Key Responsibilities and Required Skills for Junction Supervisor Assistant

🎯 Role Definition

The Junction Supervisor Assistant supports safe, efficient operation and maintenance of a rail junction (or road/traffic junction operations in some contexts) by assisting the Junction Supervisor with daily supervision, inspections, safety compliance, crew coordination, and administrative tasks. This role acts as a hands-on operational lead: performing pre-shift briefs, conducting equipment and track checks, coordinating with dispatch and contractors, documenting events, and stepping into decision-making during incidents. Ideal for candidates with field experience in track, signaling, or transport operations who want to develop supervisory skills.

Core Responsibilities

Primary Functions

Assist the Junction Supervisor in coordinating day-to-day junction operations, ensuring trains pass through the junction according to schedule while maintaining safety and regulatory compliance.
Conduct thorough pre-shift briefings and handovers with incoming/outgoing crews, communicating critical operational notes, planned maintenance windows, and safety concerns.
Inspect switches, points, crossings, and associated hardware before and during shifts; identify defects, document findings, and initiate immediate remedial action or escalate to maintenance crews.
Operate and monitor signaling and interlocking equipment as authorized; verify indicator statuses, report abnormalities, and follow standard troubleshooting steps under supervision.
Coordinate daily maintenance work with internal crews and third-party contractors, ensuring track possessions, work permits, and protection (flagging/track blocks) are in place and executed per SOPs.
Maintain accurate shift logs, defect registers, and incident reports using company systems (paper and computerized CMMS), ensuring data integrity for audits and KPI reporting.
Respond to operational incidents (derailments, signal failures, trespasser events, grade crossing emergencies) by following incident command protocols, securing the site, and coordinating with emergency services and dispatch.
Support planning and scheduling of preventative maintenance and inspection programs for switches, signaling gear, and track infrastructure to minimize junction downtime.
Verify and manage permit-to-work procedures (hot work, isolation, electrical access), ensuring proper authorizations, risk assessments, and safety briefings are completed prior to commencement.
Assist in root-cause investigations of operational incidents and near-misses; collect evidence, interview witnesses, compile timelines, and help implement corrective actions and preventive measures.
Supervise and mentor junior maintenance staff or temporary crews on safe work practices, correct use of tools and PPE, and adherence to company safety standards.
Ensure compliance with federal/state/provincial rail safety regulations (e.g., FRA, Transport Canada) and internal company safety management systems during all junction activities.
Manage the inventory of critical spares and consumables used at the junction (switch lubrication, heaters, signaling relays, batteries) and place orders to replenish stock in a timely manner.
Conduct routine environmental and vegetation inspections around the junction and coordinate removal or mitigation to preserve sightlines and track integrity.
Perform basic hands-on maintenance tasks as needed (e.g., switch cleaning, grease point lubrication, minor mechanical adjustments), escalating complex repairs to qualified technicians.
Liaise with train dispatchers and operations control to implement temporary speed restrictions, signal overrides, or platform adjustments while maintenance or inspections occur.
Monitor and enforce site traffic control and grade crossing protections during maintenance activities, ensuring public and worker safety.
Prepare and present shift performance summaries, KPI metrics (availability, MTTR, incidents), and work completion reports to the Junction Supervisor and operations management.
Participate in operational audits and inspections, implementing corrective actions for non-conformances and tracking closure of safety items.
Facilitate crew rotations, training schedules, and competency tracking for junction staff, coordinating with HR and training departments to maintain certification currency (flagging, first aid, signal safety).
Implement energy isolation and grounding procedures for electrical equipment during maintenance under the guidance of the Junction Supervisor.
Support implementation of engineering change requests at the junction by coordinating pilot tests, temporary protections, and communicating impacts to operations.
Maintain effective two-way communication on radios and mobile platforms with field crews, control center, and contractors to ensure continuous situational awareness.
Assist with emergency drills and tabletop exercises focused on junction incidents (signal failure, switch freeze, derailment) to validate response plans and readiness.
Ensure accurate mapping and GIS updates for junction assets, flags, and defects to support long-term maintenance planning and digital twin initiatives.

Secondary Functions

Support ad-hoc operational data requests, providing shift logs, defect histories, and inspection records for analysis by reliability or engineering teams.
Contribute to continuous improvement efforts by recommending process improvements to junction SOPs, maintenance planning, and shift handover templates.
Collaborate with business units to translate operational challenges at the junction into engineering requirements or capital projects.
Participate in sprint planning, safety review boards, and cross-functional workshops to integrate field feedback into maintenance and reliability programs.
Assist in pilot deployments of condition monitoring technologies (switch point sensors, axle counters) and help validate data against physical inspections.

Required Skills & Competencies

Hard Skills (Technical)

Knowledge of railway signaling systems, interlocking logic, and common failure modes.
Hands-on experience inspecting and maintaining switches, points, and track components (frogs, guard rails, switch heaters).
Proficiency with permit-to-work systems, lockout/tagout, and electrical isolation procedures.
Experience using computerized maintenance management systems (CMMS) to log defects, schedule work, and close work orders.
Understanding of local and national rail safety regulations (FRA, Transport Canada, ORR, as applicable) and compliance reporting.
Radio communication best practices and familiarity with dispatch/operations center protocols.
Basic mechanical and electrical troubleshooting skills for field-level repairs and diagnostics.
Ability to read and interpret track diagrams, signaling schematics, and junction layout plans.
Experience with track possession planning, temporary speed restriction implementation, and flagging procedures.
Familiarity with GIS asset records, inspection tablets, and mobile data collection platforms.
