Now on to some practical stuff;_Read this in conjunction with what has been said about my golden palm problem; at this stage i have opted to take the easy but not the most worthwile alternative of going in front of it.The scene is still my area 1, which i am reworking to make it fit in with my "Ell" development which connects area 3 with area 1. This is now part completed and i am running trains around a loop betwen the three areas but i am only utilising the front half of my reversing loop, which will be refered to as the ascending ramp. (up to the points which switches the train from going around the reversing loop or on to the "Ell")My ascending ramp is completed and i have a beautiful R2 curve and a very nice gradient of 2 % and it looks correct and works very very well.Now we are on to the desending ramp, which will go to the front of the palm; at about the middle of both ramps they unfortunately become adlacent to each other. At this point the descending ramp willbe behind the ascending and it should be the same height as the ascending ramp or about a centimetre higher. But as i am approaching this point in building the descending ramp, it is becoming obvious that opposite will be more likely; ie it will be about a centimetre lower.As i am now working on a gradient of 1.5 % down as against 2 % up, there is not much in it and everything i do must be pretty right.So i have decided to modify one of my spirit levels (i have 5) to accurately measure 1.5 % gradient. it is 220 mm long ( it is the one mentioned previously that sometimes has 2 bubles) so if i have 15 mm rise in 1 metre, i believe i have a gradient of 1.5 % so if i X this by 0.22 i will end up with about 3.3 mm or for practical purposes 3.5 mm. I have attached a small stepping block at one end of 3.5 mm to check things over minutely.What do people think? do you agree with my method and calculations?Rgds Ian
