I thought I'd take a crack at making a few scenic plots for the layout...something in the spirit of those made by Lionel before WWII:
I have a 127 station, one of the smallest Lionel made during the period. I decided I'd try to make a plot to put the station on (something Lionel did not make, although they did manufacture platforms for their larger stations). I cut one in an oval shape, eight inches by sixteen inches, but that looked too small.
Cut out a second base, eight inches by twenty-four inches, then painted it a base "almond" color to simulate concrete:
Then I masked off some sidewalks and hand-painted it a green-base color for the grass areas:
I let that cure for twenty-four hours, then applied the grass material (old-stock Life-Like Landscaping Material, which is close to the dyed saw-dust Lionel used on their plots):
One method to use is to apply the grass material to the wet green paint before it dries, but I have had varying success with that. I instead painted the green areas with a thin coat of Elmers white glue, then dusted it with the grass material, shaking off the excess after a few minutes. After that had dried thoroughly I shot the whole thing with a coat of Testors flat lacquer which should hold everything in place and provide a bit of protection.
I'm going to let this sit for a few days, then start wiring the station and a couple of lamps, maybe add a couple of small trees. We'll see how this turns out.
