selection can be filtered in Surveyor using “Favorites”
• Support introduced for animated unloading/loading of goods and resources
• You can now create multiple Sessions for one route with different consists, starting points, industry outputs etc
• Unlimited number of Saved Driver Sessions
• New GUI to apply scripted “Rules” to objects, trains or drivers
• Signaling has been improved and now supports animated semaphores
• You can use a new free-roaming camera view to navigate around your world
• Improved graphics cards support
• New graphics engine (Auran Jet V2.0) adds features such as bump mapping, specular highlights and vertex shaders
• Variable water model including wave height, color and reflections
• Tons of new content and useful 3rd Party Utilities

Back in 2004, Driver Sessions were called "Activities" or "Scenarios". Users could for the first time create the own scripts using the "Trainzscript" language developed specifically for Trainz.


TRS2004 also saw a new Intro Movie paying homage to Auran Jet (engine technology) and Auran (publisher of Trainz at the time).

The movie reflects the focus of Auran at the time on more than just the Trainz franchise. Unfortunately these little critters never saw the "big screen" as they were intended. Ah, the joys of being a game developer...


"SP1" was a major enhancement to TRS2004 and introduced, among other things, significant upgrade to the steam loco physics simulation.

Service Pack 2 - Passenger Pack

Until this point, TRS2004 had focused on interactive indutries but not passenger stations. A little known, possibly never-before-mentioned reason for this was that we were working on animated passengers and it was taking longer than expected. In the end, we opted for fade-in/fade-out passenger loading. Maybe one day we'll get animated loading...

Service Pack 3 - August 2004

This pack featured further optimization for smoother game performance, bug fixes, enhanced train detail, and more.

Service Pack 4 - January 2005

The final update for TRS2004 was SP4 which delivered even more performance enhancements and bug fixes.
