Sound Car F.A.Q's

How do you control the loco and sound car at the same time?

 

Basically the boxcar becomes just another loco. Think of it as a dummy. The box is a better form for the sound and is more generic and flexible so it can be used with many different locos. It fits equally well with steam or diesel OR a C&NW or CB&Q consist.

You can assign the car a unique address and consist it to the desired loco or you can assign it the same address as a loco you are currently using.

 

They will both respond to the throttle and functions simultaneously either way

Can you tell where the sound is coming from? 
 
I dunno.  I think if your hearing is that keen, you'll be able to tell it is a recording and you'll hear the gear whine of the powered model engines too.  I think it is more noticable with HO scale than N but generally the sound is in the right area.  Also, it is certainly more detectable on a walk-around type layout where you are with the lead loco constantly.  I don't personally find it offensive but sound is very personal and good for me is really only good for me.
 
At one foot, it is easier to pinpoint the source.  At three feet, it is pretty tough to determine the exact source.  Distance from ear to rail plays a big role in your perception. 

Will the sound car work on DC?

 

Generally speaking, not well.  All of the decoders require a minimum of roughly 30% throttle (roughly 3 Volts) before the sound will start.  Then you do not have control of the bell and horn/whistle.

 

It's really not a good fit.  But, if you can live with the compromises... it will make sound.

 

I am told by a client to use the following settings with a Soundtraxx Tsunami to gain control of the bell and horn/whistle on DC.  Apparently the sounds can be triggered by a quick turn of the throttle up and down.

 

For Steam

 

CV13 = 1        

CV29 = 6

CV139 = 63

 

 

For Diesel

 

CV13 = 1

CV29 = 6

CV197 = 31

Why does the resistor on the motor circuit get really hot?


The resistor is included in the kit to facilitate CV readback when programming the decoder on a program track.


Since the resistor is soldered to the motor leads, the decoder supplies voltage to the resistor in operation.  A resistor dissipates energy in a circuit.  The by-product of this function is heat.


You need to reduce the amount of energy supplied to the resistor to reduce the amount of heat generated.


When used to simulate a motor load on a DCC decoder, you must reduce the maximum voltage supplied to the motor circuit.


Most settings are made to NMRA specified CV's 2, 3, 4, 5, 6, 66 and 95 so they are common to all decoders.  Every decoder is different though so refer to your decoder manual for specific detail.  


Refer to the section below for setting used by SBS4DCC in our R-T-R sound cars.

I am using a LokSound v4.0 or Select decoder and the engine sound doesn't change with the throttle?


LokSound decoders use BEMF to sense changes in the load on the motor and use that feedback to affect the sound being played.


In their steam files, greater motor load results in a labored chuff sound while a reduced motor load results in coasting (no sound) chuff sound.


The same thing happens with diesel sounds.

To correct the problem, simply turn off BEMF.

CV49 = 18


I am using a LokSound v4.0 or Select decoder and have added a Keep-Alive module.  Why doesn't it keep the sound going for very long?


LokSound decoders are the first brand to incorporate a timer on the Keep-Alive circuit.


This can be a valuable tool when using brake-on-DC and similar settings to control the stopping time of a loco.


I can also be handy to limit the time a motor keep running when power is lost.


Since the default is set very low, it does require us to change that setting to get the maximum amount of Keep-Alive time when used in a sound car application.


To correct the problem, simply set the Power Pack bridge timing to the maximum value.

CV113 = 255


What are the default CV values used by SBS4DCC in the R-T-R Sound Cars?

The following lists the CV settings used by SBS4DCC for the most common sound decoders for our R-T-R Sound Cars.

The settings assume the decoder is new and all CV's are set to factory default settings.  Please note that a decoder reset may not necessarily restore all CV's to the as-new default values.

The settings assume the active address is the short address (refer to CV1), Analog DC mode is disabled, and all functions are active in consist.
