This migration will strengthen mission-critical voice and data capabilities, whilst supporting existing operational railway systems. FRMCS rollout will comprise three core technical aspects: 1.Trackside civils - potentially 4,000 - 5,000 masts (including some potential re-use of existing GSM-R masts) and associated infrastructure 2.Train fitment - radio and associated equipment on all trains across the network 3.FRMCS active network - Core, RAN etc. Trackside civils is a critical focus area for FRMCS delivery & Network Rail is therefore issuing this Request for Information (RFI) to engage with the supply chain and inform potential future procurement of FRMCS trackside civils infrastructure. Please note that any content received via response to this RFI will be used for information purposes only and will not be deemed as forming part of any proposed bid now, or any potential future tender. ## CPV classification Construction and ancillary works for telephone and communication lines Construction work for pipelines, communication and power lines Optical telecommunication cables Optical-fibre cables for data transmission Masts Towers, lattice masts, derricks and pylons Lattice masts Radio masts Telecommunications facilities Source Find a Tender (UK) · Notice ocds-h6vhtk-06e7cc-2026-08-19T17:40:19+01:00 [View official notice](https://www.find-tender.service.gov.uk/Notice/ocds-h6vhtk-06e7cc-2026-08-19T17:40:19+01:00) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
