T.A. Walker

Thomas Andrew Walker (15 October 1828 – 25 November 1889) was an English civil engineering contractor.

He worked on major infrastructure projects in the latter half of the 19th century, including the Severn Tunnel and the London District Railway. His final undertaking was the construction of the Manchester Ship Canal.. Walker was engaged as the sole contractor in charge of the construction and he divided the thirty-six-mile route into nine (soon reduced to eight) sections and appointed an engineer to take charge of each. However, he died before the completion of this project. After his death in 1889, Walker's contracts were continued by his Executors and subsequently by the formation of C. H. Walker & Co Ltd. by Thomas's nephew Charles, who was also active in South America.
