Core Responsibilities

Primary Functions

Operate a variety of machine tools, including manual and CNC lathes, milling machines, grinders, and drill presses, to produce or recondition locomotive parts to precise specifications.
Read and interpret complex technical documents, such as blueprints, engineering drawings, schematics, and repair manuals, to determine machining procedures.
Perform high-precision measurements on components using tools like micrometers, calipers, bore gauges, and dial indicators to ensure adherence to strict tolerances.
Disassemble, thoroughly inspect, diagnose, and meticulously reassemble critical locomotive systems, including diesel engines, power assemblies, traction motors, and wheelsets.
Troubleshoot and identify the root cause of mechanical failures in complex systems, applying deep mechanical knowledge to formulate effective repair plans.
Machine new or refurbished parts from raw stock, such as custom bushings, shafts, pins, and gears, ensuring perfect fit and function.
Conduct skilled welding and fabrication tasks using MIG, TIG, or stick processes to repair cracks, build up worn surfaces, or create custom brackets and fixtures.
Perform comprehensive maintenance, repair, and overhauls on vital air brake systems, air compressors, and associated pneumatic components according to federal regulations.
Rig, lift, and move heavy locomotive components, such as engines and wheel assemblies, using overhead cranes, hoists, and forklifts with a paramount focus on safety.
Test and validate the functionality of repaired or newly machined parts and assemblies to confirm they meet or exceed operational and safety standards.
Maintain impeccable and detailed records of all maintenance work, parts consumed, and time spent, utilizing a Computerized Maintenance Management System (CMMS).
Set up, program (basic G-code/M-code), and operate CNC machinery to efficiently produce complex, high-tolerance components.
Perform intricate bench work which includes filing, deburring, lapping, and precision fitting of mechanical components and assemblies.
Diagnose and repair hydraulic and pneumatic systems found on both locomotives and shop support equipment, ensuring their reliable operation.
Evaluate worn, damaged, or failed parts to determine the most cost-effective course of action: repair, remanufacture, or replacement.
Ensure all work performed is in strict compliance with all company policies and external regulatory standards, including AAR and FRA guidelines.
Fabricate custom jigs, fixtures, and specialized tooling to improve the efficiency, accuracy, and safety of repair and manufacturing processes.
Proactively perform and document preventative maintenance on all shop machinery and equipment to maintain a state of operational readiness and safety.
Collaborate closely with a diverse team of craftspeople, including electricians, carmen, and welders, to execute complex, multi-disciplinary repair projects.
Actively participate in daily safety briefings, job hazard analyses, and continuous improvement initiatives to foster a world-class safety culture within the facility.

Secondary Functions

Assist in the practical training, mentorship, and skill development of apprentice machinists, sharing knowledge and expertise.
Contribute to inventory management by monitoring stock levels of raw materials, tooling, and frequently used parts, and reporting needs.
Collaborate with engineering and planning departments to provide feedback on repair procedures and suggest improvements for component design or manufacturability.
Participate in regular safety audits and shop housekeeping programs to maintain a clean, organized, and safe work environment.
