ok I proved to myself again the lack of my layout planning/building experience I was able to put up another stumbling block for myself. Major error in track heights and keeping grades to less than 3% while having providing some room for buildings. It started with setting track height's for each side of the lift bridge. On scarm I wound up setting them at 4" mainly to not have to deal with bridge lifting clearances. All seemed to be ok, until I started printing the trestles for the incline. Not enough length to accommodate a 3% grade. In this instance I was contemplating a ECO for the bridge lift design and reprinting the parts. I did decide to leave the bridge alone and lengthen the grade to accommodate the 3% grade. So added a 37" section which helped with it being put between two 072 curves, making it appear a smoother transition. It breaks up the main street town, although I think it adds more town detail/features/possibilities. So now a little adjustment to trestle heights and I will be back to printing trestle pieces. Here is a pic of the new section with some trestle pieces placed for fit. The foreground track on white trestle is the revised section. Behind that is the other mainline which is starting to incline to ultimately go over mainline2 tracks. Behind that is a spur on a trestle that will be used for delivering coal to a distribution center. From what I have found reading many posts, I need minimum 5.75" clearance when one track goes over another. PLEASE if this is incorrect let me know and also is there a height that is generally agreed upon or most commonly used? Last pic shows the tracks that will be over and under each other. This is where I would like to confirm heights. Thanks all for looking and helping!
