Trafford Park is almost entirely surrounded by water; the Bridgewater Canal forms its southeastern and southwestern boundaries, and the Manchester Ship Canal, which opened in 1894, its northeastern and northwestern. Hooley's plan was to develop the Ship Canal frontage, but the canal was slow to generate the predicted volume of traffic, so in the early days the park was largely used for leisure activities such as golf, polo and boating. British Westinghouse was the first major company to move in, and by 1903 it was employing about half of the 12,000 workers then employed in the park, which became one of the most important engineering facilities in Britain.
