The Modernisation Plan was a hugely costly failure for BR. The total cost was greater than the estimate, eventually exceeding £1.6 billion (£33 billion in 2020), while the railways' financial losses (between £102 million and £68 million per year throughout the 1960s) increased as traffic volumes and market share continued to decline. While some of the new locomotives and rolling stock procured under the Plan were successful and would go on to have very long service lives, many proved to be embarrassing (and high-profile) failures. The modernisation of BR's freight-handling facilities was ineffective and even before the Plan was officially concluded, many of the large yards built a few years previously were mostly empty.
