Wow!. Thanks John and Stan for the effort you've put in. I think first I'll try going to half-wave with a diode vice the capacitor, and then go the Hall effect route.

Can the Hall effect sensor be used with the UCS's magnet fed AC, or should it be full-wave DC with a capacitor?

The belly of the Lionel dump cars is metal, so I doubt that the UCS would activate a relay armature through it.

Allegro MicroSystems reports that the A3144 is no longer available and has been replaced by the A1101-1106 family. I do see A3144 listed on Amazon from China. Jameco has the replacement A1104

Would these be suitable in your circuit?
