Note 106 — Chapter VII · ROADS AND RAILWAYS

Certain duplications in the actual scheme of the railways are due to this need to correct a line that had been planned hastily and was useless. The line from Justo Daract to La Paz (1912), on the Pacific railway, avoids the steep inclinations of the first line, which followed the course of the wagon-road via San Luis. The interpretation of the relief is particularly difficult in a country which has not been shaped by normal erosion. Blunders detected by later topographical inquiries were similarly committed in constructing the Patagonian railways.
