22 1/2 degree crossing

What brand of track?

What kind of layout are you trying to create?

Think of it as half the angle as a 45°. If you are just making a figure 8, you could make a giant one with 34, 072 curves. There are a lot more possibilities of course. An 072 switch crossing a parallel straight track would need that angle too. The list goes on. Basic geometry is the key. A little imagination helps too.

ok I have a 22 1/2 degree crossing and can't seem to figure out how to use it

A crossing of this type is often used as the "diamond" in a double cross-over situation for parallel mainlines.  With MTH's ScaleTrax, for example, the #4 turnout frogs have an 11.25-degree angle.  So a 22.5-degree crossing works perfectly for a double cross-over.

David, a little poking around leads me to believe that he's using Fastrack. Figured it out after I asked the questions above.

22 1/2 degree crossing is used with curves that take 16 to make a circle.   One curve section turns 22 1/2 degrees. 

Yes I'm using fastrack. And I do want to use it in my yard do I need a 072 switch to cross a parallel line then?

Best use of any crossing in 3 rail...

Especially in a yard with slow speed small wheel base locomotives going over it - its just like pumpkin flavored beer:   You will thank yourself later!

J Daddy, I'm not sure why, but I like your advice here, especially in the picture. 

the center rail gap in a shallow angle crossing can often be rather large which is sometimes a problem with pickup rollers maintaining power contact.

Ok got it

Man,

You have been emptying the tubs of track!  The 22.5° is in front of the small building? I like the light end/dark end. You can get the switch lanterns for the remote switches. The light stand/extension isn't that expensive, I thought I saw a couple with the lights out.

Have hope. V V S is curable.

Since Fastrack does not have a #5 switch, or a switch that turns only 11.25 degrees, there is not many uses for a 22.5 degree crossover.  Besides the example in Raiderofcoffins video, with Fastrack I can think of only a couple of other uses outside of two separate loops crossing at that angle.  An O-72 would also work in place of the O-60.

Other track types have a #5 switch that with the 22.5 degree crossing will make the double crossover David mentioned.  Note that Ross' Regular switch is only 11 degrees, so it doesn't work for a double crossover without some tinkering.  However, Ross does make a pre-made double crossover which is nicer than trying to build one out of separate parts.
