Hornby curved points radius?

Am I correct in thinking the inner rail is second radius and the outer rail
is third radius? I ask because the leaflet I've got from Hornby says they
are both the same radius.

According to the illustration of their TrakMat, it doesn't match the curve of the 'large radius' platform section as supplied with the Country Station but it does seem to mirror the third radius curve at the other end of the TrakMat. It also begs the question of why Hornby doesn't yet offer a third radius platform section.

That would imply a *very* sharp curve to create the angle.
Think about it, or look at the picture on the Hattons web site (unless you stock them and can check). The two radii of a curved point cannot be the same unless it is also a Y point.

Not necessarily with points as modelled by Hornby et al. The fixed rails of the two curves could be the same constant radius, but the blades supply the transition.

On Hornby (and Peco Setrack) curved points, both arms are second radius. An illustration on the Hornby package shows how they fit with other track. The inner arm is a 33.75 degree curve, while the outer arm is a 67mm straight section and a 22.5 degree curve (a single curved track is 22.5 degrees). If you add 2nd radius curves to both arms to make a 90 degree turn, the tracks will be at standard Hornby/Peco 67mm spacing. I have them connected in 3's to form a curved transition from 2 to 3 tracks (using flex track to bring the track spacing to 50mm). I could post a link to a photo if anyone is interested.
(Shame on John for not knowing about what he sells!!)

I think you're right, but I have some Peco curved express points which are third radius and bigger-than-third.

I think those are combined 36" and 24" radius.
There were also some setrack curved points produced before the current issue. These were much tigher than the present models are were excellent for derailing locos! ;-)

* Those are the Peco Streamline curved points.
I have a number of the old Peco Setrack 1st radius curved points in my fiddle yard, where space is at a premium. If they're carefully installed and negotiated slowly, my locos and rolling stock don't (usually) derail, even the current Hornby Black 5 with its fully-flanged centre driving and tender wheels. (I don't know how an 8F would manage.)

OK, usually. the N2 always comes off, though, as does the A3. Bah!
