# R. & W. Hawthorn, Leslie and Company

R. & W. Hawthorn, Leslie and Company, Limited, usually referred to as Hawthorn Leslie, was a shipbuilder and locomotive manufacturer. The company was founded on Tyneside in 1886 and ceased building ships in 1982.

## History

The company was formed by the merger of the shipbuilder A. Leslie and Company in Hebburn with the locomotive works of R and W Hawthorn at St. Peter's in Newcastle upon Tyne in 1886. The company displaced its locomotive manufacturing interests in 1937 to Robert Stephenson and Company, which became Robert Stephenson and Hawthorns Ltd.
Perhaps the most famous ship built by the Company was HMS Kelly, launched in 1938 and commanded by Lord Louis Mountbatten. In 1954, the shipbuilding and marine engine activities were put into separate subsidiaries, Hawthorn Leslie (Shipbuilders) Ltd. and Hawthorn Leslie (Engineers) Ltd. In 1968 the Company's shipbuilding interests were merged with that of Swan Hunter and the Vickers Naval Yard to create Swan Hunter & Tyne Shipbuilders.
The company's shipbuilding and marine engineering interests were both nationalised and subsumed with British Shipbuilders in 1977; in 1979 its engine business was merged with George Clark & NEM, which had also been nationalised, to form Clark Hawthorn.
The company's main shipbuilding yard at Hebburn closed in 1982, was sold to Cammell Laird and then acquired by A&P Group in 2001 but now lies derelict. The Company itself, deprived of its main activity, diversified into telephones. In March 1993, Vodafone made a bid for the Company which by then had become a mobile phone air time reseller.
The Hawthorn Leslie building still standing in Hebburn has been the target of numerous arson attacks in recent years. This, combined with the presence of asbestos in the brickwork and the ease of access to children, has led to repeated calls from Hebburn residents and councillors for the building to be demolished.

## Locomotives

After the merger the locomotive side continued manufacturing for main line, light and industrial railways, including a large number built for export, usually to the designs of the Crown Agents.

### Designs
#### Steam

The company manufactured locomotives to order for main line companies. Four 0-4-4T locomotives were supplied to the Metropolitan Railway between 1896 and 1901. In 1915, F. G. Smith of the Highland Railway ordered six 4-6-0s to his own designs. However they were rejected by that railway as being too heavy, they were taken over by the Caledonian Railway. The London and North Eastern Railway ordered a batch of Great Central designed locomotives from the Company in 1925/6.
In addition it built locomotives to its own designs such as a 4-2-2-0 with four cylinders - two inside and two outside - connected separately to the two pairs of driving wheels. It was produced for the Chicago World's Fair of 1893 but could not produce sufficient steam to compete effectively with the American products.
The company later had a number of standard designs including 0-4-0STs and fireless locomotives.
* Two 2-4-0 locomotives were supplied to the Kent and East Sussex Railway in 1899. Owned by the Rother Valley Railway and/or the Kent & East Sussex Light Railway.
| Origin | Wheel arrangement | Class | Notes | Photograph |
| Hawthorn Leslie | 2-4-0T | | No. 1 Tenterden. Works number 2420/1899. Bought new for the opening of the line. Withdrawn for overhaul in 1938, scrapped in 1941. | |
| Hawthorn Leslie | 2-4-0T | | No. 2 Northiam. Works number 2421/1899. Bought new for the opening of the line. Loaned in 1917 to the Weston, Clevedon and Portishead Railway, returned in 1918. Loaned in 1923 to the East Kent Light Railway, returned in 1930. In 1937, Northiam starred in Oh, Mr Porter!, filmed on the Basingstoke and Alton Light Railway. Last ran on 22 August 1938 and scrapped in 1941. | |
* In 1908, an 0-6-0T and two 0-6-2T locomotives were supplied to the Plymouth, Devonport and South Western Junction Railway,
| PD&SWJR no. | Name | LSWR number | Wheel arrangement | Driving wheels | Cylinders | Boiler pressure |
| 3 | A. S. Harris | 756 | 0-6-0T | 3 ft 10 in | 14" x 22" | 170 psi |
| 4 | Earl of Mount Edgcumbe | 757 | 0-6-2T | 4 ft 0 in | 16" x 24" | 170 psi |
| 5 | Lord St Levan | 758 | 0-6-2T | 4 ft 0 in | 16" x 24" | 170 psi |
* Hawthorn Leslie 0-8-0T Built 1906, and became K&ESR, No. 4 and named "Hecate," The locomotive was an outside cylindered 0-8-0 side tank engine with a short wheelbase and flangeless driven wheels to cope with the sharp curves expected on the new line. With 16 in by 24 in cylinders and 4 ft 3 in diameter driving wheels, its tractive effort was 16,385 lb, more than twice that of the line's other locomotives and sufficient to take trains over the 1 in 40 gradients of the North Downs crossing. The engine was painted dark blue and lined in red, with a copper cap to the chimney and a polished brass dome. Eventually, in 1932 they exchanged "Hecate" for an older LSWR "Saddleback" and two spare boilers from the Southern Railway (SR). This was a good bargain on the SR's part, as they repainted "Hecate" (keeping the name), numbered it 949, and sent it to Nine Elms, where it worked almost daily on shunting duties until eventual scrapping in 1950.
* Two Hawthorn Leslie 0-6-2T locomotives were supplied to the Shropshire and Montgomeryshire Railway in 1911. Named Pyramus and Thisbe, these seem not to have been a success, and soon departed, one of them to the Longmoor Military Railway in Hampshire.
* Hawthorn Leslie built 27, A class 0-6-2T steam tank locomotives designed by J. Cameron and introduced to the Taff Vale Railway in 1914.

* Hawthorn Leslie built two 0-6-0T locomotives for the Port of London Authority docks railway in 1922. Works numbers 3529 and 3530.

#### Diesel

Hawthorn Leslie, in collaboration with the English Electric Company, built diesel shunting locomotives for the London, Midland and Scottish Railway in the 1930s. This design formed the basis for the later British Rail Class 08 diesel shunter.

#### Electric

Hawthorn Leslie, and its successor Robert Stephenson and Hawthorns, built four electric locomotives for Kearsley power station between 1928 and 1946 and three of these still exist. No. 2 has been converted to battery operation and is in use at Heysham nuclear power station. Nos. 1 and 3 are preserved, see below.
