Atlas N Scale B23-7 Late Exhaust - 58925 LokSound 5 Nano DCC
Finger Lakes / Minnesota Commercial/ Santa Fe / Southern Pacific
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
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

2. Change the sound configuration of the Auto bell sound slot
CV31 = 16, CV32 = 1

To turn the feature ON - Auto Bell ON:
1. ADD the Auto bell sound slot from the function mapping chart

The GE FDL-16 prime mover was first used in 1959 in the General Electric U25B locomotive. Over the years little changed in terms of sound until the "Dash-8" series of GE locomotives was introduced. Known for their throaty chug and shaft driven compressor (rather than the more modern “Whoop” electric compressor). There was an interim period following the "U Boats" that began the era in GE called the "Dash-7s". During this time many locos started receiving exhaust silencers and the shape of the exhaust changed to the "Bathtub" type. This created a subtle change in sound. The following GE locomotives used the 16cyl FDL prime mover with this type of configuration.
Locomotives:
B30-7, B36-7, C30-7, C36-7, and others.

In the Mid 1980s GE changed it's 16cyl FDL design to include a different exhaust silencer, a new electric compressor often known as the "Whoop compressor" and changed some of the electronics of their locomotives. These differences among a few other led to a distinct change in the sounds from the GE 16cyl FDL often found from the U25Bs on through the Dash-7 series of the Locomotives.
GE's AC series of locomotives were introducted in 1994. They share the same carbody design and many of the internal components as the Dash-9 series, except they are equipped with AC traction motors instead of the conventional DC versions. The cab air conditioner was moved from the left (conductor's) side walkway to a position under the cab floor to make space for the six traction inverters (one per axle) that supply the AC current to the traction motors.
The "Modern" GE 7FDL 16Cyl Prime mover can be found in the following Locos:
Dash 8-39B, Dash 8 40-B, Dash 8-40BW, Dash 8-39C, Dash 8-40C, Dash 8-40CM, Dash 8-40CW, Dash 8-41CW, Dash 8-44CW, Dash 9-40C, Dash 9-40CW, Dash 9-44CW, C38EMi, C38AChe, AC4400CW

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.

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

The EMD 645 series was an evolution of the earlier 567 series and a precursor to the later 710 series. When the 645 prime mover entered production in 1965, a large series of new locomotive models was introduced. The turbocharged version was used in EMD's 40 Series (GP40, SD40 and SD45) in 3,000 horsepower (2,200 kW), sixteen-cylinder form and in 3,600 horsepower (2,700 kW), twenty-cylinder form. EMD also introduced the Roots-blown 38 Series (GP38, SD38) and turbocharged, twelve-cylinder 39 Series (GP39, SD39). All of these locomotive models extensively share common components and subsystems, thereby significantly reducing cost and increasing interchangeability. The GP38-2 and SD40-2 became the most popular models of the series and among the most popular locomotive models ever built.
This 16cyl 645E3 with Turbo sound file would be appropriate for the following locomotives:
GP40, GP40P, GP40P-2, GP40-2, GP40X, SD40X, SD40A, SD45T-2, SD40-2, SD40-2W, SD40-2S, F40C, F40PH, F40PH-2, F40PH-2M, SDP40F, SD40-2F
Export locomotives:
GT26MC, GT26CW, GT26CW-1, GT26CW-2, GT26CU-2
Recorded from a EMD SD40-2 "Snoot Nose"
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.
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.

The American Locomotive Company's model 244 prime mover was developed during the mid-1940s to power its post-war diesel locomotives. Interestingly, while Alco helped pioneer diesel technology dating back to the 1920s it had difficulty truly competing against Electro-Motive-Division due to reliability issues with its diesel engines. Before Alco began implementing the 244 in its locomotives the builder had spent most of the 1930s developing an earlier model that was used in most of its early switchers. The new prime mover was supposed to usher in a new era for Alco but instead saw it slip further behind EMD in the marketplace. During the early 1950s the manufacturer replaced the engine with the more reliable 251 that powered its Century series. It would prove to be the company's last engine as it exited the market before 1970.
This sound file would be appropriate for the following locomotives:
RS-2, RS-3, RSC-2, RSC-3, RSD-4, RSD-5

The ALCO 539 engine was developed in response to the perceived drawback that ALCO's line of diesel switchers had a restricted field of vision because of the high hood. Both Baldwin and EMC were offering diesel switchers with a lower engine hood that the trainmen could see over.
The 539T was equipped with the Buchi turbocharger, being made under license by the Elliott Manufacturing Company of Jeannette, Pennsylvania. The first 539T engines were used in S-2 switchers and DL-105 passenger locomotives built in September 1940.

This project is a normal idle version. It is an air throttle version. It has a single 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.

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.
