Power to Stop 1979 Directed by Bill Mason
The majority of railway vehicles are fitted with cast iron brake blocks which, although relatively cheap to produce, wear rapidly in service and need frequent replacement. The film shows how an investigation into some of the problems associated with these blocks led to the development of a new type with a higher phosphorus content which gives better performance and has a longer life.
