- I like to use helixes on layouts in small areas to increase both their scenic and operational potential. I have used the same design for five helixes, that I have built across more than twenty years, because it is relatively straightforward to construct. Although other helix designs exist, all designs rely on certain key factors that contribute to reliable running. This video describes those factors and their contribution to reliable running on the Burrawon Branch helix.
Hard to beat that helix construction technique for adjustability and precision. Very well done!
Many thanks. Cheers
Great technique and design. I appreciate the math as well.
Thank you! Cheers!
So much practical information! I especially liked the POV shot through the helix - that really showed things as they ought to be - and I can't think of a better way to understand the subtleties of the technique. Especially interesting was the maths that explains how much the curvature adds to the gradient. Essential viewing for anyone contemplating building a helix.
Thanks for the feedback Derek. I pleased you found it informative. Cheers
love watching trains run in my 3 level helix. I think it just looks cool
I know what you mean. I enjoy it too. Cheers
Thanks for the great tips
It's good to hear you found it informative. Cheers
I have a 4 track n gauge helix with 7 turns 60 metres of track, no issues and never a derailment.
Wow. Congratulations.
Fantastic helix tutorial, and especially important for me as I'm planning my first layout in a small bedroom, and I am hoping that I can create a double deck switching shelf layout, and the helix would also allow a mainline train to run thru a scene as well (-at least that's what I'm hoping).
Question: The 1 in 55 ratio, is that in inches, or cm?
Thanks for the feedback. I'm glad you found it helpful. The 1 in 55 can be in either inches or cm, as long as you are consistent; ie a rise of 1 inch in 55 inches, or 1cm in 55 cm. Remember also that the rise is not a simple vertical measure but is measured in distance travelled. Best wishes with your helix. Cheers
@@burrawonbranchmodelrailway5886 Appreciate the clarification, and well wishes for my future layout.
It looks like your helix was very carefully constructed. I've watched a number of videos on model railroad helixes, and most of them were built sloppily, for example, in one case, to make holes for the threaded rods, the builder just eyeballed a spot and randomly plunged his drill through a thick stack of helix decks (not clamped in any way, and obviously at a slight angle) and I just cringed. The craftsman in me never, ever drills anything by eyeball, and whenever possible, I'll pre-drill any needed holes on a drill press in measured positions before assembly.
Thanks Gary. That's a video I hope never to see. I try to build helixes to the best of my ability because I want them to be trouble-free. As with all benchwork and trackwork, the care and attention taken during helix construction and track-laying is repaid in reliable running across time. It's not hard, and it takes little extra time to plan and construct one well. Cheers
have an idea, thinking how to do, where could i face problems?
make a step by step worksheet, do calculations
finally start building
-REAL ENGINEERING, i'm impressed
-some of the rods seem to be bent; is that just an illusion?
-title reads Burrawon, is it Burrawong, NSW?
Many thanks. The 'bent' rods are an illusion. Burrawon is fictitious. It is inspired by a number of locations across NSW, originally by Oberon and Tarana but is not a replica of either. Cheers
