Concrete Streets with Railroad Right-of-Way running through

I used "1/32 task board" to create my concrete panels for the streets. I used tacky glue to hold down the task board. It was preprinted with 4 different shades of gray, tan and olive green spray paints. Next, I will draw on "cracks" in the concrete with a very fine sharpie marker and some chalks and vehicle oil stains added to the streets.
