The accompanying engravings showa gang of trackmen on the Cincinnati & Northwestern Railroad, which runs from College Hill Junction to Mt. Healthy, Ohio, usinga new rail punch, which has recently been designed by F. J. J. Sloat, . CONVEYING PUNCH ON ROAD general manager of the Southern Ohio Traction Company, Hamil-ton, Ohio. This punch contains many advantageous features, andits operation during the electrification of this steam road has beenmost satisfactory. The engravings show clearly the general appearance of the deviceand the method of punching rails while using it. The rail on theroad mentioned is 60-lb T, and was punched through the web for long bonds. The machine shown, however, is of sufficient powerto punch any sized T-rail up to 85 lbs. per yd., with a hole in.in diameter. The punch is fastened securely to the track by a smallset screw, as shown in the second cut, and the die is placedagainst the web of the rail to steady the small punch. This punchis only about 1J/2 ins. long, and can be renewed readily at small ex-pense. The device is also applicable for punching holes through the
