Hugh Phillips, who runs a family firm in Tredegar, South Wales, is completing a European Community contract to rehabilitate Sudan's once-thriving railways.

With Hugh is his son Adrian, formerly a farmer. The two Welshmen, old and trusted friends of the Sudanese, cope cheerfully with days of sweat and dust and lonely nights in spartan hotels in one of the harshest engineering environments of the world.
