If you are going to stick with standad Hornby track you would be better to use 3rd radius track on the outside of that side of the layout. you need about 5" of additional width but you can get an island platform between the two. You could set up a complete loop which would add even more interest.

You need 1 single and 1 double 3 radius curve to set up the bay and double that to set up a loop (and another curved point)

I have spent hours experimenting with various combinations and it does help you to understand the geometry better. The Hornby Track Plans book is very helpful as well.

I am now in the process of designing a new layout which will use Peco Steamline track.

The other useful tool is the Tacksetta range of metal templates. I am now drawing the proposed plan out full size on wall paper backing paper and it amazinzing how it helps!

Hope this is useful.
