Execute corrective maintenance to address defects found during inspections or reported by operators, ensuring timely and effective resolution to minimize vehicle downtime.
Interpret and apply technical information from complex engineering drawings, wiring diagrams, schematics, and manufacturer service manuals to guide repair processes.
Operate and test trams within the maintenance facility and on the mainline to verify that repairs have been successfully completed and the vehicle operates safely.
Perform wheel truing and profiling on a wheel lathe to maintain optimal wheel-to-rail contact and ensure passenger comfort and safety.
Service and repair on-board HVAC systems, including refrigerant recovery and recharging, compressor replacement, and control system diagnostics.
Inspect, maintain, and repair pneumatic systems, including air compressors, dryers, governors, and brake control valves to ensure reliable braking performance.
Address and repair issues within the vehicle's high-voltage propulsion and auxiliary power systems, following strict high-voltage safety and lockout/tagout procedures.
Maintain and troubleshoot microprocessor-based electronic control systems, including Vehicle Control Units (VCUs) and other PLCs that manage vehicle functions.
Conduct running repairs on the tram's interior and exterior, including seats, windows, lighting, flooring, and body panels to maintain a state of good repair.
Respond to service calls for disabled vehicles on the mainline, performing rapid diagnostics and repairs to restore service as quickly and safely as possible.
Perform modifications and component upgrades to the tram fleet as directed by engineering bulletins or fleet improvement campaigns.
Utilize a variety of hand tools, power tools, and specialized equipment such as multimeters, oscilloscopes, hydraulic presses, and lifting jacks.

Secondary Functions

Meticulously document all maintenance activities, including labor hours, parts used, and detailed descriptions of work performed, within the organization's Computerized Maintenance Management System (CMMS).
Maintain a clean, safe, and organized work environment in the maintenance facility, adhering to all safety protocols, including the use of personal protective equipment (PPE).
Collaborate effectively with fellow technicians, supervisors, and operations staff to coordinate maintenance efforts and ensure efficient workflow.
Participate actively in ongoing technical training and professional development to stay current with new vehicle technologies and repair methodologies.
Provide technical assistance and guidance to junior technicians, contributing to a culture of shared knowledge and continuous improvement.
Assist in managing the inventory of spare parts and materials, identifying needs, and reporting low stock levels to ensure parts availability for future repairs.
Support accident or incident investigations by providing technical analysis and detailed information regarding the condition of the involved vehicle.
