I sorry to have to bother you all but i just cant get any futher
My layout is a elongated circle at each end of the elongated circle

The first thing to understand is that whilst it looks like you have two left or right hand points you in fact still have a left and a right hand point. It's just that it is curved so that it looks like the opposite hand.

So start with a right hand point and curve it to look like a left hand point then superimpose a left hand point on top in the normal manner.

regards

Alan

Hi Alan,

That's not strictly true, a single-sided tandem can easily have both turnouts of the same hand. In fact that's normally the case where an outer road is the main road:

The same can apply to a 3-throw turnout, although in that case single-sided versions are quite rare.

Derek, here is a sequence of posts showing some of the constraints in creating a tandem turnout:

 topic 2394 - message 16119

Unfortunately tandem turnouts are not straightforward, and you do need to be reasonably confident with Templot to produce a usable result.

If you post some details of your radii and crossing angles, etc., we may be better placed to help. Or maybe you could post your .box file or a screenshot of your track plan.

By the way, I think in 15 years of Templot this is the first time anyone has mentioned using the TT-120 gauge/scale. It makes a nice change. :)

regards,

Martin.

Hi Derek,

If you mean this page:

 http://templot.com/companion/index.html?3_way_tandem_turnouts.htm

You are not going wrong. It's because I haven't written that page yet -- along with most of the other new Templot Companion pages. I'm sorry about that.

In the meantime there is an old video about tandem turnouts here:

 http://templot.com/martweb/videos/3_way_tandem.exe

Some amended notes to update it for Templot2 are here:

 topic 1487

If you could post your .box file here I'm sure someone will be able to help with the tandem turnouts.

regards,

Martin.
