We develop safe and secure railway solutions
Modern railway systems must operate reliably for decades, withstand extreme environmental conditions, and at the same time meet growing regulatory requirements for safety and security.
As an experienced railway development partner, we support manufacturers and operators from system architecture through embedded software development to integration, verification and secure operation – compliant with standards, economically viable, and practical.

Electronics & Embedded Software: Engineering for rolling stock, infrastructure and control & signalling technology
Whether interlocking, vehicle control, track monitoring or train communication – modern railway systems are based on high-performance electronics and embedded software. They must operate reliably for many years, withstand extreme environmental conditions, and at the same time meet increasing requirements for safety, availability and maintainability.
From the initial system architecture through electronic and embedded software development to integration, verification and series support, we accompany our customers in safety-critical railway applications:
- ✓Control and signalling technology – interlockings, points control systems and signalling technology
- ✓Rolling Stock Engineering – control units for rolling stock and auxiliary functions
- ✓Infrastructure – track monitoring, sensor technology and diagnostic systems
- ✓Communication systems – networked control units and communication platforms
Functional Safety: Consulting and development for safety-related railway technologies
Safety-critical railway systems must operate reliably at all times – even when faults occur. NewTec supports customers in developing safety-related systems in accordance with current CENELEC standards EN 50126 (RAMS process and lifecycle), EN 50129 (safety case) and EN 50716 (RAMS process and system lifecycle). We regard functional safety not as a downstream verification step, but as an integral part of the entire development process – from system definition through to the safety case.
- ✓Safety Consulting – conceptual consulting, RAMS analyses, safety assessments
- ✓Safety Engineering – safety management, functional safety engineering, support throughout the safety lifecycle
- ✓Assessment of Functional Safety – safety cases, hazard log, documentation
- ✓Validation – safety reviews, verification planning, evidence documentation
Cybersecurity: Security-by-design for railway systems – from threat analysis to secure operation.
The digitalisation and networking of modern railway systems open up new possibilities – while at the same time increasing the requirements placed on their cybersecurity. NewTec supports manufacturers and operators in establishing cybersecurity as an integral part of product development – in compliance with the Cyber Resilience Act (CRA), NIS-2, IEC 62443 and the railway-specific standard TS 50701.
- ✓Security Consulting – gap analysis, process consulting, training
- ✓Threat & Risk Analysis – TARA, risk and threat analyses, security requirements
- ✓Security Engineering – security-by-design, secure coding, hardening concepts
- ✓Secure Operation – security monitoring, PSIRT, vulnerability and patch management
- ✓Toolchain for PKI and certificate management
Train Communication: TRDP (Train Realtime Data Protocol) – the common standard for network communication in trains
Today's rail vehicles feature numerous networked components from a wide range of manufacturers – with steadily increasing requirements for the bandwidth and reliability of train networking. The IP-based TCN protocol TRDP, specified in IEC 61375-2-3, forms the common basis for network communication in trains. As recognised TRDP experts and full TCNOpen members, NewTec offers manufacturers and OEMs a complete TRDP package from a single source:
- ✓Consulting & Project Support – architecture reviews, requirements engineering (TRDP & SIL)
- ✓Development & Testing Services – bespoke TRDP solutions incl. safety (SDTv2) and security
- ✓Training & Coaching – introductory seminars, expert workshops, process assessments
- ✓NTOnTrack Test Environment: the flexible, automatic test system for TRDP

Der Eisenbahnsektor gilt als kritische Infrastruktur und unterliegt damit strengen europäischen und nationalen Vorgaben. Steuergeräte in Fahrzeugen, Leit- und Sicherungstechnik und Infrastruktur übernehmen sicherheitskritische Funktionen, kommunizieren über standardisierte Netzwerke und müssen dabei über viele Jahre zuverlässig, verfügbar und wartbar bleiben. Gleichzeitig steigen die regulatorischen Anforderungen an Functional Safety und Cybersecurity kontinuierlich – etwa durch den Cyber Resilience Act, NIS-2 oder die bahnspezifische Cybersecurity-Norm TS 50701. Als Entwicklungsdienstleister für Bahntechnik deckt NewTec die gesamte Bandbreite dieser Anforderungen ab: von der Elektronik- und Embedded-Softwareentwicklung über die funktionale Sicherheit nach EN 50126 und EN 50129 bis zur Cybersicherheit nach TS 50701 und IEC 62443. Ergänzt wird dieses Spektrum durch unsere langjährige Expertise in der Zugkommunikation nach IEC 61375, insbesondere im TRDP-Protokoll (Train Realtime Data Protocol), bei dem NewTec als Mitentwickler des Standards und TCNOpen-Vollmitglied zu den ausgewiesenen Experten zählt. Unser Ansatz versteht Engineering als mehr als reine Entwicklung: Sichere und cyberresiliente Bahnsysteme entstehen nicht durch einzelne Technologien oder Normen, sondern durch das Zusammenspiel von Systemverständnis, Engineering-Kompetenz und langjähriger Projekterfahrung – über den gesamten Produktlebenszyklus hinweg, von der ersten Systemarchitektur bis zur Integration, Verifikation und dem sicheren Betrieb im Feld.
Enable, Build & Maintain
Our goal is to bring safe systems into the world, across the entire lifecycle and across every industry. We know the standards and the regulations that apply to your product.
Let's talk about your railway project.
Whether it's a TRDP hands-on workshop, custom development or conformance testing, we listen first and then propose the right next step.
