The anticipated task of maintaining communication, especially on the higher and more exposed sections of the railway, has been appreciated to the full. To deal with the snow three powerful rotary ploughs have been acquired, and one is kept in constant readiness. It is no unusual circumstance for this equipment to be called out in the middle of summer to cope with a block in one of the deep cuttings. The drift is a danger against which especial attention has to be devoted, for the wind catches up the fine, dry flakes and whirls them in clouds across the country. To prevent this being deposited upon the line, and thus obstructing traffic, timber screens have been erected beside the line, this defence continuing in an almost unbroken line for 60 miles between Mjolfjeld and Gjeilo. The provision of the line, however, is of far-reaching importance to the commercial interests of Norway. Formerly, 54 hours were required to travel between Christiania and Bergen, but now, by cutting almost straight across the peninsula, the journey can be covered in 14 hours. To forge the link of 215 miles between Vossevangen and Roa, to complete this undertaking, occupied ten years, and the £3,333,000, or $16,665,000, expended upon the enterprise is considered an excellent investment for the country. CHAPTER XXII FROM BUENOS AIRES TO VALPARAISO OVERLAND Though Meiggs was denied the glory of having built the first South American trans-continental railway, yet the idea has been carried to fruition, but at a point much farther south than he contemplated. Again, whereas the audacious Philadelphian engineer proposed only to establish his Atlantic terminus on the upper reaches of the Amazon, the completed line runs down to the water’s edge on either coast, the two opposite ports connected in this manner being Buenos Aires on the Atlantic, and Valparaiso on the Pacific, coasts. The Trans-andine railway itself, which completes this connection, however, only extends from Mendoza at the foot of the mountain chain on the Argentine side, to Los Andes on the Chilian slopes of the range. These two points are 156 miles apart, but the metals had to be lifted 11,500 feet into the air to bring them together. When it was decided to connect Mendoza and Los Andes together in this manner, the first-named town was in direct touch with the Atlantic Ocean, the Buenos Aires & Pacific railway having thrown its meshes inland to the foot of the mountains. This was not a difficult matter, owing to the flatness of the country, pampas plains for the most part prevailing. The result is that in the climb from Buenos Aires to Mendoza only 2,470 feet has to be overcome in 650 miles. Consequently, the gradients are so slight as to be practically imperceptible. Indeed, so simple was construction that it was found possible to lay the metals in an absolutely straight line for no less than 210 miles--the longest stretch of “straight” line in the world.
