What Universal Signalling does
Universal Signalling Ltd is a Derby-based railway signalling company founded in December 2022 to commercialise intellectual property developed since 2018 by SkyBlue Engineering Ltd. The company builds a modular product family on a patent-pending Universal Interlocking (U-Lock) architecture that uses commercial off-the-shelf hardware, SIL-4 certifiable QNX real-time operating system software, and an open interface specification. Its products include U-Locate (train positioning), U-Cross (user-worked crossing protection), U-Supervise (speed supervision), U-Work (track worker protection), and U-Beacon universal locator beacons, all designed for rapid overnight deployment on lightly used and rural lines where traditional digital signalling is economically unviable.
The company's go-to-market targets rail infrastructure operators and government bodies primarily in the UK, with international expansion underway via an exclusive South American distribution agreement with Fasser Engenharia. Revenue mechanics are project-based, comprising one-time product licences, installation and commissioning services, and longer-term technology licensing (including QNX). Customers and trial partners include Network Rail, Transport for Wales, ScotRail, Coventry City Council, and Colas Rail, with regulatory milestones including Network Rail approved supplier status, Trial Product Acceptance for the U-Positioning system, and Made In Britain certification.
Universal Signalling operates with a small team of approximately 10-15 staff and has raised a fully subscribed pre-seed round of roughly £388,364 across two tranches in 2025, led by SFC Capital and anchored by the Southern Angel Investors Club. Strategic support includes co-funding from the European Space Agency BASS Program, the UK Space Agency, and InnovateUK, alongside technology partnerships with QNX (BlackBerry), TSL/HID, and Mobius Networks. The company achieved its first mainline installation on the Heart of Wales line in late 2025 and anticipates a seed round in mid-to-late 2026 to support commercial scaling.

Universal Signalling product offering
Product offeringCore offering
Universal Signalling develops and sells rapidly-deployable railway signalling products built on a patent-pending Universal Interlocking (U-Lock) architecture. The product suite includes U-Cross (user-worked crossing protection), U-Locate (train positioning), U-Supervise (speed supervision), U-Work (track worker protection), and U-Beacon locator beacons, all designed to enable signalling deployment in days rather than decades using commercial off-the-shelf hardware with SIL-4 safety certification.
Product overview
Universal Signalling offers a suite of modular, rapidly-deployable railway signalling products built on a patent-pending 'Universal Interlocking' architecture. The product family centers on U-Lock as the core interlocking system, with incremental products U-Locate (train positioning), U-Supervise (monitoring), U-Cross (user-worked crossing protection), and U-Work (track worker protection) building toward full U-Lock functionality. The physical infrastructure component, U-Beacon Universal Locator Beacons, are installed on track sleepers to enable positioning detection. The company uses Commercial Off-The-Shelf (COTS) hardware including TSL/HID RFID reader modules integrated into the technology stack, and QNX real-time operating system for safety-critical functions. Their unique value proposition is enabling signalling deployment 'in days, not decades' with an open interface specification.

Universal Signalling competitors and assessment
Company assessmentBroad incumbents
- Siemens Mobility: Global rail signalling incumbent offering interlocking (Westrace/Simis), ETCS, and CBTC solutions. Comparable because Universal Signalling competes for the same signalling upgrade budgets but with a COTS-based, faster-deployment architecture versus Siemens's traditional proprietary stack.
- Alstom: Global rail signalling incumbent with Atlas interlocking and ETCS solutions, plus a major UK rail presence including the Hitachi-Alstom JV for HS2. Comparable because Alstom is the primary incumbent Universal Signalling positions against in the UK and international mainline market.
- Hitachi Rail: Major signalling player through its Hitachi Rail STS business (formerly Ansaldo STS) with interlocking, ETCS L1 LS, and CBTC products. Comparable because it is one of the established suppliers competing for Network Rail and international mainline contracts that Universal Signalling targets.
- Thales Ground Transportation: Global rail signalling incumbent providing interlocking (LockTrac), ETCS and communications-based train control. Comparable because Thales is one of the established signalling vendors Universal Signalling must displace or complement, particularly in UK and European mainline tenders.
- Wabtec Corporation: Global rail equipment and signalling supplier following the GE Transportation merger. Comparable because Wabtec provides train control, signalling, and digital solutions to freight and passenger operators globally, including the UK and European markets Universal Signalling is targeting.
- Kontron Transportation (formerly S&T): European signalling and communications supplier providing interlocking, train protection, and rail communications solutions across mainline and urban rail. Comparable because Kontron competes in the same signalling infrastructure procurement opportunities as Universal Signalling, particularly across Central and Eastern Europe.
Direct peers
- HIMA Group: Specialist supplier of safety-critical control systems (SIL-4 safety PLCs) used in rail signalling and interlockings. Comparable because HIMA serves the same safety-critical signalling infrastructure niche with similar certification requirements, and is a potential technology or commercial partner for Universal Signalling's COTS-based architecture.
- Mermec: Italian rail technology company providing track diagnostics, signalling, and train control systems. Comparable because Mermec competes in adjacent rail technology markets (diagnostics, train detection) and serves similar mainline and metro customers to Universal Signalling.
- Indra (Rail Signalling): Spanish technology group with a rail signalling division providing interlocking, ATP/ATO, and ERTMS solutions. Comparable because Indra is a mid-sized specialist signalling competitor focused on ETCS/ERTMS deployment, similar to Universal Signalling's positioning as a focused specialist against larger incumbents.
Emerging players
- Cylus: Israeli rail cybersecurity startup serving rail operators globally. Comparable because Cylus is a venture-backed rail tech company bringing a software-led, modern technology approach to a traditionally conservative rail market — similar in profile to Universal Signalling's startup challenge to incumbents.
