The Influence of Rails on Street Pavements
When the streets of cities were paved with granite or trap blocks, laid on a sand foundation, with a space varying from 1 in. to 2 ins. between the blocks, which was thought necessary to afford a foothold for the horse traffic, the section of the rail selected by surface railroad companies did not add materially to the unevenness of the pavement. As a matter of fact, the first rails used were so much of an improvement on the prevalent street pavements that the traffic early developed a tendency to follow the lines of the rails. As this retarded the railroad traffic through a natural unwillingness on the part of teamsters to pull out of the track, the Hewitt or center-bearing rail, Fig. 1, was invented, with the avowed purpose of preventing vehicular traffic following the lines of the rails.
