Tru-Scale made preformed wood roadbed sections, simulating ballast, that the flextrack would be fastened with tiny steel spikes. These spikes were shaped much like real railroad spikes, and were fitted through holes pre-drilled in the fiber flextrack ties base. An improvement was made when "sectional track" became available in a variety of standardized lengths, such as the ubiquitous straight and curved tracks of , , and radii. These are representative of curves as tight as , which in the real world would only be found on some industrial spurs and light rail systems.
