I am researching the routes of the Cairo-Cape railways as part of my PhD. Tanzania's Central Line, from Dar es Salaam to Dodoma, was built by the Germans and there seems to be little about it in English. I am looking for historical sources on its building, anecdotal material and material about its impact on the local people, together with its importance in the German colonial endeavour. Unfortunately, I don't speak German, but may be able to get help translating short references. Thanks for your help.
