What reading level is Achievements in Engineering During the Last Half Century book?
To quickly assess the difficulty of the text, read a short excerpt:
The route has been carefully surveyed, and the scheme reported on ; and the railway, according to the most recent plans, would start from Visp, in the Rhone valley, and terminate at Domo D'Ossola, in Italy, with a total length of only about 30 miles. The gradients would not exceed I in 50 on the short north-western slope, and I in 40 on the longer south-eastern slope, descending to the plains of Italy; but a tunnel about 10 miles long would be required. This tunnel, laid out so as to form two s...traight lines, meeting near the centre at an angle, in order to avoid passing under greater mountain heights, would nevertheless be 6895 feet below the surface at the highest point, more than 1000 feet greater depth than the St Gothard. The internal heat would therefore be pro- bably greater, especially as the tunnel would be at a lower level ; and this has been estimated at a maximum of 100 to 104 in the central portion, which it is considered might be made bearable for the workmen by special arrange- ments for ventilation, and for cleansing and cooling the air near the faces of the advanced headings.
