From the London Telegraph:

By virtue of the foresight, humanity and sheer bloody-mindedness of a young British stockbroking clerk called Nicholas Winton, 669 Jewish children were saved from the clutches of the Nazis.
On Friday, 22 of them were reunited with their 100-year-old saviour – now Sir Nicholas – who has come to be known as the ‘British Schindler’.
A steam engine specially requisitioned to re-enact the last stage of their journey pulled into the very same platform at Liverpool Station in London, where as virtual orphans they had disembarked in 1939.
The emotional ceremony marked what is likely to be the final chapter in the odyssey begun by Sir Nicholas as a 29-year-old.
He was packing to go skiing just before Christmas in 1938 when he received a call from a friend working in a refugee camp in Nazi-occupied Czechoslovakia.
“Cancel your holiday,” said the friend, Martin Blake. “I need you in Prague. Don’t bring your skis.”
The young banker was so moved by what he saw that he immediately set about persuading the British authorities to let in refugee children. The response was sluggish.
But after much work by Winton, a Christian whose family had Jewish roots, the paperwork for each child was painstakingly put in order.
Finally the wheels began to move.
Between March and August 1939 eight trains carried 669 children to Britain, who otherwise would probably have perished in the death camps. Fifteen thousand Czechoslovakian children died in the war.
Sir Nicholas, who was knighted in 2002, stepped off the Peppercorn A1 Pacific class steam engine on Friday morning to loud applause from those he had saved, now grey-haired, and their families.
The train had travelled from Harwich in Essex, containing 22 evacuees about 150 other passengers, on the last leg of the 800 mile journey from Prague.

Not only did he do it, though, but he didn’t need credit. From anyone, it seems:

It was only when he wife Greta unearthed a briefcase in the attic contained lists of the children he saved and letters to the parents did he admit his part.
He said in 1999: “My wife didn’t know about it for 40 years after our marriage, but there are all kinds of things you don’t talk about even with your family.
“Everything that happened before the war actually didn’t feel important in the light of the war itself.”
He also rejected the comparison with Oskar Schindler, who saved about 1,200 Jews in the war, saying unlike the German his actions never put him in danger.
