ESU ‘Hifi’ Sound Decoder For The Class 69

In order to meet the demand for freight locomotives, the British GB Railfreight GBRf had 16 examples of the six-axle freight locomotive class 56 extensively converted with components from class 66 from 2019. The EMD 12-710 twelve-cylinder two-stroke diesel engine has an output of 2390 kW and generates the energy for the six electric motors. At 130 km/h, the Class 69 can travel faster than its technical sisters, the Class 66. The engine driver’s workplace has been upgraded with new instruments and better noise insulation..

Different starting processes can be selected with F1: 1x press button = warm start / press button 2x = false start / press button 3x = cold start

F2 slows down the locomotive slowly.

F5 enables the heavy load mode: The diesel notch is always one up compared with normal operation. If you want to jump two notches, simply set CV 104 to 150 (instead of 130).

F8 turns on the manual ntoching. Once F8 is on, you can use F7 to notch up and F6 to notch down. F8, F6, and F7 must be turned off to return to normal mode. If F8 is off and you press F7, the prime mover will run to full speed.

F14, F18 and CV 170 value 0 or 1, can switch between a “normal announcement” or an announcement “with gong”.

F9 can increase the speed of the spirax valve by double-clicking it. The speed levels are slow, medium and fast.

17 will bring the locomotive to full stop..

F28 and CV 164 = Value 0, 1, 2 or 3, can switch between different rail joints (three coupler can be activated with CV 165 = value 1).

F29 and CV 169 = value 0 or 1, can switch between the “Automatic Warning System (AWS)” or the “Train Protection and Warning System (TPWS)”.
