messing with the center rail on this DCS track plan could mess with the DCS signal.
Since I do it on some70+/- toggled blocks, I can assure you it doesn't.
It does not matter which side of the circuit that you interrupt.
Suit yourself. I'm with Gregg. The 99-44/100% practice is the way to go
If outside rails are unpowered, you'll get surges as cars with varying degrees of conductivity go over the gap. Then when the PS2 or PS3 board gets damaged, MTH will be blamed for poor quality.
To quote Gregg, "For that reason I'm out. . "
