Temporary Block Working is a vital safety procedure designed to ensure the secure and controlled movement of trains when there is a failure or planned maintenance on signalling systems or track infrastructure. This system is implemented when normal signalling cannot be used, allowing train movements to continue safely by relying on manual authorisations from signallers and/or hand-signallers.

Key features:

• Enhanced Safety: Ensures trains can still operate in areas with disrupted signalling by allowing controlled, authorised movements.
• Compliance with Railway Standards: Fully aligns with industry safety protocols, including RSSB standards.
• Manual Oversight: Train drivers and signallers work together to maintain operational safety, with clear communication protocols in place.
• Critical in Emergencies: Often used in emergency or degraded conditions, such as signal failures, track issues, or engineering work.

Temporary Block Working is an essential operational measure, providing a robust solution for maintaining rail network continuity while prioritising safety during abnormal conditions.
