This is a Work In Progress
The information in this Wiki Page applies to TRS19 Platinum Edition and Trainz Plus. T:ANE and TRS19 (standard) do not have the UDS feature described in this document.

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:-

ignore the problem (if possible) to continue the session in Driver and fix the problem later, or
immediately halt the session to fix it now

In both cases you would have to:-

load the route into Surveyor and try to recall exactly where the problem is located
fix the problem
restart the session in Driver from the beginning (a bit tough if you were 2 hrs or more into a 3 hr session)

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.
