There are other thingsthat cause too much slack in the brake rigging, such as worn brakeheads, long body rods, short truck brake connections and loosecylinder and reservoir brackets. Careful attention should begiven to detect these conditions and, of course, the matter ofbrake adjustment should be followed up at all times. RECLAIMING CAR TRUCK PEDESTALS The application of oxy-acetylene welding to worn passengercar pedestals is a practice followed by the Chicago, Burlington&• Ouincy at the Aurora shops. When the pedestals have wornto such an extent that it is impracticable to use them further,they are removed and the worn parts built up, as indicated in. Worn Jaws of Car Truck Pedestal Built Up by the Oxy-Acetylene Process the illustration. The built-up surfaces are smoothed by grindingand the pedestals are then reapplied, being practically as goodas an entirely new casting. The cost of thus repairing thepedestals is small and a substantial saving is made as comparedwith the cost of new castings. Safeguarding Dangerous Doorways.—Doors are often lo-cated so that they open directly upon railroad tracks. In suchcases prominent danger signs should be displayed; substantialrailings should also be fixed in place, just outside the doors, toprevent persons from walking directly out upon the railings should be placed wherever tracks come dan-gerously near to buildings, and if the space between a buildingand a track is so narrow that a person standing there might becrushed by a passing train, this space should be covered over byboards or by metal plates, inclined at such an angle that itis impo
