two short pieces of O gauge model train "roadbed"

These are probably short sections of track either made or just used to display model train cars. Wooden bases hold the track itself, but there aren't any obvious provisions for connecting the ends to something else, thus my guess that they're 'cut-offs' from longer sections that happened to still be usable alone. The track gauge is the same, one is slightly longer and unmarked, the other is stamped "TRUSCALE ROADBED PAT PEND OCASU" on its bottom.
