A. L. Beattie

From Wikipedia, the free encyclopedia

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.

Early life

[edit]

Born in 1852, his birth was registered in Hunslet as Alfred Luther Betty.[4] He arrived in New Zealand at Port Chalmers in 1876, when he joined NZR.[3] In February 1897, Beattie was given the position of Locomotive Engineer at Addington Workshops in Christchurch.[5] Unlike in some countries, where "locomotive engineer" is the title of regular train drivers, the title in New Zealand then referred to a specific position that oversaw the design and construction of new steam locomotives and the maintenance and enhancement of existing locomotives.

Career as Engineer

[edit]

In April 1900, the Chief Mechanical Engineer, Thomas Forth Rotheram, left NZR to work for the Western Australian Government Railways and was succeeded by Beattie.[6] When Beattie was appointed to the position, the title was "Locomotive Superintendent", but it was restyled as Chief Mechanical Engineer early in his term, between July 1901 and April 1902.[5] During his time in the role, Beattie designed a number of innovative and original locomotives. He retired after holding the position for 13 years and was succeeded by Henry Hughlings Jackson on 13 October 1913.[7]

The Q class

[edit]

Beattie was almost instantly faced with a problem upon appointment as Chief Mechanical Engineer: New Zealand's railway network was expanding, traffic volumes were growing, faster speeds were required, and accordingly, a more powerful type of locomotive was required.[8] Furthermore, although this new class was to haul the heaviest and fastest expresses, it was to burn low grade lignite coal from Canterbury and Otago. Baldwin Locomotive Works recommended a camelback design to solve the problem, but Beattie conceived the idea of an enhanced 4-6-0 UB class locomotive with a two-wheel trailing truck to support a wide Wootten firebox.[9] This created a 4-6-2 wheel arrangement under Whyte notation, and an order was placed with Baldwin for thirteen locomotives to Beattie's specifications in 1901. These locomotives became the Q class, and the first entered service on 24 December 1901[10] after being shipped across the Pacific Ocean. This voyage led to the 4-6-2 arrangement being nicknamed the Pacific type, and it became a popular arrangement worldwide.[8]

The A class

[edit]

Described as the "triumph of Beattie's term in office", the A class was designed in 1905 for service on the Main South Line and the nearly-complete North Island Main Trunk Railway.[11] It was a further development of the Q class and earlier 4-6-0 designs such as the U class, seeking to rectify faults with those designs and improve efficiency and hauling power. Beattie created the initial design before passing it on to Chief Draughtsman G. A. Pearson to complete,[12] and when the first members of the A class entered service in 1906, they were considered to be the country's most handsome locomotives.[13]

The X class

[edit]

After pioneering the Pacific wheel arrangement, Beattie went on to pioneer the 4-8-2 Mountain type. The A class locomotives were not sufficiently powerful to tackle the steep grades on the North Island Main Trunk, and Beattie's solution was the 4-8-2 X class.[14] Designed in 1908 for the opening of the Trunk, the first of eighteen Xs entered service on 9 January 1909,[15] and they were some of the largest and most powerful locomotives in New Zealand.[16]

Other locomotives

[edit]

Beattie introduced a number of other classes during his term, though none so notable as the A, Q and X classes. These included tank locomotives such as 1903's WF class, 1910's WG class, and 1913's WW class.[17] Beattie was also one of, if not the, first to employ the 4-6-4T arrangement – the 1902 conversions of three B class locomotives into the WE class and the WG and WW are some of the earliest examples in the world of the 4-6-4T arrangement.
