I have NO intention of playing with toy trains or cutting out bits of paper ...
I am an engineer. I am not a "model railway operator" - I do NOT play with toy trains...
I am an engineer who is tasked with relocating parts of a vast loft layout into a garage layout such that the (now) wheel-chair bound owner may continue his lifetime hobby.

The simple point (no pun intended) I'm trying to make is that Peco are claiming the theoretically IMPOSSIBLE: -
e.g Code 100 large radius turnout (SL88/89)
To attain a frog angle of 12 degrees to an effective radius of 60" (as claimed) would require a chord length of 12.475"... such is IMPOSSIBLE with a component only 10.125" long.

"For every complex problem there is an answer which is simple.... and wrong"
Fully agree with that statement... & Peco are guilty of using the simple answer!

yeah - surely all this PECO frog angle & radius of curve would be sorted if Peco had the sense & courtesy to publish PROPER engineering drawings instead of photographs with pathetic rulers?
Radius? - DEFINE your AXIS
Frog angle? DEFINE your AXIS
I cannot comprehend how a supposedly reputed Manufactuter is determined to be so recalcitrant!!!!
