Train set

I’m good at a few things. I take decent, sometimes great photos (when I’m not too lazy to pick up the real camera), I can cook ok, I think I’m a potentially good writer, and my students appreciate me. But It appears I’m not good with train tracks. I’ve been trying off and on for about 10 days to make a circuit that will not cause derailment and that will fit in our limited space. I thought doing it under the tree would be perfect. Not so much. Oli was still happy to play with today’s efforts. But I’m getting a bit annoyed!
