Describe the Suggestion

First, I would like to say y'all have done an amazing job with this mod. There simply isn't another like it. Machines you can actually SEE working and not just a box with a light. Please keep to the original scheme of non RF/electrical powered items, it's what sets this mod apart from every other mod out there.

My question/suggestion is this:

Is it possible to smooth the curves on inclines to make a more visually appealing layout? I'll include a screenshot of my attempt at a spiraled decent into a cave (well I was testing above ground, but my intended base would be in a cave).

The idea was to have a train go from farms, etc. above ground and then spiral down into my base. With the mechanics as is, it requires a flat section to connect curves on a slope which results in more of an down, flat, down, flat and not at all smooth spiral.

I understand if this is not at all possible to do giving that it is Minecraft and certain rules/conditions have to maintained and respected but was hoping maybe you could try (if you haven't already).
