atsfguy:
 It is just interesting to watch. I doubt you would find even one on my railroad, for as you say, it can be done by other technologies.
 I always enjoy reading your posts, combining facts with humor.
 As always, thank you for contributing your very extensive knowledge.

If you want a slick switch throwing arrangement combine the one-touch Tortoise control https://rpug.pdc.ca/index.php/topic,751.0.html with this little circuit. There's that handy 555 chip again!


Circuit diagram from ElectroSchematics.com (saves me from a lot of drawing  ;) )

Now you have touch on / touch off with no mechanical switch. Connect the outputs from any home brew logic circuit, DCC decoder, or RP LM/AM to pins 2 and 6 of the 555 and you also have logic control of the turnout switch. Easy peasy.
