I have a trigger that creates a conductor and moves the workcart fwd at hi speed.  I created a spawn point with several wagons, but when the train comes back around, it stops for 30 seconds at that spawn point.  Is there a way to remove the 30 second stop so that the train just continues on?  Or is there a way to spawn the train with workcarts on the "Conductor Fwd Hi" trigger?

Yes, the brake and stopping feature are optional, and any trigger can function as a Spawn Trigger.

You can add a spawn/conductor trigger with something like "awt.add Spawn Conductor Fwd Hi Default" and it should not function as a stop. You can update your existing trigger to do this by changing that command from "awt.add" to "awt.replace" (with the same parameters, while aiming at the trigger), then add back your wagons.

If you already have a "Conductor Fwd Hi" trigger, you can run "awt.update Spawn" to make it also spawn a workcart.
