 At the 1926 Imperial Conference in London, some degree of control over the railway was granted to Southern Rhodesia.There was also the issue of attracting labour for mines and farms from the far north and this gave impetus to Coghlan's and Moffat's territorial expansionism in Northern Rhodesia and Nyasaland.Coghlan called on Britain's Colonial Secretary, Leopold Amery, to give the North entirely to the South or at least the reversionary right to it but Amery refused this request.
