One of the most successful designs to emerge from British Railways’ Modernisation Plan was the Sulzer-engined Type 4 1Co-Co1 diesel-electric. 193 of them were built by BR at its own engineering works at Derby and Crewe, and they were collectively known as the ‘Peaks’.
For more than twenty years, these versatile locomotives were synonymous with the Midland main line and the northeast to southwest route. They could be seen from Glasgow and Edinburgh to London, Cardiff and Penzance.
