G scale garden railroad

G scale model railroad I built for a customee in 2016. I had much help with a good friend of mine to complete this.
it's a simple loop with passing sidings with DC remote control. it is built on pvc pipe stilts with plastic boards for the road bed. the layout is on a hillside with landscaping filling in the grade around it. we brought in 2 truck loafs of clay to fill around it. it's a constant battle of erosion but has been running well for 8 years.
