Thanks guys and all good info. I do want to experiment with a router so I will do it somewhere, the viaduct section where the train will be below and the road would be a good spot, long straight bit and should be able to connect it easily to the plastic. The routed tracks do look more natural.
With the video I posted a couple of months ago the camber of the road construction in one spot sees the car loss a bit of grip as it twists. At least with the plastic I can play around with lifting or twisting once it is in final position. The problem is I can't really test the whole thing and then adjust the layout. I'm a finance guy and now need a civil engineering qualification!
I think I will solder pieces together where the boards meet and keep those free to move the boards for running repairs or adding electrics/ lighting etc. I saw one post on here where someone had even smoothly plastered or whatever he did to make it look like one piece. Braid over the scaley rails might be another idea. I don't think I will need to screw the plastic down, I will wind up trimming pieces to make it fit better and then solder it. With the looping road the curve inwards becomes tighter so in a couple of spots is not a very good fit now.
I guess I should have started something smaller but the design idea came when I decided to do something around the loft.
