1 For a century between 1850 and 1950 railways exerted a profound influence upon the development of Canadian society. While considerable attention has been given to the impact that railway companies had upon Canada's geographic growth both as the instruments and instigators of Canada's own version of manifest destiny, their role as instruments of social and technological change has received comparatively little attention. Unlike other countries where the analysis of "the railroad" has led to an examination of its impact upon urban growth, social attitudes and popular culture in its broadest sense, Canadians for the most part continue to examine the legacy of our railways from a very two dimensional perspective.1 In many respects, this approach would be analogous to examining the impact of the Catholic Church on Canadian society by studying the growth in the number of parishes, annual revenues from the collection plate, and an occasional analysis of changes in the Church hierarchy over time.
2 There have been exceptions to the rule. In the 1980s, Craven and Traves produced a superb analysis of the early role of the Grand Trunk Railway as an important industrial force in nineteenth-century Canada. To their apparent surprise, both scholars found that railways were early incubators of industrial practice in Canada. The substantial shops founded by the railways in such cities as Montreal, Hamilton, and Stratford produced a wide range of products that increased the authors' appreciation of the railways' important role as industrial innovators in the nineteenth century. This was an important study in that it was one of the first attempts the author is aware of where academic historians sought to analyse the impact of railways and railway technology upon Canadian society in a context other than that of a transportation system.2
3 Similarly, Harold Kalman and Douglas Richardson underscored the importance of the railways' influence on the built environment in a short overview of transportation architecture in Canada. Citing examples of bridges, stations, and major hotels constructed in the nineteenth and early twentieth centuries, the authors sought to draw attention to "the railways' architects who pointed the way to a public architecture that raised our self-awareness and that was to be promulgated as a national style for all of Canada."3 The architectural legacy of Canadian railways has undergone considerably more scrutiny than other aspects of its broader cultural influence, yet even architectural historians continue to view the railway structures in isolation. To whit railway stations, even hotels, are studied often as individual entities and not as part of an integrated system of related structures. It was the successful integration of these individual parts that initially set the railway apart from other transportation modes and corporations.4
4 Their primary purpose of moving goods and people along their lines meant that railway technology required the development of a highly integrated and innovative corporate structure. As Alfred Chandler stated, "no other business enterprise, or for that matter few other non-business enterprises, has ever required the co-ordination and control of so many different types of units carrying out so great a variety of tasks." In the Canadian context this structure was not only vertically but also horizontally integrated to a degree unmatched by many other railway enterprises on the globe. While many individuals pay lip service to the importance of railways in the development of Canada, they do so while failing to grasp how pervasive a role railways played within Canadian society as employers, suppliers, clients, patrons, educators and facilitators. Because of the truly national scope of their operations and their highly integrated and complex structures, our railways' interests and impact extended well beyond their rights-of-way.5
5 This very point was brought home following the recent donation of the Canadian National Railway Company's photograph collection to the Canada Science and Technology Museum. Comprising over 750 000 images and covering the period from the mid-1850s to 1985, the collection provides ample evidence of the diverse interests of Canadian National, its predecessor railways, and its subsidiaries across Canada. Ironically, when publicizing a significant donation from one of Canada's major railways, the Museum found it necessary to emphasize that the photograph collection contained more than just photos of trains. In fact, the donation corresponds exceptionally well with the Museum's own mandate in the breadth of subject areas covered and its truly national scope.
6 As a product of the industrial revolution and a pattern for the modern corporation, railways characteristically embraced technological and scientific innovations in order to facilitate operations and maximize profits. This preoccupation with technical innovation and an associated fascination with things modern is documented consistently in many of the choice of topics. The CN photograph collection provides a telling portrait of technological change in Canada over time. In the communications field the transition from telegraphy, to telephone, to increasingly sophisticated forms of radio transmission for both private and public use is but one area where the photograph collection provides researchers with a valuable source of informative imagery. This pattern is repeated in a wide variety of fields that emphasize Canadian National's abiding interest in agricultural development, natural resource extraction and processing, manufacturing, marine services, communications, aviation, and, of course, railway operations.
7 As a research resource, the collection offers more than just a large volume of potential illustrations. Rather, the often detailed view of installations, equipment, or operations may function as primary documents that permit a closer study of an object or process in its original context. Many of the photographs were taken to illustrate or document a specific process or technology, with sequential images providing highly informative step-by-step descriptions that are not necessarily available, or not well understood, when presented in written form.
8 For all of its value in recording technological change, the collection illustrates the social context within which new technologies functioned. The human element, sometimes lost in the discussion of technological change, is a notable factor in a great majority of the images. Whether it is the assembly line worker manufacturing aircraft or a posed photograph showing people attentively listening to a radio broadcast aboard a train, people reacting with new technology is a recurrent theme that helps to define the collection. This was by no means accidental and probably reflects the promotional use intended for many of the images.
9 Even a cursory examination of the CN photograph collection quickly immerses the researcher in a historical resource that provides a rich, albeit not impartial, overview of the railway's far ranging activities and interests. This unique collection documents the transformation of Canada and Canadian society through its often detailed portraits of cities and regions from coast to coast. This portrait of a changing society is all the more powerful because of the rich variety of the subject matter covered and the railway company's persistent fascination with recording the use of new technology and documenting modern Canadian life. Ultimately it is a record of technology that is national in scope and surprisingly human in character.
