Actuating block with 022 turnout anti-derailer

I'd kinda like to see a wiring diagram for the #1 circuit that's working OK, but...                                                                        For now I'm assuming you are using single-coil relays for your blocks that require constant power to stay thrown and they are activated when the insulated track rail (or non-derailing switch rail) is grounded. In that case for #2 I would suggest setting up a second relay connection to the switch rail identical to what you've done with your insulated track rail. That way both circuits are independent and either one can cut power to the block. Also, the non-derailing switch rail will work normally; i.e. only when a train passes over it.  Just make sure on #2 circuit the ground wire to activate your relay is connected directly to the non-derailing switch rail. Hope that helps.

I am using block sense relays like this

It's interesting you should mention this because  I was having a conversation with a friend and recalling -- or trying to recall -- some circuitry I used back in my 022 days circa 1960 +- a few years.

I never liked the non-derailing feature of the 022 turnouts;  after all, if the turnout is thrown against the train with a powered turnout, it shouldn't proceed through.  So I tinkered with changing the non-derail feature into a 'remove power' circuit, and here is how I think -- remember, it's been 60+ years -- it worked:

  I removed the fibre pin -- not that easy -- from the one side and moved it to the other outside rail.  I then installed fibre pins in both outside rails 'an engine length plus' from the turnout.  Now the only common feed to that section of track was through the non-derailing circuitry.;  hence, if the turnout were against the movement, the train would stop.

I did not use this extensively, as there weren't that many locations that justified it;  further I was leery of feeding up to four motors + loco lights through the contacts in the switch machine.

Does that circuit sound correct ?  Anybody else try this ??

Bonus question:  The 042 manual turnouts removed center rail power to the non-aligned side, didn't / don't they ?

Edited to add:  i must be forgetting something, because the locomotive's trucks would bridge the fibre pins.  Perhaps this was used only on dead end sidings, or passing sidings where the turnouts at both ends were wired like this ??

Interesting solution to solve that problem…   On my layout I have a 45 crossover just after the turnout, if I didn’t my problem would be solved.  I suppose I need the sense block relays on both sense sections to go to a third relay to kill the track power to the block.  That way the anti derailer would be isolated and the other dense block would not back feed and trip the turnout.
