Canadian National Railways. Operations : In an internal Canadian National Railways report, a major function is identified as Operation, Maintenance and Construction: which has to do with all matters relating to the physical operation of the property, such as running of trains, maintaining the property in good condition and the construction of new lines. There appears not to have been an Operations and Maintenance Department as such. These functions were carried out under various incarnations of the Operation and Construction Dept., Operating Dept., etc. and later some? of these functions were continued by the Transportation and Maintenance (1960-). An internal report dated October 16, 1925 states the Vice Presidency of Operation and Construction embraces also Maintenance, and the principal functions of the Department which are termed Sections, each come under the jurisdiction of one of the Chief Staff Officers of the Vice President. Another internal report dated 9 February 1926 states the Operating Department in Canada embraces not only the conduct of transportation, but the design, construction and maintenance of all forms of rolling stock, tracks and structures of every kind, and in a general way exercises direct control over all of the physical property, so that it is necessarily divided up into sections. The fundamental divisions of the Operating Department are 1) operation of trains and conduct of transportation 2) construction, maintenance and operation of track, structures and facilities 3) construction and maintenance of rolling stock, operation of stocks, engine houses, etc. Another internal report, dated June 5, 1946, states the Operation Department is organized on a divisional basis and is headed by the Executive Vice-President. The railway has been divided into geographical units for operating purposes. In Canada, there are three regions, each headed by a Vice-President who reports to the Executive Vice-President. In the United States. The regions are subdivided into districts, each in charge of a general superintendent who reports to the regional Vice-President. The districts are, in turn, divided into divisions. Each division is in charge of a superintendent who is responsible for the actual working forces. The working forces of the operating department are divided into the following categories: administrative, transportation, maintenance and construction. The administrative forces provide the other forces with the means of carrying out their respective functions. RG30 General Inventory.
