The EMD 645 family of diesel engines were designed and manufactured by the Electro-Motive Division of General Motors. The 645 series was an evolution of the earlier 567 series and a precursor to the later 710 series. The 645 series engines entered production in 1965. All 645 engines utilize forced induction, with either a Roots blower or a turbocharger. The 645 series has a maximum engine speed of between 900 and 950 revolutions per minute (rpm), an increase over the 800 to 900 rpm maximum speed for the 567 series. While only a few operating examples exist today, the 20cyl 645E3 was often found in the following locomotives:
SD45, F45, FP45, SD45X, SDP45, SD45T-2, SD45-2, and others
Recorded from a EMD SD45T-2
This project is a reverser based low idle version. It has a single turbo early exhaust stack.
File also contains a "low Idle" 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 go to "regular idle" and begin moving.
Another "low Idle" Mode is reverser in center position. When pressing F24 while stopped, you can throttle through the notches like the prototype in neutral. F24 must be turned off to go to "regular idle" and 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.

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
