I have most of my layout connected - some bits of track and points still awaited - attached image hopefully should show it; is basically 3 sides of a square, or "n" shaped. I would like a turntable on the right-hand side, however I do not have the skills to make or adapt an OO or N gauge one. So might need to wait until Hornby (hopefully) make one. I guess my other alternative would be to have a "reversing loop" (I think this is what it is called, but may be wrong!), again on the right hand side. I have never had/used a reversing loop - are they sensible? Should they be avoided? Are they simple to set up/control? All/any comments/help/criticisms gratefully accepted. Regards, Alasdair
