ADDS TO STRENGTH OF RAILS

Invention of Frenchman Said to Over come Defect Which Has Long Been Recognized. Rails with exchangeable treads, consisting of a number of strips of very hard steel alloy sunk into their head, is a recent invention by a French engineer. The object, is , to make that part of the head which is

normally in contact with the wheels more wear-resisting, an end which cannot be attained by hardening the whole rail, for the shocks and stresses to which it is subjected make it imperative that it be of not too hard steel. The new rail is made in two forms; one, as shown by the sketch, for light traffic, having the hard-steel strips sunk into the head and held by setscrews; the other, for heavy traffic, consisting of three parts bolted together, the strips being “held between the two parts of the head. Another feature of this rail is that the hard strips may be so laid lit, that web plates, holding the ends of two lengths of rails together, become superfluous thus insuring. shockfree, smooth and noiseless running.—Popular Mechanics.
