Abstract
Recently Bernd Schmidt has given three explicit examples of spacetimes with toroidal null infinities. In this paper all solutions with a tor oidal null infinity within Schmidt's metric ansatz (polarized Gowdy mo dels) are constructed. The members of the family are determined by two smooth functions of one variable. For the unpolarized Gowdy models th e same kind of analysis carries through.
