Greetings to the board (Newbie/Beginner level enthusiast here),

I brought a 4-6-0/45mm Wonderland Flyer G-Scale last year (similar model- http://www.youtube.com/watch?v=d6eP9tWMfy4) and would like to try some innovative layout ideas but not sure how to go about planning it, materials/extra track needed etc...

I have perused some of the software talked about on these forums (Anyrail, XTrackCAD, Atlas - Righttrack, etc...) but have yet to see anything geared to the Bachmann E-Z track specs. Are there compatible lines that I am overlooking or is it simply G-scale is as G-Scale does?  I came across this sturdy looking no frills converter: http://webpages.charter.net/dobbsp/mrr.htm. Not sure if I would be able to make a layout in another scale and simply transfer but by all means enlighten me if so. 

My basic idea is: I would like to take a generic oval and build a graduated trestle and loop back down under it in sort of a single helix structure. I feel as though I could probably do it on the fly but i'd prefer not to make the common amatuer mistake of reinventing the wheel if possible.

Any suggestions or resources would be most appreciated.
