Class 66 Horn mod for DBS 66 (GWE) and ECW

This mod enables a more authentic horn combination sound than the deafult source.
Note in order to have this combination Ive assigned preset combinations to play with high and low keys. For best result hold key down firmly until 2 tone has played out.
*Update 12/6/22 Now in addition to Horn replacement there are modifications to the Engine, bogies, and Cab.
*Update 26/6/22 DBS 66 Has changes Engine sounds, Reverser and throttle lever tweaks, Brake release and interior rattles. For GWE66 only (for now).
*Update 9/8/22 Small tweak to the bogie running sounds, to negate the abrupt approach sounds that cant be corrected.
