The brake wire from the controller (red) connects to the right hand track rail looking in the direction of travel. That rail is connected to the negative side of the power supply.

Rich, would'nt positive wiring have pos.(+) wire from power supply
to white driver post? Black driver post to drivers' (left) rail in direction
of travel. Passenger (right) rail returning back to red driver post.
Brake wire can be spliced into that wire or run directly from red post,
back to negative (-) side of power supply.

Sorry, I got that backwards. I did correct my original post, but once again for a positive polarity track the red wire goes to the right hand rail looking in the direction of travel, which is also connected to the negative side of the power supply.

I've read both topics- I don't think it's possible to wire a brake circuit into the stock AFX terminal piece, and f you could you would have to hack it up so much you might as well just build lane stations and do it the right way with 3 pole hook ups and the diagrams people have provided. To add even more confusion, I believe the diagram on the Parma box is wrong for HO tracks. The big concern about polarity is very important if someone decides to use an electronic controller on your track.

One thing to consider about adding a brake circuit to an HO track; You need to make it proportional with a reostat or it will be like throwing out an anchor when you let go of the trigger. It is very difficult to drive an HO car with brakes and no adjustability. If you're looking to add this a stock track power terminal I get the feeling you're running mostly stock HO cars which don't need brakes.

If using the Tomy track terminals cut off the plastic plug box, bend tabs down perpindicular
to track piece & solder wires. (2-track power & 2-common) I DO NOT recommend this method
because the track tabs will result in negative wired layout. When I had my 6 lane Tomy track,
I used regular straight pcs. w/4 soldered wires to proper rails for a positive wired layout.
The Parma wiring diagram is for larger scale slot cars & will be opposite of a desired Ho
positive wired track.

HO tracks have the negative rail on the right looking in the direction of travel, the other scales are all the opposite.

Correct. That is what's shown in the picture.

You just need to be careful of what "power" you're talking about, because there's Power from the power supply, which is wired in white and goes from the supply to the controller, and then there's Track Power, which is wired in black and comes out of the controller and goes to the driver's side rail in the direction of travel.

Slotking, does this condition vary as per manufacturer & class?
By manuf. I mean T-Jet, X-2 & G-3. For class- club stock, SS etc.
