The way the non-derailing feature works is when a train comes in contact with the insulated rail on the switch, if the switch is in the wrong position, it throws. If you don't have an insulating pin in the end of that segment, it will try to throw constantly, and you could burn out the motor.
In the case of your crossover (the curved legs of the two connected right hand switches) both outside rails get an insulating pin.
To ensure power, you might need a lock on or other method of feeding the outside rail. See if the train works. If it stops add the feeder.
