Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . tions, there is no overlapping or crane facilities in the machine and freight-car erect-ing .shops will be better appreciated if one will endeavor to imagine four cranes on a single runway attempting tohandle an equivalent amount of work. The Machine Equipment The machine shop is equipped with the following ma-chinery : Four automatic sjxicing punches, five copingpunches, five high-siJeed punches, two horizontal punches,one 7-ft. 6-in. gate shear, one angle shear, one 36-ft. plate-edge planer, one 30-in. circular saw, one 30-in. metal bandsaw, one 7-ft. plate roll, one 10-ft. brake, one bulldozer,two special plate-drilling machines, and miscellaneous drillpresses, all driven bj*independent motors. The arrangement of the machines is such that the mate-rial after each operation moves forward in the direction ofthe erecting shops, backward movement being carefullyavoided, thereby reducing material handling to a mini-mum. The high-speed punches are belt-driven direct from. storage Yard Along Front of Steel-Car Shop motor to flywheel, gears being dispensed with. Clutchesare of the 6-point type. The heads are equipped with twopunches which are controlled by gag levers. These ma-chines are well adapted for punching the smaller platesfor which metal templets are made up and into whichholes are drilled; by inserting a pin or gage in each suc-cessive hole and butting the plate against the pin, the de-sired spacing is obtained. In certain classes of work theoperator can move the material fast enough to catch everyhole with the punch running at the rate of 60 strokes perminute. An unusual plan was followed as regards the installa-tion of machines for heavy punching. The usual practicehad been to install a small number of high-capacity ma-chines for the punching and slotting of the sills, sideplates, and similar members, necessitating frequent chang-ing of dies
