My biggest layout to date

[TrainNut]

I got even more crazy with the Great Stuff expandable foam and attacked another area on the layout. This time, I wanted to go for a more jagged rock look as opposed to the roundy boulders.
Here, I cut out a huge section of the foam on the front so I could drop the rock cliff way down below table level towards the floor.




...and then sprayed the foam on so it could expand and cure.
