UCS Track Question ?

[cwburfle]

I must be missing something.

Its my impression that the wiring on the UCS and 6019 (027) tracks are different.
On the UCS (O gauge) track, pictured above, the top switch leaf (closest to the button) is connected to the coil, and the right hand control rails. The second leaf is connected to the power source (either the third rail or the accessory voltage post). Therefore, the coil shopuld be energized when either button is pressed.

On the 6019 (027 track) the top switch leaf (closest to the button) is connected to the center rail (power source). The coil is connected to the third switch leaf, along with the left control rail.  On the right hand (uncouple) side there is a spacer that prevents the second and third leaves from touching, and forces the third leaf to contact the fourth (last) leaf, which is connected to the ground. 
Therefore, the coil should only be energized when the uncouple button is pressed. Both ends of the coil should be connected to ground when the unload button is pressed.

What did I miss?

Since I prefer the setup on the 6019 (027) track, I rewire all my UCS tracks to work that way too.

Yes.  There will be some potential there as the magnet coil is grounded on one side.  Follow the current(with your car on the track and energized) in this schematic:

UCS Remote Control Track  - When Un-Load button is pushed, my 3472 Milk Cars operates as it should, but I noticed that when the unload button is engaged, that the uncouple magnet is also energized.  But with no car on the track the unload button does not energize the magnet.  I have the #3 wire from the controller wired to accessory post B on my ZW so I'm not using track power.   So  ....  when milk car is in operation - there is a sneak path for current to go to the uncouple magnet coil.  I checked the 3 UCS track sections that I have on my layout and this is same with all three.

So .... my question is - is this normal ?
