The Bombardier HR-412, also known as the MLW HR-412, was a 4 axle, 2,400 horsepower (1.8 MW) freight locomotive manufactured in Montreal, Quebec, Canada. Ten were built for Canadian National Railway in between September and November 1981, numbered 2580–2589, and one was built for Bombardier as a demonstrator in May 1982, numbered BBD 7000. BBD 7000 was later sold to Canadian National.[1]

The model designation stood for HR - High Reliability, 412 - 4 axles, 12 cylinder engine. The HR-412 was designed as the successor to the MLW M-420.
