Thanks for the imput .
We have just moved to our new home(on acreage) so I have somewhat of a clean slate to work with. I already have the sections of "test track"(fixed track) ready to lay, this is apx 30+ mts of straight with a reversing loop. Part of the straight butts up along the side of the front concrete apron of our industrial shed(workshop), this will allow easy movement of r/stock between shed and line. All of this I want to cover with grass except for the actual points as it is a high traffic area
From the "shed line" I intend to run the line across the gravel drive as part of the cattle grid, then following the fence to what will end up as the "formal garden". here the line will loop back to itself, total length of this section is around 300-350 mts. like your self this formal garden section is under trees so at the moment the ground is a bare compacted wasteland. our intention is to build edged & raised garden beds with shade tolerant grass in-between. In these grass corridors is where the "buried track will also be. The only hazard to the track would be from the ride-on, mine you the one we have has a low ground impact as we have some very soft areas elsewhere on the block.
I would have liked the track to run the outer edge of the House block but there are areas that a live steam track just can't be laid, the rest of the acreage has some sort of livestock on it so that is out also.
At the other end of the test track I will be able to attach "Portable" sections(same as cane track) when friends come around, unfourntuatly these sections wont be able to join up to the garden section due to the excessive slope of the house block and part of that loop would also pass through a large section that gets covered in water every times it rains, even in the dry your foot sinks in.
