Hi Guys, Larry...,thanks for your thumbs up and encouragement its always appreciated. 
. Mark (Boyce) thankyou too and glad you're liking the project. As for the curves , I don't know exactly what curvature they are Mark, everything pretty much is done by the eye and guesswork estimation except for the essential use of a spirit level. The verticle boards on the fence are 6 inches wide so I reckon that back area is about 10 feet wide on the left side and narrows down to about 7ft on the right. I have never actually measured the length of the plot. I'd reckon the end curve on the layout L/H side already in situ must be around 4 feet radius or thereabouts ?? ....when I get to the right hand side the curvature will be tighter. The biggest O gauge loco I have is a B&O EM1 articulated so hopefully the finished curves will accomodate it. I also have a UP FEF 4-8-4 with a fairly long wheelbase so hopefully they'll have enough side play in their chassis . Pretty sure they'll be fine on the left hand side curvatures but the right hand side curvatures will of physical necessity be tighter.They'll be no problem for diesels or short wheelbase steam engines but the bigger steamers ...fingers crossed 
..... I'll just make the R/H end curve as wide as I can and hope for the best. If they go round the curves good and well if not ...well they'll be goin on ebay...
. (AFTERTHOUGHT>>>> when I'm refering to left and right I'm always meaning relative to looking out from the house).
