Mersey Docks and Harbour Company
The Mersey Docks and Harbour Company (MDHC) is the current incarnation of the Mersey Docks and Harbour Board which itself had replaced Liverpool Dock Trustees who had run the docks since 1780.
At one point the Mersey Docks and Harbour Company railway totalled 104 miles (166 km) of line, with connections to many other railways. A section of the line ran, unsegregated from other road traffic, along the dock road. Today only the Canada Dock Branch is used. It also operated large quarries at Creetown 
The MDHC was accused of "Macho Management" by the Financial Times regarding its treatment of some its staff, which resulted in Liverpool Dockers' Strike. In recent years the safety record of the MDHC has worsened.
