GE Evolution 12cyl "GEVO" Locomotives have a 4 stoke diesel engine and have been designed to be more efficient and more emission friendly than previous models. Evolution Series locomotives are equipped with either AC or DC traction motors, depending on the customer's preference, though admittedly there is little sound difference if any between the two. All early GEVOs were delivered with the Nathan Airchime K5HL air horn. Later GEVOs started to recieve a slightly different K5HLL horn. Most if not all have been delivered with a Graham-White 373 E-Bell. This E-Bell is tied to the horn circuit in the locomotive and will play automatically when the horn is played. The ESU version also has this new feature. The bell can be activated by either pressing F1 or by pressing the horn using F2. The "Auto-Bell" can be turned off by removing the the Auto-Bell sound slot from F2.
Another feature of the prototype is "Smart Start". For the sake of both emissions and fuel savings all GEVOs have been built with an auto shutdown/auto start feature. After the loco has been idle for a period time, the engine will shut down on its own. If the prime mover cools to a certain temperature the loco will automatically start again to keep from freezing.
Recorded from a GE ES44AC
This project has an automatic low & high idle. It has a single late (silenced) exhaust stack.
File also contains an "Isolation Switch" Mode on F15 when Standing Still.
Pressing F15 while not moving will lower the prime mover and lock the motor. F15 must be turned off to begin moving.
Another Mode is "Reverser In Center Position". When pressing F24 while stopped, the motor will lock so you can throttle through the notches like the prototype in neutral. F24 must be turned off to begin moving.
This project has "Run 8" mode. When turning on F26 with F28 off, the prime mover goes to run 8. Turning off F26 returns the prime mover sounds back to normal mode.
This project has "Coast" mode. When turning on F27 with F28 off, the prime mover goes to idle for coasting purposes. Turning off F27 returns the prime mover sounds back to normal mode.
You can still use F26 and F27 for manual notching. You have to keep both F26 and F27 off before pressing F28 to turn on manual notching. Once F28 is on, you can use F26 to notch up and F27 to notch down. F26, F27, and F28 must be turned off to return to normal mode.
This project has "Load" mode. When turning on F29 with F15, F24, F26, F27, F28 off, the prime mover goes into load mode. While you are using load mode, the prime mover will notch up 1 or more notches based on primary load settings(CV104). The throttle notches up using speed instead of requested speed while using the load feature. F29 must be turned off to return to normal mode.
Prime mover volume selection mode. By default the prime mover has volume dynamics. Meaning idle is soft while notch 8 is loud. This is very prototypical. The next option is volume maxed out. Meaning idle and notch 8 are the same volume. This is more suitable for people who like it loud.

This file is also equipped with a Smart Start feature that cycles the prime mover on and off at intervals of your choice if the throttle is left at Idle and the loco is stopped.

Auto Bell:
Many Second and Third Generation locomotives have been fitted with an Automatic Bell that is triggered when the horn is blown. In MANY cases this cannot even be bypassed on modern locos. Before the FRA mandated this feature on new locomotives the bell was of course turned on and off separately. Some locomotives were delivered with a manual bell and have been converted to an automatic bell. This creates a challenge in sound file creation.
We realize that not every loco with a particular prime mover had this feature. As such we have built in an option to turn the feature on and off. We will set the default in the file to be what is most appropriate for the particular file.
To turn the feature OFF - Auto Bell OFF:
1. Remove the Auto bell sound slot from the function mapping chart
CV31 = 16, CV32 = 8
----------------------
CV311 = 4
2. Change the sound configuration of the Auto bell sound slot
CV31 = 16, CV32 = 1
----------------------
CV287 = 0
To turn the feature ON - Auto Bell ON:
1. ADD the Auto bell sound slot from the function mapping chart
CV31 = 16, CV32 = 8
----------------------
CV311 = 12
2. Change the sound configuration of the Auto bell sound slot
CV31 = 16, CV32 = 1
----------------------
CV287 = 1
Auto Bell Timer:
The Bell timer is amount of time the bell will play after the horn if the auto timer is active. The timer is broken down into 1/4 of a second increments.
CV169=4 - 1 Second
CV169=8 - 2 Seconds
CV169=12 - 3 Seconds
CV169=16 - 4 Seconds
CV169=20 - 5 Seconds - Default
