My freelance ho scale layout I am building

[train_guy]

The space and the woodwork look promising. Do you plan to have a layer of blue foam on top for easy trenches etc.?

Is the blue foam easier to contour,then say the pink foam?I'm glad you mentioned that,cause when i start building,i'd like to know which is more suitable.I'm a fan of Pelle K Soeborg's scenery techniques,and he uses alot of foam on his layout.His techniques are second to none.
