  We study the evolution of time-like congruences in the vacuum solutions of
Weyl conformal theory of gravity. Using the Raycaudhuri equation, we show that
for positive values of the coeffcient of the linear term in the solution and in
the absence of the cosmological constant, the incoming rays converge. The
evolution of the congruence for negative values is investigated for different
values of the parameters. The behavior of the congruence under conformal
transformations is also studied.
