Irish DCC sounds.

Wheeltappers DCC Sounds are developed to use the full potential of the ESU Loksound V4 Decoders. 

We, therefore, suggest that you study the Function key list to see the features which are unique to your locomotive.  

Now with the new 'Power Drive' (PD) feature option.

The new 'Power Drive' feature allows you to increase or decrease to coast the engine rev's without affecting the locomotive speed simulating a locomotive with a heavy load pulling away or coasting down a gradient.
When you have reached your required speed just press function button F5 and the locomotive will keep traveling at that speed.
You can increase or decrease the engine rev's as you like without affecting the speed.
You can now apply braking by pressing F6 function button stopping the locomotive and its train quicker.
The throttle must be at idle and F5 must be off for F6 Braking to work.
We have found the best way to drive your locomotive with the 'Power Drive' feature with a heavy load is to first press F5, then increase your throttle to the required rev's, then release F5 and back on again effectively using F5 as an increase in speed toggling it off and on to simulate pulling away with a heavy load.
With F5 still on you can increase the throttle up or down to simulate wheel slip.
You can use this method with the brake application F6 again with both F5 and F6 on you can toggle F5 on and off to slow the train to a halt but your throttle speed needs to be set at zero.

Both versions (normal and 'Power Drive') are available so please choose carefully the option you require.

Other features include buffer clash, set the function button when approaching the stock and as you stop as the loco hits the buffers the clash sound will be heard, releasing the function button will give you the coupling hook sound.(newer versions)

Cab lights (where fitted) will give a florescent light flicker as they turn on and the cab light will go out when the locomotive is moving off or in motion.

F1 while the loco is moving will mute the sound.

When changing direction you will here the driver walk from one end of the loco to the other on locomotives fitted with catwalks, this will be turned off in shunting mode.(newer versions)

When the locomotive slows to a stop the Dynamic brakes (201 and 071 locomotives only) automatically come in and the engine rev's will increase, as the locomotive stops the fan will come on to cool the motors and the compressor will come on to replenish the air when the brakes (F6) are released.

One press automatic uncoupling works in the following manner:-
Drive the locomotive with its train forward over the uncoupler (magnet or ramp depending on your type of coupling) and stop with the coupling between the locomotive and first carriage over the uncoupler.
Press the corresponding function button and the locomotive will move in the reverse direction allowing the couplings to unlock and then move forward disengaging the coupling.
This can also work in reverse with Kadee couplings where the carriage is still over the magnet.
When the locomotive pushes the carriage back from over the magnet and when clear press the function button and the locomotive will move forward and then reverse to couple to the coupler.

Each IR class 121,141, 181, 071 (NIR class 111) and 201 uses a General Motors Electromotive Division (GM/EMD) two stroke engine although of differing HP rating and configuration. 
The 121 and 141 shared the same prime mover type initially but as engine renewals were required some of classes 121 and141s were re-engined with the same prime movers as in the more powerful class 181s. 

You may notice both similarities and differences between classes as certain sounds are common to all types of locomotive but some have subtle differences.
Driving features include HEP (Head End Power) on the 201 class. Engine revs increase with dynamic braking on stopping (201 and 071),directional head and cab lights (201 and 071), cab lights will turn off when locomotive moves off if left on (201 and 071), tail light off when pulling a load (071),driver walking from one end of the locomotive to the other when changing direction (141/181 and 071),station announcements (destination can be changed by setting CV48 0-8) and radio communication(071 and 141/181)and extended startup with failed start on some locomotives(201 and 071).

As the condition of the locomotive can affect the way in which the locomotive responds to control
There are 3 slightly different engine sounds on the 141 and 181 which add variety and the ability to add realism to a consist configuration.

You also have the option of the class 141 with the GM 567CR engine and the class 181 with the GM 645E engine.

There is also the option of a special consist configuration consisting of two sound decoders matched to each other featuring directional sounds and different engine speeds and pitches which are unaffected in the motor speed range.
These two chips have been specially matched with identical CV settings to run as one locomotive command.

Steam locomotive sounds have been produced from actual live recordings enhanced by some archival material which adds character to the project.

All recordings have been taken at various locations at various times of the year.

Check the function lists for features unique to each locomotive.

Some features will not work on 'Power Drive' or normal drive locomotives.
