Opposite Dim Control explained
 

 

 

 

 

Opposite dim control. Another lighting feature provided by TCS is that the decoder can make the headlight that is opposite to the direction of travel dimmed (CV 61 value of 32). This would be used in a switching yard. When a person is in the yard they always need to know if there is a locomotive present. Because of this, both headlights are required to be turned on at all times. However, the locomotive opposite to the direction of travel will be lit at half brightness. This way, if you're walking through the yard and you see a headlight at full brightness you know that there is a locomotive and that it might start moving towards you. If you see a headlight at half brightness you know that there is a locomotive present but that if it moves it will be moving away from you.
If CV61 has a value of 32 in it – the opposite headlight (white or yellow wire) will be dimmed regardless of the values in CV 49 and CV50.
NOTE: Because of the fact that CV61 controls more than just this feature, you should read HERE before changing the value in this CV because you may lose other features.
