My latest issue when checking out my 022s is I CANNOT GET THE CURVED DERAILER TO WORK when shorting the CURVED outside rails. Hooked up one insulated track from transformer. EVERYTHING ELSE WORKS, straight derailer and switching????
Please send help, thanks again, Jerry

You do not need an insulated track hooked up to test the switch, just make sure the insulating pins are in the correct rails in the switch.
Disconnect the controller and try shorting the outside rails again to check the anti-derail function. If it still does not work, either the switch machine contacts need servicing, or the curved side connection strap on the underside of the switch is not making good contact.

If the curve leg works with the controller, the problem is the curve rail connection strap as Larry suggested. It is accessible by removing the bottom plate. The solder joints on these are small and frequently break. When re-soldering them be sure to make contact with only the tab of the insulated rail. The tabs of the insulated and live rails are very close and require a rather precise solder joint that can best be accomplished with a small tip iron. Good luck with the repair.
Check the solder joint I highlighted:
Thanks for the info. All the solder joints seem ok. Is there a way to check the joints that will uncover a problem even when they look good??
Attached is a document I just made since I am servicing my switches for my layout revision 2.
Do you have more than 1 switch, and does this problem occur on only 1 switch or all of them?
If you have more than 1 switch, and the problem occurs on only 1 switch, and you verify that the solder joints inside the switch seem to be ok, then swap out the switch machine from a good, working switch and see if that fixes the problem. If it does, than the switch machine needs servicing of its' contacts.

Jerome,
You can test the solder joint with an ohm meter or any kind of continuity tester. Attech a lead or probe to the curved rail connection strap and the other lead to the insulated curved rail to see if there is continuity between the two. If you don't have some kind of testing device, you can do it with transformer leads. Touch one to the strap and the other to the insulated rail. If it creates a short the joint is good. If no short there is no continuity and the solder joint is faulty.

My PDF attached above contains this test with photos.
bmoran4,
Very helpful. You have put a lot of work into your illustrations.
YOU GUYS ARE FANTASTIC !!!!! THANKS FOR ALL THE INFO
