Abstract
We analyse vacuum gravitational "soliton" solutions with real poles in the cosmological context. It is well known that these solutions contain singula rities on certain null hypersurfaces. Using a Kasner seed solution, we demo nstrate that these may contain thin sheets of null matter or may be simple coordinate singularities, and we describe a number of possible extensions t hrough them.
