Railways of the Great War (2014)

World War I was a railway war. Michael Portillo finds out how the railways helped to precipitate a mechanised war, shaped how it was fought, conveyed millions to the trenches and bore witness to its end. He takes to historic tracks to rediscover the locomotives and wagons of the war that was supposed to end all war and hears the stories of the gallant men and women who used them in life and in death.
