The DZ1000 uses a small microswitch to cut off motor current at end of travel, full point closure. Thus this circuit would not be of value here, other than might give more zip to motor throw power insuring end to end lock (speculation).
I believe (use this info at your risk, maybe try on salvaged motor) that you could use this capacitor discharge circuit for Atlas motors, The two outside motor screws would connect to the control rails, assuming that rails are actually insulated from outside rail ground (might need to ohm-meter out those rails and cut jumper as needed to maintain all outside rail continuities. The wire you show as "jumper wire" would go to the switch motor center screw (which should be the common connection between both coils.) You may have to adjust the resistor for how fast the capacitor recharges after each use. The capacitor supplies the high current to get motor to move but then dies away so coils aren't being operated at full voltage and over heat. Suggest start with high value resistor then decrease until you get motor to just snap reliably but not overheat (measure coil voltage after operating, ie a car sitting on control rail or holding down the remote control switch). Higher the value the longer it takes capacitor to fully recharge but lower voltage across coil.
Of course you can still connect your remote control box wires to the two outside motor screws and its common third wire to outside rail ground.
Hope this helps.
