RAILWAY
Over the past 20 years, Intecs has developed and tested safety-critical systems for railway signaling applications in compliance with industry standards (CENELEC EN 50126, 50128, 50129).
Today, the railway market focuses on increasingly innovative solutions, from software development to final product delivery through design, development, customization, and testing phases. Examples include Automatic Train Protection (ATP) and Automatic Train Control (ATC) systems, as well as Automatic Train Operation (ATO) systems.
RAILWAY SAFETY SYSTEMS
Leveraging its experience in “safety-critical” applications in the aerospace and defense domains, Intecs has transferred this knowledge to the railway sector, collaborating with the leading Railway Safety Certification Bodies in Italy. This synergy has enabled Intecs to support clients in the safety certification process for their products.
COMPLIANCE WITH INDUSTRY STANDARDS
Intecs’ work in railway signaling is guided by international standards, particularly the clauses defined in CENELEC EN 50126, 50128, and 50129.
INNOVATIONS IN RAILWAYS
Intecs has always been committed to the development of innovative railway solutions that use the latest available technologies. Artificial intelligence is undoubtedly the new frontier with which the railway world must confront itself, both from a technical and regulatory point of view, but satellite localisation systems also represent an important element of novelty in railway signaling. Currently, train localisation is achieved, in the vast majority of cases, with the help of complex and costly ground systems, which could be completely or partially replaced by precise and reliable satellite localisation. In this context, ATO (Automatic Train Operation) systems are also included, which are capable of driving the train without a conductor on board, transferring the implementations already active in the metropolitan environment (driverless metro) to the railway system.
Software Layer Development
Intecs technicians are also specialized in the development of onboard software layers: Common Software that implements procedures for managing the vital architecture, Safety Communication layer, and software specific to equipment.
Porting of Operating Systems and Development of Boot/Loader
Further solutions created by Intecs engineers include porting proprietary operating systems to different platforms, developing custom boot/loaders, drivers for proprietary boards, self-diagnosis routines, logging utilities, and specific software.
SOLUTIONS FOR VERIFICATION AND VALIDATION
Intecs offers specialized solutions at the software and system level, such as independent verification and validation of software activities and those related to safety-critical systems in line with CENELEC EN 50126, 50128, 50129 standards.
SPECIALISED IN:

EN 50716
Railway Applications – Requirements for software development
EN 50129
Safety related electronic systems for signalling
EN 50126
The Specification and demonstration of Reliability, Availability, Maintainability and Safety (RAMS)
EN 50128
Software for Railway Control and Protection Systems
CENELEC Standard 50716
The standard
This European standard specifies the procedures and technical requirements for the development of programmable electronic systems to be used in railway applications. It replaces the EN 50128 and EN 50657 standards. It is intended for use in any area where safety implications are involved. These may range from highly critical ones, such as safety signaling, to non-critical ones, such as management information systems. These systems can be implemented using dedicated microprocessors, programmable logic controllers, multi-processor distributed systems, large-scale central processor systems, or other architectures.
The course
A comprehensive two-day course provides participants with all the key features of the standard, along with an overview of the proposed implementation techniques that are both effective and efficient.
Duration
The nominal duration of the course is 2 days; however, the course can be compressed into a 1-day course to meet customer needs.
Target audience
Software engineers (development and verification), quality engineers, configuration managers, test engineers, and project managers.
Methods and media
Classroom presentations with PowerPoint slides.

CENELEC Standard 50129
The standard
This European standard is the first to define the requirements for the acceptance and approval of safety electronic systems in railway signaling. Safety electronic systems for signaling include both hardware and software aspects. To install complete safety systems, both parts must be considered throughout the entire system life cycle. The standard consists of the main part defining the requirements and annexes A, B, C (regulatory) D, E (informative).

CENELEC Standard 50126
The standard
This European standard provides railway authorities and the railway support industry across the European Union with a process that will enable the implementation of a consistent approach to the management of reliability, availability, maintainability, and safety, known by the acronym RAMS. It can be systematically applied at all stages of the life cycle of a railway application to develop specific RAMS requirements for the railway industry and to achieve compliance with those requirements. The approach defined in this standard is consistent with the application of the quality management requirements contained in the ISO 9000 series of international standards.
