Good idea. Always good to be inspired by others. Schematic sketch attached. I haven’t drawn the line before. It runs from the house, skirting the patio to the end of the garden. Fruchtecke is behind the greenhouse, Kalkstein in a flower bed on the patio. Storage is down the side of the house In a lean to. Originally I had a 16mm line, 32mm gauge but it was never reliable and was prone to derailments, unreliable live steam and diesels whose batteries went flat at the most inconvenient moment. It was out of use for a few years then LGB dawned. Rebuilt it started off inspired by ÖBB lines but is now largely DR 750mm with some Harz. The continuous run makes all the difference. It was one of the last bits to be added.
