Thanks for posting the sketch, Max. That's a very interesting layout. I like the idea of the smaller loop inside of the larger. I'm working on a layout design now and was trying to design a large loop for some of my locos that require a ten foot radius and still have some interesting track work for the smaller locos. You have some good ideas there. Thanks.
As I have a smallish garden working area, max' 25' wide x 14' deep. It was always the intertion to have a figure 8 layout to get the maximum run length. But, I didn't want the hassle of the earthworks for a flying junction and its limitations for operational purposes, hence the crossing on the flat. Creating 2 separate loops was a small jump from that just requiring the (econimical) curved point and an extra regular switch to make it work in a smallish area.
The turning Y adds a little more fun. It is contolled by a manually operated reverse polarity switch when running track powered loco's.
The line runs into the house where the steam up area is on the back wall of the living room ! A very wellcome feature to some members of my local area 16mm group. There is a height disparity from the garden to the house floor height of 2'6", it just had to be taken advantage of.
Having the loops one inside the other allows for some planting opportunities that create a visual separation between the two ruunning lines. One can have fun making things dissapear and reappear from different viewing angles.
I run a Bachmann K-27 on the full figure 8 of this line, not tried one of them over the inner radius of that curved point yet. As I said the plan is not to scale, despite appearances I try to keep the turn radii to a min' of 4', but mostly at 6'.
I'd be interested to see what you decide on.
