Sir—Having been practically engaged in the construction of rail- ways for some years, my attention, about three years since, was directed to the designing a rail that should overcome several of the disadvantages, if not failures of the then, as well as the one still used, of intermediately supported rails. My observations were then, and are now, with regard to that des- cription of rails at present used. First, that the greatest strength of the rails is not in the direction of the force which they are intended to bear. Second/i/, that there is invariably considerable attrition between the rail and chair, and between the joints of the rails, and from which a portion of the useless noise so much complained of on Railways arises. Tliirdly, the fixing of the rails is subject to failure, by the loosening of the key or wedge that is used to fix them in the chair from the attrition consequent upon the imperfect connection between two hard surfaces, or from the wooden wedge Iiaving greater force to sustain than it is able without being compressed. Fourthly, from the great force required to roll the irregular forms of the present rails, the same are very frequently flawed or frac- tured by the force applied to change the metal to the form so widely different from the bar converted, or otherwise in cooli
