Each company was to provide an equal amount of capital and four representatives to the joint management committee. This arrangement was confirmed by the Great Northern (Cheshire Lines) Act in Parliament in 1863; this was the first official use of "Cheshire Lines" and at the time it was entirely appropriate as the majority of the lines involved were in Cheshire. This Act had not, however, formally set up a separate legal body, providing instead for the two companies to manage and work the four railways through their existing structures.
