Did someone say helix?

I'm going to cheat and buy a kit.

Welcome to the forum!

I need to start a build thread, but the Helix is coming along quite nicely 😎

Looking good, what's the height between levels and what radius did you use?

Space is always going to be a constraint so I had to keep it tight, so Iíve used 1st and 2nd radius set track, so have a diameter of about 600mm with a 45mm lift on each circle.

Iím running analogue for the moment but the loco pulls a rake of six carriages without breaking a sweat so Iím confident that the helix will work for what I need 😁

I'm not 100% sure of the maths but I think a 1st radius at 45mm would put you around 2.5% gradient.

To play it safe I'm going for 2nd degree and <2%, but I want to run loooong freight of 20+ wagons.

Have you tested your carriages on that 1st degree to make sure they're happy and don't kick each other off?
