DCC user since 1996. Good old Lenz system. Bullet proof. I think the secret of DCC systems is buying equipment manufactured by a DCC specialist manufacturer.
Back to the 37’s, I have been playing around with the heavy train, light engine and three different brake functions available within the V5 decoder and all I can say is that it makes driving it so much fun.
I prefer this type of functionality to sounds of doors slamming etc.
