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.

The City of Sheffield is renewing itself, but until recently Sheffield's railway network exemplified the confusion and inefficiency created by competitive railway expansion in Victorian times. Now British Railways has swept away the small depots and the conflicting lines, and has centralised its goods operations in a new Freight Terminal, a Diesel Maintenance Depot, and one of the most modern Marshalling Yards in Europe, thus providing freight services fit for Sheffield's needs.
