Hey everybody—welcome back into Old Mountain Bricks. In this LEGO City update, I finally start tackling the long-planned nature area and campground, and that means making some big layout changes. The first (painful) move was saying goodbye to my favorite little S-curve “snake” and rerouting the train into a tighter oval by Town Hall. I ran the train one last time for the ceremonial farewell, then tore out a ton of track so I can actually work in this section and save the extra pieces for a future expansion later this year. Once the track was moved, the real puzzle became baseplates and alignment. I pulled out the old gray track plates, realized I needed more baseplates, and talked through why I stick with official LEGO baseplates—those tiny measurement differences add up across a whole city. From there, I mapped out the vision: a mountain that forms a triangle-ish shape, a train tunnel, and possibly a road tunnel crossing through the same structure (dangerous… but it’s LEGO, they’ll be all right). I also blocked the idea out with loose rock panels and blue tiles to visualize a creek/river and waterfall, then started thinking about elevation, forced perspective, and sets like the A-Frame Cabin and the LEGO Ideas Treehouse for the back of the wilderness area.
