ZSWA Wickham Trolley ActiveDrive User Notes V17.06
Please spend a few moments to read these notes which have been produced so that you may obtain the maximum satisfaction from your new sound scheme.
The sounds should work perfectly when the decoder is fitted correctly. Individual locos may require some fine tuning that you can achieve with your DCC controller.
The sounds have been programmed in such a way that you, the user, may change the way that the sounds respond to your driving style or needs. This avoids the need for reprogramming and all the additional costs that would imply.
Throttle Response Scheme.
As supplied, the decoder will produce the sounds of a Wickham Trolley with a full load of passengers a wagon.
After the start-up routine the loco will stand with the diesel engine ticking over at idle.
The sounds will respond to the throttle control in the following way:
Select speed step 1. The engine will increase power to get the loco moving, and will continue at high power. The sounds will spool down to idle on deceleration.
The model can be driven in this way without ever needing to use any control other than the throttle.
You will hear gearbox whine which varies in pitch with actual road speed, not engine speed, to give an indication of acceleration/deceleration.
For something more immersive there are extra control features to further enhance your driving pleasure.
Heavy Train/Light Engine Mode Selection
The default setting is for ‘heavy train’. Inertia is high so acceleration (and deceleration) is restricted.
Activated by F5, Light Engine enables multi-function changes with one key. The switched features include reduced inertia setting to allow more rapid acceleration and engine sounds which are quieter
F5 can be operated at any speed to give another way in which the engine sounds at a given road speed may be modified instantly.
Gear Changing
It’s possible to simulate gear changes quite easily as follows.;
When the engine achieves a steady power sound, reduce the speed steps by 1 (or more) and the engine will spool down to idle.
Any subsequent increase in speed steps (1 or more) will cause the engine to rev up again.
Working Loco Brakes
The Brake Key will simulate brake applications. F2 can be ‘dabbed’ or held for varying durations. The sound will respond accordingly.
If the throttle is reduced in advance, as a real driver would do, before operating the Brake Key, a braking force which will actually reduce the road speed of your model will be applied. This force will continue to increase the longer F2 is held. Short dabs will provide speed trimming, held down continuously will result in a controlled ‘Emergency Stop’.
The real locos rely on engine braking and a wheel-applied hand brake to slow down or stop. I have not, therefore, fitted a separate braking function in this project, so you may need to adjust CV4 to suit.
The sound of the applied brake will sound automatically just prior to the loco finally stopping. This can be adjusted within the project if required.
Tip: F5 temporarily reduces the value in CV4 to simulate Light Engine levels of momentum. Using F5 when in Heavy mode will shorten stopping distances.
PowerCab users please note that the Horn/Whistle button operates the same sound/function as the F2 Key, but set as ‘momentary’. This facilities the precise operation of the brakes and should be used in preference to the actual F2 key.
Other systems may have F2 set to operate as ‘momentary’ by default, or can be set to do so.
Audible Warning Devices
There does not appear to be a standard so I have included types of AWD I found fitted to Wickham Trolleys.
F3 and F4 have Klaxon sounds.
F7 and F8 have Horn sounds.
Mute
F key 19 provides a ‘Fade to Mute’ function. When engaged, all sounds will fade to silence; when disengaged sound will return to previous volume setting by fading in.
Live Volume Control
Provided the sound is switched on and the ‘fade’ button is not active, it is possible to change the overall volume to suit changing needs.
Engage F17 and the sound levels will gradually reduce, eventually to silence
Engage F18 and the sound levels will gradually increase, eventually to maximum.
In each case, disengage the F key when the desired level is attained. Set F17 and F18 as ‘momentary’ if your DCC controller allows you to do so.
Note: If the volume controls appear to not function, check that F17, F18 and F19 are disengaged before making a further attempt.
It’s now down to your skill and knowledge to simulate any eventuality!

The table shows the project defaults; you can always return to these by programming CV8 = 8.
The Momentary/Latching column shows my recommendation if your DCC system allows you to assign this choice to that F key.
The Sound CV Column shows the CVs which contain the sound for the respective F keys.
The Sound ID is the value in the Sound CV used to assign the sound sample. If there are alternative sounds of a similar type they will be shown in parenthesis and the project default will be shown in bold. These values will differ between sound projects, so only those shown applicable here.
The Volume CVs always apply to the F keys shown, whatever sound is actually installed. If there is a sound assigned to these F keys, the volume of that individual sound may be varied, in isolation, by changing the value in the respective CVs shown. Value range is 1 – 255. (0 is equivalent to 255).
As an aid, these are the values equivalent to a range of sound levels:
