Insert Turnout in Plain Track

Matt Rogers · 20 June 2023

Really quick question,

But when you insert a turnout in plain track, is it possible to insert with the diverging road, and not the main road?

I set up a real simple 180 degree arc with a minimum 40 inch radius and transitions from/ to straight, and was hoping to start progressing a fiddleyard design.

Hi Matt,

I can't see what the advantage would be, a real turnout is handed, by which rail is the point rail and the splice rail, other than that the geometry will be the same.

Hi Phil,

having played with some more generous settings for the switches and crossings, I can see setting the 'handing' of the switch gets me close to what I am after.

Hi Matt,

You are probably looking for the substitution radius (called the external geometrical radius in Templot) to match into your 40" radius curve.

I have resurrected an old Templot video from 2005 about this, see:
