✦ Synopsis

report, That the system embraces a form of construction for street railways that dispenses with wooden sills and crossties, and substitutes therefor metal chairs and tie-bars as supports and braces, for a system of double rails of peculiar construction, in which the head and flange rails are separate, each having a wide depending web directly under the loadbearing surface. These two sections, when united, form a complete rail, making a very stiff longitudinal stringer, laid VOL. CXXXIII.
