So, let's keep things simpel and move forward.
I also applied a coat of flat exterior brown paint to the styrofoam and water body to have a basic scenic color to work with. Since Harlem Station was a very muddy and dirty place, that dark brown seems a goof fit. As for Harlem River, I suspect it's water are everything except tropical blue! Can't wait to continue working on the layout! But there's a big challenge as I must build the concrete piers and carfloat apron as quickly as I can if I doesn't want to delay the building process.
