R. & W. Hawthorn, Leslie and Company

[4] The company's main shipbuilding yard at Hebburn closed in 1982,[6] was sold to Cammell Laird[7] and then acquired by A&P Group in 2001[8] but now lies derelict.

The Hawthorn Leslie building still standing in Hebburn has been the target of numerous arson attacks in recent years.

[11] 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.

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.

The London and North Eastern Railway ordered a batch of Great Central designed locomotives from the Company in 1925/6.

Hawthorn Leslie, in collaboration with the English Electric Company, built diesel shunting locomotives for the London, Midland and Scottish Railway in the 1930s.
