Homasote spline roadbed was used on the original V&O and was described in

the late 1970s RMC series.

Happy New Year.

What I have done before on a layout and will do on parts of the new layout will be to take two pine strips about 1 1/4 by 3/16 or so (you can buy them as latice strips at the store or make your own from clear pine if you can resaw wood). I put a riser of about 3/4" sq up from the bench work every 3 feet or so (more on curves) and then I fasten a spine to each side (with glue and screws) I also put a spacer every foot or so (just a 3/4" sq block). Let this all dry, sand the top to make sure it is level (or a little supper elevated in curves) and glue on a piece of homosote on top to the track. Screw down the homosote every so often to the spacers and or the risers. Works like a charm. Last time I did this it was up for years with out any give at all, in a fairly damp (in the summer) basement. This time I will have to use some sort of spacer and two risers as I have a double track mainline.
