Chattering switches

Chattering is an indication of a direct short, if you connect them independently, do they still chatter?

Why not call Z Stuff for Trains? I am sure they have seen it all.

I had the same thing happen to me with a pair of Ross tubular switches - but I didn't solve it, I got frustrated over the whole thing.

As I recall, what I thought was an insulated outer rail was not - that you have to make an insulated rail section on an approach track. Wait a pain. Makes it harder to have non-derailing feature.

What is going on is the switch motor gets a command to "straight", and when it get to the position, it gets a command back to "curve". The only reason why it doesn't sit there and hum is because of limit switches inside the mechanism.

This requirement would require a change in the track layout, so I started trying to use SCARM, and came across some other issue, then spring showed up.

This happen to me.. Wire one switch at a time and test.

It might be one of those sneak circuits....

Question for Illinois Central.  What is SCARM?

I haven't thought out what exactly you have done there, but chattering usually comes from the micro switch in the switch motor not completely being engaged by the cam that tells the switch circuit not to continue to power in that direction.

I have this with Fastrack switches as well at times, but in the Fastrack circuit, it isn't a problem unless you continue to lean on the controller lever. I ignore it unless I have nothing else to take apart and fix.
