This has now gone a bit further and i have had a major breakthrough with the upper approaches and have now come up with a maximum height increase of 150 mm at S10 (switch 10) and a minimum of 80 mm at switch S9.The short distance from S10 to S09 is 4.8 m which will give me a gradient of just under 2 % which is what the upper approach is. The long distance beteen those switches is about double the short distance so this will make the grade a bit less than 1 % which is all very manageable. Rgds Ian PS have your email.
