HS4000 Kestrel was a prototype high-powered mainline diesel locomotive that was built in 1967 by Brush Traction, Loughborough, as a technology demonstrator for potential future British Rail and export orders. The locomotive number is a combination of the initials of Hawker Siddeley and the power rating of its Sulzer diesel engine (4,000 hp), making it the most powerful locomotive built by the company.
