    Brief

    Network Rail is seeking information on the supply and delivery of trackside civil infrastructure for the Future Railway Mobile Communication System (FRMCS), a critical 5G-enabled replacement for the current GSM-R communications system across the GB rail network. The FRMCS program will modernize railway communications to support mission-critical voice and data services. The trackside civils component is a major element of this rollout, encompassing approximately 4,000-5,000 masts and associated infrastructure, with potential reuse of existing GSM-R masts where feasible. This Request for Information (RFI) is issued to engage with the supply chain, understand market capabilities, and inform future procurement planning for trackside civils infrastructure. Responses will be used for information gathering purposes only and will not form part of any future tender evaluation. Suppliers are invited to provide insights on technical solutions, delivery approaches, costs, timelines, and capacity for this large-scale national railway infrastructure project.
