Key Responsibilities and Required Skills for Junction Maintenance Technician

🎯 Role Definition

A Junction Maintenance Technician is a specialized field technician responsible for the inspection, preventative maintenance, repair and reliable operation of railway junctions, turnouts (switches), frogs, point machines, derailers and the interface between track and signaling equipment. This role emphasizes safety-first fieldwork, accurate diagnostics, hands-on mechanical and electrical repair, and clear documentation in a maintenance management system (CMMS). Ideal candidates combine track-structure know-how with signaling awareness, strong troubleshooting skills, and the ability to execute work in a scheduled and emergency-response environment.

Core Responsibilities

Primary Functions

Perform routine, preventive and corrective maintenance on switches, points, frogs, check rails and related turnout components, ensuring safe and reliable operation of all junction assets according to company and FRA standards.
Diagnose mechanical and electrical faults on point machines, motor drives, proximity detectors, switch heaters and remote locking devices using handheld test equipment, multimeters, and manufacturer troubleshooting guides.
Inspect turnout geometry, gauge, heel/wing wear, and rail profile; measure and document deviations, and perform adjustments, tie replacement, ballast tamping, and alignment to restore correct track geometry.
Execute emergency turnout repairs 24/7 during service disruptions, rapidly isolating faults, performing temporary repairs or component swaps and coordinating with dispatch and signal engineers for safe train movements.
Replace, repair or modify switch stands, stretcher bars, switch rails, slide chairs, switch points, pad plates, and stock rails; secure and torque fasteners per specification and log parts usage in CMMS.
Install, calibrate and test switch heating systems (electric and gas), monitoring thermostats and heaters for winter readiness and replacing sensors or controllers as required.
Inspect, maintain and adjust point locking mechanisms, detectors, relays and insulated joints to ensure correct occupancy detection and interlocking logic with signal systems.
Conduct routine lubrication and greasing of moving components including switch blades, bearings and pivot points, using approved lubricants and grease guns to reduce wear and promote reliable operation.
Perform diagnostics and minor repairs on track circuits and wayside signal equipment closely interfacing with junction assets, and coordinate escalations with signal engineers for complex electrical faults.
Carry out welding, metal fabrication and component repair tasks (including basic MIG/TIG or oxy-acetylene work where qualified) to repair frog plates, liners and broken rail fixtures per approved procedures.
Use track maintenance equipment such as tampers, spike drivers, ballast regulators and track gauges, setting up machines safely and performing handback inspections after machine operations.
Replace or repair crossties/ties (wood, concrete or composite) at junctions, ensuring proper fastening system installation and gauge stability following tie replacement.
Remove obstructions, clear ballast and maintain adequate drainage at junctions to prevent water-related track degradation and operational issues.
Complete pre- and post-shift inspections of assigned junctions and interlockings, recording conditions, anomalies and completed work in the CMMS and daily field logs.
Participate in scheduled commissioning and decommissioning of junction components for track projects and coordinate safe work protection (track permits, block protection) with train operations.
Support signal engineers during interlocking tests, lightning and outage restoration by providing mechanical access, local isolation and verification of switch machine operation.
Perform acceptance and quality checks after contractor work on junctions or during capital renewal projects, verifying compliance to plans, specifications and company standards.
Maintain spare parts inventory for junction components, manage toolkits and ensure specialized spares (motors, detectors, heaters) are stocked to minimize down time.
Deliver on-the-job training and mentoring for junior technicians in switch maintenance best practices, safe work methods and correct use of tools and measurement instruments.
Respond to and investigate derailments, switch misalignments or component failures at junctions, collect evidence, document findings, and execute immediate remedial actions to restore safe service.
Follow and enforce all safety protocols including Roadway Worker Protection (RWP), lockout/tagout (LOTO), confined space procedures, and PPE usage while working on or near live tracks or energized equipment.
Participate in continuous improvement initiatives to optimize maintenance intervals, parts standardization, and cost-effective repairs based on failure-mode analysis and reliability data.
Coordinate with freight and passenger operations, dispatch and control centers to schedule maintenance windows, outages and possessions while minimizing impact to service and passenger safety.
Interpret engineering drawings, track alignment plans, ballast profiles and signaling schematics to correctly execute planned maintenance, upgrades or renewals at junction locations.

Secondary Functions

Record and update maintenance activities, hours, materials and labor in CMMS; produce accurate work orders and condition reports to support asset lifecycle management.
Support scheduled capital works and renewals by providing field verification, staging of materials and quality assurance for junction-related deliverables.
Participate in cross-functional reliability and safety meetings to share defect trends, near-miss reports and suggested mitigations to reduce repeat failures at critical junctions.
Maintain tools, vehicles and specialized test equipment in safe operating condition; coordinate calibration and repair of meters, gauges and heaters.
Support ad-hoc data requests from maintenance planning by providing field measurements, failure histories and photographic evidence to inform predictive maintenance models.
Assist in developing and updating standard operating procedures (SOPs), maintenance checklists and emergency response plans specific to junction assets.
Provide input to spare-parts forecasting and procurement by reviewing wear rates, mean time between failures (MTBF) and lead times for critical turnout components.
Participate in training programs, competency assessments and certification renewals; maintain records of training for audit and compliance.
Liaise with contractors, inspectors and third-party auditors during maintenance, ensuring contractor work meets internal and regulatory standards.
Engage in on-call rotation and rapid-response planning for off-hours incidents, ensuring coverage and quick restoration of junction equipment.
