SHS scale Homabed roadbed is for use when connecting our flex track to our sectional track or American Flyer track. It is 3/8" thick, designed to match the rail height of our sectional track when joined with our Flex track sitting on the roadbed. It has a 45 degree bevel to match American Flyer rubber roadbed. The curved sections have slots cut in for easy bending to almost any radius.
Each box of roadbed includes a few sections that are notched to accommodate the locking mechanism on our sectional track.
If you don't need to connect to sectional or AF track, standard S scale Homabed (1/4" thick) is available in a 60 degree bevel at a lower cost.
SHS Homabed is available directly from the manufacturer, California Roadbed Company.
