D326 (later 40 126) was the most famous Class 40, but for unfortunate reasons. The engine had an early chequered history, it was classed as a jinxed loco by some railwaymen, with some drivers being reluctant to drive it. In 1963 it was involved in the infamous "Great Train Robbery", a year later in August 1964 a secondman was electrocuted when washing the windows. Finally, in August 1965, it suffered total brake failure with a maintenance train at Birmingham New Street and hit the rear of a freight train, injuring the guard. It then settled down and had a normal life until it was scrapped in 1984.
