Introduction & Electrical Foundations
These courses cover the absolute basics of railway signalling, wiring, and general safety installation skills.
The City & Guilds 3668 Level 3 qualification provides a comprehensive foundation in communications cabling and telecommunications systems. The selected units (301, 302, 303, 306, 307 and 308) collectively develop the technical knowledge and practical skills required to design, install, test, and maintain both traditional copper and modern fibre network infrastructures.
Develop core wiring and termination competencies specific to signalling equipment rooms, location cases, and trackside cabinets. Covers safe isolation, cable identification, and compliance with Network Rail installation standards.
Track Circuits & Interlocking Systems
This category focuses on asset types used to detect train presence on a section of track and the logic systems (interlockings) that safely clear signals.
Learn the theory and practical operation of AC-fed track circuits used for train detection, including tuning, bonding, and adjustment procedures for reliable occupancy indication.
Covers the fundamentals of DC track circuit design, battery feed arrangements, rail impedance, and relay operation for detecting train presence on plain line and within station limits.
Point Machines & Level Crossings
These modules train staff on the heavy trackside equipment responsible for diverting trains between tracks and managing public crossings.
Foundation module covering the mechanical and electrical principles common to all point machine types, including detection circuits, drive mechanisms, and safe working practices.
Full lifecycle maintenance training for HW1000 and HW2000 point machines, covering installation, commissioning, routine servicing, and fault diagnosis on these clamp-lock units.
Maintenance, Fault Finding & Testing
Dedicated to technicians and engineers who test new installations or diagnose infrastructure failures. It includes standard Signalling Electronic Maintenance (SEM) blocks and formal IRSE-aligned testing modules.
Signalling Electronic Maintenance Block 1 — introduces fundamental electronic diagnostic techniques, test equipment familiarisation, and systematic fault-finding on signalling control systems.
Signalling Electronic Maintenance Block 2 — builds on SEM 1 with advanced PCB-level diagnostics, data communication testing, and component-level repair procedures for modern signalling assets.
Train Protection & Modern Signalling
Advanced or modern digital trackside infrastructure designed for train safety and automated protection systems.
Training on the Train Protection and Warning System, covering trackside equipment installation, testing, and maintenance of speed traps, OSS loops, and AWS/TPWS integration.
Covers Signal Post Warning Electrical Equipment — its installation, commissioning, and maintenance for providing audible and visual warnings to trackside workers at signal locations.
