#1122 turnouts

[balidas]

Actually, I was asking about modifying the 1122 to power it's switch machine from a separate accessory supply, but in reference to these 2 threads.

 Sometimes, when I have a question, I'm not quite sure how to ask it.

The 1122 is already wired for automatic operation, if by that you mean the non-derailing feature.  I thought you were asking about modifying it to power its switch machine from a separate accessory supply rather than from the track voltage.

Rob- Thanx for that link.

Bob- There is not a lot I would be reluctant to do in this case. I am simply trying to understand the various options and concepts of setting up a layout. I am also trying to understand if for instance, it's better to re-wire or not the 1122 for automatic operation, such as when you run 2 or 3 trains on one loop and you use sidings to change which trains run.

There will be no TMCC or Legacy control here. Everything will be run conventional, since, on this layout, all locos and operating accessories will be postwar, which I believe, is the term.

I have been doing a lot of searching but sometimes I end up with more questions then answers.

I hope that answers your question.

No, of course it's not necessary.  You can do it or not, as you like.  I'm puzzled why you asked whether it's possible in the first place if you are reluctant to do it.  Am I missing something here?

Are there any schematics I can study to see how it's done? Any recommendations?

 

Bob put THIS together for you 2 years ago...

Ok, so it is possible, but is it really neccessary? I will be building a layout, initally as a public display, but will actually be for my grandson. The size will be 8x16, or possibly 10x20, but no bigger. It will be all 027, with a separate loop of Marx. I have read several posts in this forum about automatic switching and sidings, which I have an interest in doing. I would like to use these turnouts as I like them better then the newer brown ones, but I don't have to.

Thanx for your time.

It is true.  However, with some difficulty, they can be rewired for a separate accessory supply.  The downside of this is that it becomes much easier to burn out a coil by stopping a train on the turnout.  This leads to two other fixes.  One is simply to disable the non-derailing feature.  The other is operation by capacitive discharge.  Some overly complex modules are sold for this; but it can actually be done with only a capacitor, a resistor (or lamp), and a diode.

Greetings,

Ok, I think I found some good info on how to test these switches, but the little I found said these can not be wired for anything other then track power. Is this true?
