157. Railroads and Highways. The problem of the incline is an
important one to engineers who have under their direction the
construction of our highways and the laying of our railroad tracks. It
requires tremendous force to pull a load up grade, and most of us are
familiar with the struggling horse and the puffing locomotive. For
this reason engineers, wherever possible, level down the steep places,
and reduce the strain as far as possible.
