*GE GEVO-12*

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 Gevos have been delivered with the Nathan-Airchime K5HL air horn. Most if not all have been delivered with a Graham-White 373 E-Bells. 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 silencing the Auto-Bell sound slot. (CV32-1 then CV323 to a value of 0)

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. Our ESU version is also equipped with this "Smart Start" feature. If enabled after idling for either 1 or 2 minutes (Selectable with CV48) the engine will shut down and without doing anything to the throttle it will start again on its own. If at any time during this shutdown mode you would like to run your loco, just turn the throttle slightly and the engine will go through it's start up cycle and then allow you to move it. The feature can also be turned off if it is deemed undesirable.

Though all Gevos were delivered with Nathan K5HL air horns we've also included a few extra horns in case you wish to use something different. Due to the vast numbers of sounds included in the file we were not able to include our normal 16 horns, but we have included 7 for your choosing. These are Selectable by using CV48. Values 0-6
