Diagnose, adjust, repair, or overhaul railroad rolling stock, mine cars, or mass transit rail cars

Adjust repaired or replaced units as needed to ensure proper operation. Disassemble units such as water pumps, control valves, and compressors so that repairs can be made. Examine car roofs for wear and damage, and repair defective sections, using roofing material, cement, nails, and waterproof paint. Inspect components such as bearings, seals, gaskets, wheels, and coupler assemblies to determine if repairs are needed. Inspect the interior and exterior of rail cars coming into rail yards in order to identify defects and to determine the extent of wear and damage. Install and repair interior flooring, fixtures, walls, plumbing, steps, and platforms. Paint car exteriors, interiors, and fixtures. Perform scheduled maintenance, and clean units and components. Repair and maintain electrical and electronic controls for propulsion and braking systems. Repair or replace defective or worn parts such as bearings, pistons, and gears, using hand tools, torque wrenches, power tools, and welding equipment. Repair window sash frames, attach weather stripping and channels to frames, and replace window glass, using hand tools. Repair, fabricate, and install steel or wood fittings, using blueprints, shop sketches, and instruction manuals. Replace defective wiring and insulation, and tighten electrical connections, using hand tools. Test electrical systems of cars by operating systems and using testing equipment such as ammeters. Test units for operability before and after repairs. Align car sides for installation of car ends and crossties, using width gauges, turnbuckles, and wrenches. Measure diameters of axle wheel seats, using micrometers, and mark dimensions on axles so that wheels can be bored to specified dimensions. Record conditions of cars, and repair and maintenance work performed or to be performed. Remove locomotives, car mechanical units, or other components, using pneumatic hoists and jacks, pinch bars, hand tools, and cutting torches. Repair car upholstery.

Repairing -- Repairing machines or systems using the needed tools. Equipment Maintenance -- Performing routine maintenance on equipment and determining when and what kind of maintenance is needed. Installation -- Installing equipment, machines, wiring, or programs to meet specifications. Troubleshooting -- Determining causes of operating errors and deciding what to do about it. Equipment Selection -- Determining the kind of tools and equipment needed to do a job. Quality Control Analysis -- Conducting tests and inspections of products, services, or processes to evaluate quality or performance.

Manual Dexterity -- The ability to quickly move your hand, your hand together with your arm, or your two hands to grasp, manipulate, or assemble objects. Finger Dexterity -- The ability to make precisely coordinated movements of the fingers of one or both hands to grasp, manipulate, or assemble very small objects. Near Vision -- The ability to see details at close range (within a few feet of the observer). Extent Flexibility -- The ability to bend, stretch, twist, or reach with your body, arms, and/or legs.

Repairing and Maintaining Mechanical Equipment -- Servicing, repairing, adjusting, and testing machines, devices, moving parts, and equipment that operate primarily on the basis of mechanical (not electronic) principles. Handling and Moving Objects -- Using hands and arms in handling, installing, positioning, and moving materials, and manipulating things. Inspecting Equipment, Structures, or Material -- Inspecting equipment, structures, or materials to identify the cause of errors or other problems or defects. Getting Information -- Observing, receiving, and otherwise obtaining information from all relevant sources. Performing General Physical Activities -- Performing physical activities that require considerable use of your arms and legs and moving your whole body, such as climbing, lifting, balancing, walking, stooping, and handling of materials. Controlling Machines and Processes -- Using either control mechanisms or direct physical activity to operate machines or processes (not including computers or vehicles). Identifying Objects, Actions, and Events -- Identifying information by categorizing, estimating, recognizing differences or similarities, and detecting changes in circumstances or events.
