Turning off the braking feature on the TCS WOW decoder
Posted by Nevin on Monday, September 11, 2017 12:57 PM

I've put these into a couple of my steam locomotives and over all I am really happy with them.  The Keep-alive feature is truely a game changer.  However, as cool as the braking feature is for a mainline freight, it is kind of a problem for switching in tight situations (F7 is a 20% brake application for each time you push it, F6 releases the brakes).  I went though the documentation last night, but I could not find a simple way to disable it.  I'd like to toggle it off sometimes.  Any suggestions before I call TCS?  Thank - Nevin

There is no toggle from what this says (I thought there used to be).

It is possible to switch with prototype throttle, just takes some getting used to (and you have to pay attention).

Page 16 also tells you how to adjust the brake rate.

Rule 108: In case of doubt or uncertainty, the safe course must be taken.

Thank you, that was helpful. I think I will try to adjust the CV's for braking and see if I can tone it down for the switch engine.  I agree that switching with the prototype throttle is doable but we often have a lot less room than the protoype and it takes a lot more concentration.  Fortunately I've put up lucite barriers to keep cars from going over the edge of the layout.

IIRC TCS decoders come with CV 3 start momentum set for something like 30, and CV 4 stopping momentum is 95. Surprise  Something like that anyway. You usually have to hit the brake several times to stop the engine.

I just changed CV 4 to be equal to CV 3. Then I only had to hit the brake function button once to stop the engine. If I just shut the throttle down to zero, it drifts to a stop in the same distance using the brake takes, just doesn't make a squeal.

Switching with the brake is pretty easy once you've re-set CV4. As the engine approaches a car, hit the brake and it slows up and stops just as it couples up. Reverse the engine, and hit the brake button again and the engine starts going to other direction with the car. At yard speed, the engine usually slows and stops within a short distance, 3-4 inches maybe?

This is the answer to the problem.   I turned CV4 to 30 and now I have much better control over stopping.  The standard for the WOW decoder is great and very realistic (I have been lucky enough to have run a real locomotive so I know how the brakes are supposed to work), but for a small layout the standard is just too dangerous when there isn't enough room.  Thank you all for the help.
