  We revisit the Taub-NUT solution of the Einstein equations without time
periodicity condition, showing that the Misner string is still fully
transparent for geodesics. In this case, analytic continuation can be carried
out through both horizons leading to a Hausdorff spacetime without a central
singularity, and thus geodesically complete. Furthermore, we show that, in
spite of the presence of a region containing closed time-like curves, there are
no closed causal {\em geodesics}. Thus, some longstanding obstructions to
accept the Taub-NUT solution as physically relevant are removed.
