  It is shown that if two Reissner-Nordstr\"{o}m space-times, both with the
same mass m and charge e, glued together in the singularities, then the light
ray in black hole of the first space-time can go continuously through the
singularity into black hole of the second. The behavior of tidal forces near
the Reissner-Nordstr\"{o}m space-time singularity is examined by considering
what happens between two particles falling freely towards the singularity.
