I keep reading about products like Masonite. I have gone to 3/4" pink insulation board. There hardest part of using this is cutting the angle for inclines. If you are going any distance without support under it, it will sag and can break if you lean on it. I do not have long distances and where I might I am using 2" wall insulation. I glue the pieces together and while the glue is wet bend to shape and use clamps to hold together and nails or screws to hold the curve until dry. So far this is working well. I do use 3 or 4 pieces together depending on span and number of tracks (N-Scale).
I was looking for something as light weight as possible where I did not need a saw. I am also designing and building the layout to break apart for moving in the future. The layout is currently split into 2 - 4x4 and 1 - 3x4 sections with rail joints at the section separation points. I need to do this because I did not want to a=have to destroy the layout once I move in the future and I will be moving. The layout in on 2" foam board glued to wood frames that have dowels that hold the entire layout on a table.
