I. An _Assistant-Director of Railways_ for Cape Colony, who was on the staff both of the Director of Railways and on that of the General Officer Commanding Lines of Communication, Cape Colony. His business it was to co-operate with the General Traffic Manager of the Cape Government Railway, in whose office he was given accommodation. In this dual capacity it was his duty to inform both the General Officer Commanding and the Director as to the traffic capacities of the railways; to take the orders of the G.O.C. while advising him as to the best method of carrying them out; to inform the railway officials what was required, and, Sir Percy adds, in giving these details, "to protect them from interference by unauthorised military officers." It was the duty, also, of the Assistant-Director to see that proper regulations were issued to the Army for (_a_) the efficient conduct of entrainments and detrainments; (_b_) the forwarding of stores, and (_c_) the keeping of financial accounts in respect to the use made of the lines for military purposes. As between the General Officer Commanding and the Chief Traffic Manager, the Assistant-Director of Railways was the sole channel of communication. II. Four _Deputy-Assistant-Directors_, undertaking similar duties over particular sections of the railway system. III. _Railway Staff Officers_, located at leading stations to superintend all important movements, and constituting the only means of communication between the Army and the stationmasters. The latter were to take orders in respect to military requirements from no one else, and were, in turn, to be protected by the railway staff officers from interference with by other officers having no authority to give them direct orders. The defective step in the scheme, as originally planned, was in respect to the railway staff officers, who, of all those constituting the Military Railway Controlling Staff, were, under Army Regulations, on the staff of officers commanding lines of communication and thus not controlled by the Director of Railways. The officers in question, though charged with the duty of looking after entrainments, detrainments, etc., were in no way to interfere with the railway staff in the shunting or marshalling of trains or in regard to the traffic arrangements generally. For this reason the framers of the Army Regulations had assumed that there was no need for the railway staff officers to have any knowledge of railway operation, or to be under the control of others who did possess such knowledge.
