I did a 24" radius helix five tiers high and it worked good with 4 powered units pulling a 30 car freight. I now prefer much larger curves (less drag=longer trains) and would build 32" to 48" radius if I were building another one. Allow at least 2" each side of the centerline (3" is better). Swing all 3 lines on 1/2 to 3/4" plywood and cut out the curve with a saber saw. It goes pretty fast. Cut the splice plates about 8 to 9" and glue under the plywood. It is easier to do one full layer at a time with cork and track leaving enough short or loose to overlap the next section joint. Make your track work flawless as you go and always stagger joints to avoid humps and kinks. One thing to really consider is doing the helix double track as there is a lot of hidden track and you can use it to stage trains in each direction. Make the outer track the upward direction as the grade will be a little bit easier with more radius. Think it through and do one step at a time. It sounds scary but really is doable and it's neat the first trip to see what you have accomplished.
