It took until 1962 to get things on the right tracks. That year, working closely with BR's generally excellent Design Panel, the Falcon Works of Brush Traction at Loughborough built the first of what was to be the 512-strong Brush Type 4, or (from the early 1970s) Class 47 diesel-electric. A smoothly handsome machine, this new six-axle, 2,750hp, 95mph diesel-electric was a railway operator's dream. It could rush heavy express trains along at cracking speed uphill and down vale; it could pull long freight trains speedily and well. It was easy on maintenance, liked by crews, and, importantly, here was an all-purpose British diesel that looked truly, and gracefully modern without trying too hard, and owing nothing, in appearance, to US design practice.
