  A new hyperelliptic solution class for the hyperbolic Ernst equation is
obtained by transforming the regarding solution of the elliptic Ernst equation.
Furthermore, a nontrivial way for obtaining general polarized colliding wave
solutions from this hyperelliptic family of solutions is presented. The
explicit form of the solutions for a Riemann surface of genus n=1 is given. In
addition, an explicit example in terms of a Khan-Penrose seed is provided,
emphasizing the importance of the presented procedure for generating general
polarized colliding plane-wave space times from space-times with a collinear
polarization of the colliding waves.
