The first step in the progressive policy of railway building in which Chile has been engaged in recent years, was the construction of the Transandine Railway via Uspillata Pass. This important line, connecting the Atlantic with the Pacific, and giving to the Republic rail connections with countries to the east of the Andean range, brought the importance of better interior transportation facilities more closely to the minds of the people, and the result has been a period of railway building surpassing the expectation of the most radical advocates of an aggressive industrial policy. The history of the Transandine Railway will probably never be written, unless it be given to the world by the Clark Brothers, who conceived the idea, and labored for more than a quarter of a century to enlist the assistance of the Chilean government in a plan to build the road. Every succeeding administration, during the period in which the Clarks were working on the scheme, was apparently favorable to the plan. The rejection of proposals and the failure always to vote aid or subsidy, however, was evidence of the fact that there was always secret opposition. During much of the time while the Transandine scheme was under consideration, a war cloud, arising from a disputed boundary question between Chile and the Argentine, loomed large and ominous over the Cordillera, creating a feeling in the minds of the Chilenos that Argentina was quite near enough, without an additional connecting link in the way of a railroad across the Andes. In 1901 the Transandine Railway, including the portion already in operation, from Los Andes to Salto del Soldado, passed into the hands of W. R. Grace & Company. Then John Eyre, manager for Grace & Company in Chile, took up the work of promoting the undertaking. With indomitable courage, tireless energy, and full confidence in ultimate success, he started in to enlist government aid in building the road. In February, 1903, Congress passed a law authorizing the President to advertise for a term of one year, from the first of May, 1903, for sealed proposals for the construction of the Transandine Railway. The law also provided for a government guarantee of five per cent. annually on a capital not to exceed $7,250,000. Grace & Company were the only bidders. The proposal was for $6,500,000, being $750,000 below the maximum sum on which the government guaranteed five per cent. interest. A special commission was appointed to examine the proposal, and on June 7, 1904, the tender was accepted by the government, thus insuring to Chile railway communication with countries beyond the mountain barrier that had so long restricted commerce and the development of her natural resources.
