New chairman Peter Parker addresses British Rail staff - it may sound dull but it's intensely compelling. True, compared to the many gorgeously lush documentaries that British Transport Films made, this is no-frills un-cinematic stuff. But Parker is a truly gifted screen communicator: his frank, incisive intelligence, and his own belief in a future for rail, practically leap off the screen.
A kind of 'state of the nation' message to a huge (and far from untroubled) workforce, the film is such gripping viewing partly because it places us deep inside the world of mid-1970s British Rail, behind the scenes - beyond public view and unfiltered by external spin. Though Parker is speaking about a vanished world - its economy, technology and industrial relations all so unlike our own - an incredible amount of his analysis is resonant today.
