Hey all, Real quick, How many degree's offset it the divergent of a #5? I'm adding a small mine yard and I want to bring the divergent back to parallel.
Thanks!
It goes 1 foot vertical for every 5 feet horizontal...
or.... 11 degrees, 32 minutes, 13 seconds....
Can't help it...
I was a Civil Engineering Major...
With a Bachmann HO E-Z Track #5 turnout use
one 2.25" straight item no 44513
one 33.25" radius 12 degree curve track item no. 44509
to bring the divergent back to parallel.
12 degree 33.25"
/
2.25"
/
#5 === 9" straight
Thanks!

The frog number tells you the divergence.
No. 5 = one unit of separation for every five units of run.
No. 6 = one unit of separation for every six units of run.
No 11 = one unit of separation for every 11 units of run.
And so on. The "unit" can be anything you like. Inches, feet, centimetres, fathoms, astronomical units. It doesn't matter proving both are the same.
For the degrees of separation, you'll need the mathematics provided by Hunt below but usually we modellers just go by the frog number.

I am familiar with what the frog numbers mean, Just not the degree's of separation and thus what I would need to bring back to parallel. I'm sure If I bothered to whip out my Trig book I could find it but regardless, now I know.

"Bring them back to Parallel"?
Sorry, you lost me. Do you mean, for example, you have a switch leading into a siding and you want to bring the siding track back parallel to the main track?
In that case, you just put a curve that is larger than your minimum radius at the end of the diverging road of the switch to bring that track parallel to the main track and two inches on centre. That's typical centre to centre distance between track. NMRA suggests 1 13/16" as the "scale" distance but two inches is more convenient.
Is that what you were asking? I'm not sure because many modellers tend to over complicate things, not that you are doing here. :)

Hello People,
Great Answer !That opened a page in me that was not opened in a wile.I did study this long ago.Wow the things I forget! I will also keep this in my files!Thank You! Need more of this kind of thing here to keep some of us from walking the fence with a short fuse ;D
