The most definitive long-form series ever made on the wartime role played by Britain's Home Front Railways. The trilogy combines extensive use of much previously unseen British Transport Films off-cuts alongside cinema newsreels and footage unearthed from the National Archives in the United States. Because the whole trilogy's mostly mute source material has been sound-effected and given a narrative that contextualizes every bit of footage within the very limited budget available to a home entertainment publisher. The titles are 100% original archive material and at 7 hours long in total it is far more detailed than anything ever shown on television. Identifying all the locomotives and locations was painstaking work.
