Here is a pic of my old layout. A few points:
1) I found I had to use two sets of inclines/risers side by side to get a better setup for scenery. If you only have a narrow area available then one set will work.
2) At the point in time the picture was taken there is no glue nor screws holding the track to the roadbed. Weight and friction were enough. I did ballast the roadbed - the glue used in that process is more than enough to secure the track. There is no need to glue or screw down the track to the roadbed.
3) The roadbed was vinylbed which is no longer made but I've had the same results with their new product and cork.
Hope this helps.
