Ummm.... except that you lose control when the train goes into a tunnel, or you
have areas of unreliable control on your layout. Losing control in a tunnel
would be a big deal for "serious" model railroaders that like off-stage
"staging" yards. Not such a big deal for any but the most ambitious Lego
layout, I suppose.
Personally, its the "unreliable control" aspect of IR that concerns me.
One thought that comes to mind is that if we can reverse engineer the IR
protocol, there is no reason we can't build repeaters or our own controllers.
You could sprinkle IR transmitters throughout the layout and wire them all in
parallel. With that, the loco should never be out of reliable communication
range.
An IR controlled turn-out motor would also be on my wish list.
