Matthew-1286209 Posted February 3, 2023 Share Posted February 3, 2023 I use a riser from/too each level and return back through each level how best to do the return back to the lower levels form the top level?cheers for any help.Thanks MatthewWeymouthDorset Link to comment Share on other sites More sharing options...
96RAF Posted February 3, 2023 Share Posted February 3, 2023 You already answered your own question by saying you use a riser to and from each level, then you ask how to do it. The same way down as you went up. What you don’t say is what the gradient is and what train lengths you hope to transition those level changes.

ModelerXYZ Posted February 3, 2023 Share Posted February 3, 2023 Rising trains from one level to another is not dificult. Keeping them moving and on the track while doing it is. The rule with gradients is simple, make the gradient go as long as possible. The shallower the better. You simply put a board along at the required angle.XYZ Link to comment Share on other sites More sharing options...
LTSR_NSE Posted February 3, 2023 Share Posted February 3, 2023 A picture/sketch of your track plan would help us to assist you.The way you have written your request makes it appear that your track design already allows locomotives to reach each level (both ascending and descending) therefore your request for assistance is unclear.By using the term ‘riser’ do you mean:• a straight (or gently curved) incline, or gradient between the levels.• a helix (or circular spiral) between levels• a lift/elevator between levels (highly unlikely, but covering all bases)If you have used ascending inclines/gradients (to reach the levels above) then you will probably want to use descending inclines/gradients (to reach the levels below).If you have used ascending helix(s), then you will probably wish to use descending helix(s).Finally if you have used a lift/elevator - you could simply run it in reverse!

Weymatt Posted February 5, 2023 Share Posted February 5, 2023 I am using a double track to go up and down via inclines my problem is do I just do a loop joining the up line to return line to go down again? Link to comment Share on other sites More sharing options...
atom3624 Posted February 5, 2023 Share Posted February 5, 2023 How big is the layout?State the obvious, but traction is very limited, so inclines must be as gentle as possible - some quote 4%, some quote 5% absolute maximum without seriously deteriorating the railway effect.Al.

Weymatt Posted February 5, 2023 Share Posted February 5, 2023 My layout is 156" x 108" my inclines go around the periphery so about 500" to raise 10" on each level. so incline about 2.5%.CheersMatthew Link to comment Share on other sites More sharing options...
Weymatt Posted February 5, 2023 Share Posted February 5, 2023 The inclines are strait and curve around the periphery with a rise of about 2.5%.Cheers Matthew Link to comment Share on other sites More sharing options...
96RAF Posted February 5, 2023 Share Posted February 5, 2023 Per cent = per hundred, hence 1 in 100 is 1%, 1 in 50 is 2%, 1 in 200 is 1/2%, etc.Bring curves into the gradient and you effectively increase the angle. Link to comment Share on other sites More sharing options...
Weymatt Posted February 5, 2023 Share Posted February 5, 2023 In can find few layouts using separate tracks to go up and down, most seem to use the same tracks, ie single track this would surly restrict movement with up and down travel. Having to wait for each other to clear the tracks or am I missing something? Link to comment Share on other sites More sharing options...
96RAF Posted February 5, 2023 Share Posted February 5, 2023 No idea, but a picture of the layout plan would help us better understand your concerns. Link to comment Share on other sites More sharing options...
atom3624 Posted February 5, 2023 Share Posted February 5, 2023 Sounds a decent size.10 in 500 = 1 in 50 = 2% - that's reasonable I would have thought.Agreed, curves add another 'drag' aspect.Al. Link to comment Share on other sites More sharing options...

ModelerXYZ Posted February 9, 2023 Share Posted February 9, 2023 Are the 3 pictures each level?XYZ Link to comment Share on other sites More sharing options...
Weymatt Posted February 10, 2023 Share Posted February 10, 2023 Yes thats correct.Middle, Top & Base descending.CheersMatthew Link to comment Share on other sites More sharing options...
ModelerXYZ Posted February 12, 2023 Share Posted February 12, 2023 Are the top and bottom levels over and under the middle level or next to them?This makes a lot of difference with the track geomotry as well as the length needed for inclines.

Weymatt Posted February 12, 2023 Share Posted February 12, 2023 Yes that is correct the risers go on the periphery with a total length is 560" to rise 12" on each layer 2% to 2.5% rise.I hope this makes sense.Many thanks for your interest.Matthew Link to comment Share on other sites More sharing options...
96RAF Posted February 12, 2023 Share Posted February 12, 2023 560/12 is 1 in 26 or around 4%. Link to comment Share on other sites More sharing options...
What About The Bee Posted February 12, 2023 Share Posted February 12, 2023 Hi 96RAFIsn't the incline measured as rise over run? For a rise of 12" over 560", I get 12/560 = 0.0214. Multiply by 100 to get 2.1%Am I doing this wrong?Bee Link to comment Share on other sites More sharing options...
96RAF Posted February 12, 2023 Share Posted February 12, 2023 I wondered about that so I used 12 in 560 = 1.2 in 56 which is steeper than 1 in 50, but not as steep as my original 1 in 26. My big sums days are done I reckon. I use a digital level to check on the board. Mine was 3” in 12’.Edit - oddly my day job used to be calculating angles and levels for airfield arresting gear, so my big sums had to be exact to the mm over many tens of metres.

What About The Bee Posted February 12, 2023 Share Posted February 12, 2023 Arithmetic mistakes can creep into anyone's calculation 96RAF. Especially mine! 🤷♂️ Long ago, I grovelled at the feet of a true genius. The man had 50, count em, 50 US patents. I was one of his reports. He would question every mathematical result I put before him, demanding that I put the numbers (with units) on a piece of paper. This was no use of course, when presented with such a calculation written out, he would say "Those are just numbers on a piece of paper". Quite the character. Hi Matthew 👋. Anyone who can come up with such a complicated layout, over multiple levels, surely does not need to be told how to return to lower levels. The play value will be something only you can answer.If it were me, I'd call the incline the Wapping Tunnel, and have it directly in front the operator. This presents as a "half tunnel" you can see inside, with the cavity lined with the material of your choice. Some lights on the wayside and it becomes an attractive feature, a different perspective. But hey ho, that's just me.Bee Link to comment Share on other sites More sharing options...
Weymatt Posted February 13, 2023 Share Posted February 13, 2023 Hi BeeMaybe should know how to do this but I don't know how to cope with the + and - rails meeting when I connect to the down line I don't see it as a return loop, am I correct in thinking this?I see a single line going up and through each level and getting to the top a return line going back through each level and back to the base via the other rail taking me back down through each level, have missed the point here?CheersMatthew Link to comment Share on other sites More sharing options...
