Micore 300

Steve Rosnick (MR Sept. '94) says this makes the best roadbed; avail. in building supply outlets.

It is used as acoutical panels or bulletin boards and is a byproduct of steel; namely slag.

It's easy to cut, has negligible thermal expansion and grips spikes or track nails. Also, it is self supporting and doesn't need subroaded.

You do need to cut or route the sides for slope and then paint the routed area with latex to seal.

I may consider this for my next indoor 3-rail layout, which I'm now pondering.

I did a little research on this stuff...

It's pretty nasty when it gets opened up...USG makes note not to cut this stuff with anything other than a knife.  Airborn particles are not what you want here.
