Long curves

Is there a way to implement smoother easements at both ends of this long curve? Both of them look to be around 200 metres in radius, when it actually needs to be in the four digit range. See image below, where the curves abruptly end.

I am not a fan of adding heaps of spline points, due to the unavoidable inconsistencies/abrupt changes in radius. How many spline points should I use here to get what is around a 520 metre hairpin style curve to progressively reach about 603 metres in radius, and stretch out to something from 2000 metres to infinite at the end of the curve where the sharp edges are? I am still in the learning phase of such. Yes I am referring to the giant curve in the centre.

Thanks
 
I usually run several measurement arrows out from the center to places where I want the curve to be; on the ends, the center and at different angles around the curve, then use them to place the spline points and add additional ones as needed to smooth.
 
I use a spline point roughly every 15 degrees of arc to layout curves, I adjust that as needed for specific locations or geometry. I frequently use the old fixed track curves to lay out large or complex curves, a bit clunky but it works surprisingly well.
 
Sometimes I'll place a few more at the apex of the curve to keep that together while the outer legs tend to be spread out a bit more.

There are some curve templates available on the DLS. I can't remember who made them, but they're worth checking out. They come in various sizes and are scenery objects that the track is placed on or connect to at various points. The templates can be deleted later and the tracks connected where they were connected to the template if they worked that way.
