having a laugh here tonight. I picked up an all in one digitrax decoder with speaker and capacitor for £20 online. (Apparently an older model with old speaker) . Any who, I whacked an 8 pin plug on the end and stuck it into my A Class. After a little while of an a class with a steam sound, the wonderful NCE powercab let me pick a pre installed American diesel sound track. You know, apart from the American horn, it s alright.
