Diamond scale turntable

Ok so I need some answerso n wiring the bridge rails for DCC.
I ran on wire down through the bridge to the wheel and soldered a wire from the pit rail. I have the other rail wired to the bridge tower and will have a bare wire running from it to a pole and then out the bottom of the layout. I feel like there will be a reversing issue of some sort or the need for a decoder of some sort to wire the bridge to the DCC bus.
HO scale Digitrax is my power supply.

thanks

A decoder is not required, but a way to reverse the polarity to the bridge rails of the turntable will be necessary. This can be done manually with a DPDT switch, or automatically with a Digitrax auto-reversing module.

So an AR-1 automatic reverse controller?
I got one so its all good

thanks
