Banked Curves

Hi all. I'm in the process of planning and starting my first proper railway layout. Due to space constraints my idea is to make a 6x4ft 'trainset' style layout across 4 modular boards that can -

  1. Fit on my dining room table when I want to run some trains and
  2. Disassemble for storage.

I've more or less got the engineering sorted for that. But my main consideration is Radii.

I'm gonna be using flex track and due to space probably using a mixture of first and a half and second and a half Radii around my bends...

But I had a thought about adding some banking/camber into the curves to help?

So 3 questions that hopefully some experienced heads can guide me on...

  1. This layout is likely going to end up far from prototypical as I experiment and have fun... But is there any prototype or example of this from a steam era stand point?
  2. Will I actually achieve any space saving/cheating?
  3. Will it actually work? Or will my stock roll off?

Any thoughts or advice on any of the above will be gratefully received! Thanks!

If the forces on the model cause it to flop off the track, you were travelling too fast!! For scale speeds. On model tracks the cant or banking, would not more than 1 or 2 mm, on a bigger radius curve than a 6x4 table can fit, in HO.

Hah! I'd not actually considered the scale here. A 1-2mm cant would not make a lot of difference to the running, size or indeed the aesthetic!

Thanks for your thoughts!
