What reading level is The Elements of Railroading a Series of Short Essays Reprinted From the Railro book?
To quickly assess the difficulty of the text, read a short excerpt:
An ideal track, such as this, may not be altogether attainable, yet it should be continually approached, with the knowledge that every de- parture from the ideal condition is a certain cause of expense. This perfect condition demands, first, that the surfaces of the rails shall be exactly true to the plane of the grade, so that no vertical shock shall be given to the wheels as they roll over the track ; and second, that the line of the rails shall be so true that the flanges of the wheels will ...seldom touch them, and then without a jar. If the speed of all trains were uniform, the elevation of the outer rails^could be so exactly ad- justed as to fulfill this second demand upon curves, as well as upon straight lines; since, however, the speed of trains varies widely, it is necessary to " split the difference " and to accept an elevation too great for low speeds and really less than is desirable for high speeds. It is safer, with our tendency to higher speeds, to adopt a higher elevation than the average rate would require.
