yep I think it was only a matter of time before we got rolling stock with DCC sound. If you think about it there is always a wall of noise generated by coaches/wagons when they pass you on the real railway, sometimes as loud as the locomotive itself. This is one area that DCC sound falls down in for me. All well and good having the locomotive fitted with sound, but without sound of squeaking, coupliers clanking and wind etc. coming from the rolling stock behind the illusion is ruined somewhat!
