You might wonder why anyone still talks about a build from 2011. Here is why build 46957 remains a "Golden Spike" for hobbyists:
The Multiplayer Revolution: TS12 was the first in the series to support online multiplayer, allowing engineers to operate the same route simultaneously.

is more than just a software version; it represents the "Gold Master" or baseline release of what many enthusiasts consider the last of the "classic era" Trainz titles.
Searching for a CD key for this specific build usually indicates a desire to return to the simulation's roots before major engine overhauls or to ensure compatibility with older, community-made content. Why Build 46957 Matters
The Baseline Version: Build 46957 is the original Planet Auran release version of TS12. It serves as the mandatory starting point for many manual service packs and patches, such as updating to later, more stable versions like 61388.
Legacy Performance: Some veteran players prefer this earlier build—or the unpatched version—because later updates (like Service Pack 1) introduced performance issues or changed script handling that could break older, "legacy" locomotives and routes.
Multiplayer Milestone: TS12 was the first in the series to introduce a dedicated multiplayer mode, and build 46957 established the initial framework for this feature. Understanding CD Keys and Serial Numbers
In the Trainz ecosystem, there is a distinction between these two terms that often confuses users:
Serial Number: This is the unique code provided via email upon purchase or found on the back of the owner's manual.
CD Key: This refers specifically to the authentication code required for the installer or to register the software with your MyTrainz account.
One-Time Use: A serial number can only be registered once to a single account. If you purchase a second-hand physical copy, the key is likely already "burned" or registered, making it unusable for online features like the Download Station (DLS). How to Acquire a Legitimate Key
