Alfred Luther Beattie JP (1852 – 2 May 1920),[1] typically referred to as A. L. Beattie,[2] was a pioneering locomotive engineer. Born in Yorkshire, England,[3] he gained fame as the Chief Mechanical Engineer of the New Zealand Railways Department (NZR) between 1900 and 1913. During this time, Beattie designed the Q class, the first 4-6-2 (Pacific) steam locomotive class in the world, and he was also one of the earliest people to use other wheel arrangements.
