In a previous paper (Paper I), several superposed Weyl solutions of Einstein equations were investigated that might have some astrophysical relevance. We drew the gravitational field lines in the superposed space–times and the distortions of the Schwarzschild event horizon induced by the additional matter. Here we are concerned with the motion of free test particles in the same fields. In particular, the influence of the parameters (mass and location) of the additional sources on the positions of important circular equatorial geodesics is studied.
