Converting a 3469 ore dumper for use with atlas track accessory rail

Return your wiring so that the wheels are ground (common).

Then, since you have Atlas track, you need to get their Accessory Rails kit #6097...

...and install it.  Easy to do.  In fact I used this kit to add the 'shoe' rails to Gargraves track on my layout.  Would do for Ross, too.

Of course, if you really want to fuss and DIY, you can do the same thing with a couple of straight lengths of #14 solid copper wire, bent at both ends to extend down through the ties (drill holes therein) to below the table.  Connect these to a n/o button and on to your accessory hot voltage source.  I've done this, too.  Same amount of time/effort, really.  The DIY method worked out for me a couple of times because I had lots of home wiring #14 wire and an assortment of n/o buttons.  But the Atlas kit is 'slicker' in that it tends to blend in with the track better. 

I'm sure others have a different approach.  Stay tuned.

FWIW

When I do that, which I have done in the past, then one of the rails for the kit has to be hooked up to ground , right?  Or are both rails then hooked to the A terminal. I don’t have the instructions any longer and can’t find them any where.  Sorry forgot to mention I was using the accessory rails already.

This may help...

6097 Accessory Rails

Unfortunately, I don't have the 'blister pack' instructions any longer, and oddly enough I can't seem to find such documentation available on the Atlas website, either.  Very strange/frustrating.

I found the instructions on the blister pack from the bay.
according to this the common goes through one rail which means that one of the shoes should be hooked to ground. Am I thinking right?

The coil that dumps the car has two wires, they go one to the accessory shoe on each truck.  Neither wire is connected to the cars frame or gets any power from the wheels.  To dump the car one accessory rails is connected to power and the other to common. On coil coupler cars, to uncouple the car both accessory rails would be connected to power. On the coil couplers one wire from the coil is connected to the truck frame and it gets common power through the wheels. The disadvantage of this system is that one coil coupler uncouples when the unload feature is used and both ends uncouple when the uncouple button. This problem is a result of the uncoupling track being left over from the prewar box coupler era. With box couplers both couplers have to be energized to get both hoods to lift at the coupling to be uncoupled. All this went away when Lionel introduced the 480 style tab couplers.

I think I may have it figured out. I didn’t reconnect the other end of the positive wire to the coil. I need to connect that one to the one positive lead coming in and it should work. 🤞🏼🙏🏼  At the doctors for the wife’s MRI so will check it when I get home.

Nope still not working. Anyone help?  Please!!!????
