The GE B23-7 diesel locomotive was first offered in late 1977. Featuring a smaller 12 cylinder version of the FDL engine, it is the successor to GE's U23B produced from early 1968 to mid 1977, but at 62 ' 2" long, the B23-7 is exactly 2' 0" longer than the firms U23B. The B23-7 competed with the very successful EMD GP38-2. General Electric also produced a variant, the BQ23-7, for the Seaboard Coast Line. A total of 537 B23-7's were built for 9 U.S. customers and 2 Mexican customers. This sound file is appropriate for the following locomotives:
B23-7, BQ23-7, B30-7A, C30-7A
Unlike our 75405 Early 12cyl 7FDL which is correct for The "U-Series" locomotives, this 12cyl 7FDL is more appropriate for the "Dash-7 Series" of GE locomotives.
While this prime mover is not completely accurate for the following locomotives it would also be an suitable alternative to break up the monotony on your railroad.
U18D, U20C, U23B, U23C, U26C, Dash 8-32B (B32-8), Dash 8-32C (C32-8)
Recorded from a GE B23-7
This project is a normal idle version. 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.

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
