Network Rail Compliant RAMS for Tier 2 Contractors

Network Rail's principal contractor supply chain operates under RISQS (Railway Industry Supplier Qualification Scheme) accreditation, which requires all Tier 2 and Tier 3 contractors to maintain demonstrable H&S management systems, including a full audit trail of RAMS for every possession and infrastructure task. A rejected or inadequate RAMS delays a possession window — a failure that has significant commercial and reputational consequences for rail contractors.

The Safe System of Work (SSoW) is the core document that governs how workers are protected from train movements on the operational railway. Your method statement must explicitly define the SSoW type — whether Separated, Fenced, Lookout Warning, or Line Blockage — and document the roles of the COSS (Controller of Site Safety), IWA (Individual Working Alone), and any Engineering Supervisors. A RAMS that vaguely references 'safe working practices near the line' without specifying the SSoW will not pass Network Rail review.

Sentinel scheme compliance requires that every operative's Sentinel card number, PTS (Personal Track Safety) certification, and COSS reference are recorded within your documentation before any possession begins. This is a hard regulatory requirement, not a recommendation. Your RAMS software must be able to capture and display these details in a structured way that COSS personnel can brief from before the shift starts.

Fatigue management is a specific requirement under NR/L2/OHS/003, which mandates risk assessments for short-interval possessions, night-working, and consecutive shifts. The HSE's Working Time Regulations 1998 also apply. Failure to address fatigue in your RAMS for night possessions is a common audit finding that can jeopardise your RISQS accreditation renewal.
