peco track

This sounds like a typical e-Bay moron not knowing what he is talking about when he wrote up the description.  All Peco turnouts have a "catch" to hold them in position, if you want to call it that.  What you need to know is the size of the turnouts and whether they are Electrofrog or Insulfrog, not some meaningless term like "catch."

Yes they do. Do a search for Peco catch points in " Worldwide  E*** " or in the Peco catalogue.  They come in various scale and code height.

But, does Peco make such a thing?  I've nebver seen it advertised in the U.S.

They do have code 100 catch turnouts/points/derailers in their catalogue, I'm looking at it right now. Part numbers SL-84 (RH) and SL-85(LH). Don't know if they still make them though, my catalogue is a couple of years old.

You can scratch build it. Like my derail:

As far as im aware, they are still very much alive and kicking.

Code 75 and 100 rail. Not 83 though unfortunately. 

Yes that looks like what I saw But Still don't know what use they have

The answer is the posts above.

It is used to derail a run-a-way car so it does not go back down the main line and hit something,  like a passenger train. The orange one in my pictures is used in North-America. Same principal,  just smaller.  Those from PECO are more Euro rail,  like Wolfgang's scratch built derail device pictured.. 

Those cast frog derails are available from Details West I believe.

a similar design is used on BNSF's Conroe sub (non - signalled dark territory )to protect against traffic on the main track from entering a Chemical plant in case the main line switch was left open so that a train running 49 mph would not come rocketing into the plant, but would be derailed to travel parallel to the main track and not into the chemical plant. ( this scenario actually happened - engineer big holed it and stopped 18 ft from a load of ANHYDROUS AMMONIA coupled to loaded PHENOL and MEK -  Shortly after that the open point derails were installed.)  The Lord must have watching out for that crew - speed tapes showed they were travelling 37 mph over the 10 mph rated switch and were able to get the train stopped in less than 1/2 mile and did not derail.. just tore up the chain link fence gate and soiled some clothing.... true story , know the engineer, been at the plant.
