I'm guessing they're just Kato's version of insulated rail joiners. If so, they're used to electrically isolate sections of track. You'd want to to this, for instance, to a siding so you could park one locomotive and then operate another. Some track formations, like reversing loops and turning wyes, require that they be used to prevent short circuits.

I'm not familar with the layout you mentioned. If you post a track diagram or a description, maybe we can figure out if you need them.
