asked the Secretary of State for the Colonies what surveys have been made for railway development to link Broken Hill, in Northern Rhodesia, to the East African system, and to the ports of Mtwara and Dar-es-Salaam in Tanganyika: and whether the results were favourable for such development.

Separate engineering and economic surveys are being made of the possible railway links between the two systems and reports are expected in about six months' time. Results cannot be assessed, or decisions taken, until these reports are available.
