Mixed up a few batches of fresh, crunchy ballast and set them out to dry over the weekend.
Almost 2 gallons made. Enough to keep me busy for a while.
During that time I endeavored to clear away enough space in this corner so work could continue. Then the beginnings of a stone arch bridge were made of hardboard. Here's the second try, using smaller arches, as the first cutout made the bridge overpower the confined space.
On a slightly different angle the roadbed looks more interesting. A huge adaptation to the bridge to accommodate that lower single track will be tricky but I have a plan.
