Favourite DCC feature.
 

Like it or loath it DCC is here to stay and analogue dinosaurs like myself are a dying breed.
It's pretty clear from comments already made on this forum that DCC offers many different features but if you could only have ONE, what would it be and why?

Well the DCC feature that really blew me away when I saw it was remote control coupling & uncoupling on locos/units - because I've always felt that the couplers on OO rolling stock looked really out of scale and naff (until now).

For me John, it has to be sound. The sound of a train pulling away with the steam and whistle etc. Even a tin can pulling hard makes it all so much better.
