Class 40
Two hundred diesels that English Electric built in 1958-62, among the first big main-line diesels of BR's Modernisation Plan. They took over top expresses on the East Coast and West Coast Main Lines and from Liverpool Street, at up to 90 mph (145 km/h), on long eight-axle bogies with an unpowered pony axle at each end. Faster locomotives and electrification moved them to secondary passenger and freight work in the north of England and Scotland. The first 125 had headcode discs on the nose, as drawn here; later ones had split or central headcode boxes.
