Based on what I see the vertical distance between the main and the upper section where the water heater would require a helix not a simple grade. It looks to be a foot and a half or more; if it's a foot or 12 inches you'd need (pause to take off shoes and socks) 600 inches, or 50 feet, of 2% grade to make that rise.
yeah i think your right, im in the process of trying to establish a trackplan to fit the helix in , this is probably the hardest thing about model railroading for me(trackplan) i love the hands on side of things ie scenery,benchwork,tracklaying,scratchbuilding all of that but when it comes to working out a plan i get mental blocks trying to make it work how i imagine it
the elevation difference is 14 inches over about 19 ft so i guess i have no choice but helix.i was hoping to have a steady rise up the mountain then a level run back down to the garage door (which would be a run through the top,and side of the mountains) then into a helix to bring it back down to the lower level but i guesshwat your saying is ill need the train to go both up AND down the helix for that much elevation.
on thinking about this perhaps i need to aquire more realestate :thumb: im thinking building another peninsula coming out 90 degrees from the wall in which i could snake the main line in such a way that i could climb the elevation required. perhaps increase the grade to 2.5 % (not sure if thats acceptable)??
hmm not sure i think ill go post in the trackplanning thread this afternoon when i get home and post some more pics and a bench diagram and see if i can get any ideas ill post here when ive done that and if you get any ideas to help be sure to post...
ps hey george ive never been to concerned for building regulations sign1 sign1
