#10478 - STA (12 months) Interfaced Overlay Miniature Stop Lights

Tender description

This tender is addressing two requirements. The need to renew existing contracts for Overlay Miniature Stop Light systems (Lot 2) and to find suppliers for two new solutions to be developed through STE’s R&D programme (Lot 1 and Lot 3). It is worth noting that the technical part of the Pre-Qualification Questionnaire (PQQ) includes questions relating to the Rail Industry Readiness Level (RIRL). Additionally, where there is a commercial commitment from NR, as solutions are being purchased, NR owning the IPR is not required. The following Safety Integrity Levels (SIL) apply to each lot: - Lot 1 - Safety Integrity Level (SIL) 2, Overlay Miniature Stop Light - Lot 2 - Minimum Safety Integrity Level (SIL) 3, Overly Miniature Stop Light - Lot 3 - Minimum Safety Integrity Level (SIL) 3 Interfaced Overlay Miniature Stop Light (IOMSL) The above Safety Integrity Levels have been based on the crossing type and characteristic of the usage in order to determines which SIL level is deployed.
