It is proved that there exists a left determined model structure of weak transition systems with respect to the class of monomor-phisms and that it restricts to left determined model structures on cubi-cal and regular transition systems. Then it is proved that, in these three model structures, for any higher dimensional transition system containing at least one transition, the fibrant replacement contains a transition between each pair of states. This means that the fibrant replacement functor
