I can't remember where I found it but there was a set of web pages that described how someone built a garden railroad on benches that for the most part ran around the perimeter of the yard. I think it was located somewhere in the West.
My current design has a siding and station area that is approximately 6 feet wide by 20 feel long. I think I want to put this on a bench or frame so that the whole section is reasonably level. I will probably build this first since it will dictate how the rest of the layout fits in the yard. The supporting structure needs to be strong enough to be able to climb across it if necessary. I am trying to figure out what is the best way to design it so that it drains but can have appropriate gravel fill and possibly some plants between the tracks so that it looks realistic.
The siding area, except for the turnouts, will be straight track. Is having 6" on center track too close together? What scales will work (my personal equipment is going to be 1:32 but I figure I may need to be able to run guest's equipment which will probably be 1:29).
I am also agonizing over how high to build the railroad. At 1 foot, I can probably back fill it with dirt. At 2 feet it is going to be predominantly on benches, possibly with some back fill. Regardless of the height, I want some live plants growing within the layout.
I have decided, at least initially, that the bulk of the rail bed is going to be on 2X6 boards. This gives me an easy way to level the layout, is relatively inexpensive, and I can easily change my mind after I look at what I have built.
Any recommendations?
