5.18.2016- ESU has been hard at work finalizing their first "Full-Throttle" equipped sound files. ESU has redesigned their sound schedules and function mapping to allow for more prototypical sounds.  The two biggest changes you will notice are the F9 and F10 controls.  No longer are they mapped to prime mover rev-up and prime mover rev-down.

F9 now engages "Drive Lock".  This allows you to lock in your speed and then control just the prime mover sound with the throttle.  You can simulate your train pulling a heavy load up a grade or coasting down the other side (all without changing your speed).  "Drive Lock" also allows you to "pump up your air" and perform brake checks while in the yard.

F10 is now your "Independent Brake".  While moving you can toggle F10 to add braking, or just press it and your locomotive will come to a stop, complete with brake squeal.  Turn F10 off and your locomotive gradually returns to the speed set on your throttle.

Following are the 1st sound files to be released with Full Throttle. Note ESU has also released four brand new prime mover sound files.
