I am new to Atlas switches and was reading about non-derailment...

https://ogrforum.ogaugerr.com/...ard-power-schematics

That thread is from 2013... I should think things have evolved.  How do you have your Atlas Switches set up for non-derailment?  What switch motors are you using?  Is ASC2 really any better than ASC?  My head is kind of spinning right now... info overload!

Any guidance to get me kick-started is greatly appreciated.

THANKS!

Our local train club used Atlas O NS track and switches - great looking with a realistic rail cross section, but ...
soon it was apparent that the spring-loaded switches would perform the anti-derail function OK for locos and heavier rolling stock. However, our problem was: lighter-weight cars would not "push" the swivel rail and perform the anti-derail chore reliably -- so we had pesky derailments. We didn't know then that the tension was adjustable; we could have used that feature to advantage!

We noticed that Atlas makes a circuit kit that throws the switch electrically based on contact of the wheels and axle with an insulated rail section -- like the RC Lionel switches. We bought two of those, but we never got around to installing them -- and then the club dissolved. 

The Atlas switches had a short (1 inch or so) small rail piece at the entry straight rail. When it came loose, we re-glued it and soldered it in place, but that didn't hold for long. After some fussing with it, we gave up on repairs and replaced the switch with a new one.  With 20/20 hindsight, I now believe we caused the breakage of that small rail piece on our modular layout because of regular use: transporting modules from storage to the site, set-up, take-down, and transporting modules from the site back to storage; i.e., club-inflicted wounds to some switches, especially if the switch was near a joint of modules.  Very likely a switch with that small rail piece -- once installed on a permanent layout -- would behave as intended forever.

Back when I mixed Atlas and Ross turnouts on modules I would always use a Ross turnout at module seams and trim as needed.

Now all I use are Ross switches.  I find that I could slice through Ross turnouts at module seams without problems. 

When ever I shorten Atlas switches the abbreviated rail pieces seem to easily roll out of the spike heads without much strain.

Have not gotten around to installing the tortoise machines on my Ross turnouts as yet.  They are left to be thrown by traffic.  The track plan is a 75' long return loop to return loop dog bone with a 16' long passing siding in between.  They safely run both ways through all turnouts throwing the fully floating Ross points on a very regular basis.
