I've started putting down some cork roadbed on the end of the peninsula and on Rykene industrial area. The cork is 5mm thick and very easy to work with.<
This picture is from the left side of the peninsula. The incline here is close to 2,5 % and the sharpest curve on the layout is the one seen to the right in the picture. It's a 55cm radiuscurve, but it works fine and looks ok with most of the rolling stock I plan to use on the line.
