Nicholas Winton, a young English stockbroker, saved hundreds of Czech children from the hands of the Nazis as they bore down on central Europe in the late 1930s.
By organising their evacuation on eight trains from Prague to London before the borders were closed at the start of the World War II, more than 600 mainly Jewish children reached the safety of Britain.
This week a special commemorative journey of a Winton Train is retracing its original route across Europe. On board will be many of the now grown-up children who escaped from Prague.
Robert Hall went to meet him.
