What is the UDS Interface?
 |
The UDS provides a means of quickly switching from Driver mode to Surveyor mode and back to Driver again without having to restart a running session after each switch. It is only available in TRS19 Platinum Edition and Trainz Plus |
UDS stands for Universal Driver Surveyor and is an "interface' or option built into TRS19 Platinum Edition and Trainz Plus that allows you to jump seamlessly from Driver into Surveyor and then back into Driver again to resume a session at the point where you left it. There is no need to restart a Driver session from the very beginning.
| The Scenario: You are in Driver mode testing out a route and session when you discover a problem. |
 | Previously (before UDS) your only options would be to:-
In both cases you would have to:-
|
The UDS interface allows you to halt the Driver session (press the P key) and then switch, via a menu option, to Surveyor without having to stop and exit Driver mode first.
| The Scenario (continued): Using UDS you switch from Driver to Surveyor with the currently active Driver consist still as the focus and at the place it was located when you switched into Surveyor from Driver. |
 | All the Surveyor tools and options are available for you to use, including the Session Editor (more on that later). | |
 | You use the Surveyor tools to fix the problem, such as deleting, moving or adding a scenery object (as shown left). You can then (if you wish) save the edited route and/or session (again there will be more on that later). |
|
 | You then switch back into Driver to continue driving the session with the problem fixed. |

Most of the problems users seem to be experiencing with the UDS, judging from the posts in the Trainz Forums, is when saving their edited Driver session after switching to Surveyor mode.
|
Using Driver Mode involves driving consists (either manually or through the AI) and activating rules. These will change the session parameters |
When you are in Driver Mode at least one of the consists will probably be moving. Some of the Session rules may have already been completed while others may still be running or waiting for events (e.g. triggers to be activated). If you then choose to save using the Overwrite the existing session option then you will be replacing your original starting Session with the changed Session in its current condition. The consists will be saved in their new positions, the Session rules will saved in their new states. So when you later load and start the Session, some of the consists may not be in their original starting positions and some of the rules may not be in their original starting states.
 |
In TRS19 Platinum Edition and in Trainz Plus it is recommended that all consists should be placed into a Session Layer and become part of a Session instead of the Route |
