Re: Upper level track
About 30 feet and that would be steep!!! You need a spiral for that sort of height! The steepest UK main line gradient relying purely on adhesion is the Licky Incline at 1 : 37.7. Models can usually manage steeper but not over such a long length. For a couple of inches for a coal drop 1 : 20 might be ok but even that would need three and a half feet.
Growing old, can't avoid it. Growing up, forget it!

I considered this for an under level storage area. Using Anyrail and a maximum 2.5% gradient, it calculated Id need an almost full circuit of my 5m x 2.6m layout to drop to 12 to 18 inches. I had to discard the idea. Even a helix was too big imho so just devised a storage area on the main layout.Spo wrote:What length of track would I need to rise to an upper level 12 inches above

I am afraid this is akin to asking 'will I enjoy a meal containing tofu?. We just don't know enough to provide sensible advice.Spo wrote:What length of track would I need to rise to an upper level 12 inches above
Answers to many questions such as these below will help:
What scale or gauge?
What type of track?
Minimum curve radius on gradient?
What type of traction? rigid powered chassis on a, steam loco, or tender, or one bogie; or twin bogie with both powered, or steam loco and tender both powered?
Steam loco wheel arrangement?
Weight of traction?
Metal driven wheel traction only, or with traction tyres?
Would you install a magnet system and/or weight on the loco for extra traction?
Would you if necessary significantly modify the model(s)?
Maximum length and weight of planned train?
Assessment of free-rolling capability of unpowered wheels?
Is a restart required from rest with the whole train on the steepest gradient, including the most severe curve?
Re: Upper level track
I reduced the gradients/distance on the BNR by having one track ascending and the other descending, although that does make the baseboards more complex.
