Did a little more work today.
I connected power and ground to the gantry crane. I soldered wire to two Ross pins then ran one outside rail to ground and the other to a toggle switch on the control board. I programmed the crane as accessory 1. To rotate the crane one selects ACC 1 and uses the red throttle knob on the Legacy remote. To move the crane along the track select '2' on ACC and use the red knob. To move the 'hook' up or down use the boost button. To turn the magnet on and off use the brake button. It takes some getting use to but this accessory is going to be a lot of fun.
I also changed around the position of my gantry crane. Last post I had the crane straddling the Gargraves track. I changed it so the crane now rides on one Gargraves rail and on its own track on the opposite side. The reult is a lot more room on the one side for crates.
I wired track out to the main line - finally - (where the UP caboose is)
I also tried a new approach for power for my custom built bumpers on Ross track. I have been soldering the lamp wire to Atlas O rail joiners and using them upside down on the Ross / Gargraves track but the rail joiners interfered with proper seating of the bumper plus the joiners were very loose. So I soldered the wire to Ross track pins. The fit of the track pins is a lot tighter but they do stick out a little.
Next week it is the approach track to the double crossover then the real fun begins.............
