The Rail Signaling and Train Control Systems market research study delivers current market analysis plus a five year market and technology forecast. The study is available in multiple editions including worldwide, all regions, and most major countries. This report serves as an effective planning guide for suppliers of rail signaling and train control systems and components as well as companies considering entry into this marketplace.

Fundamentals of Railway Train Control and Signaling

The system can be realized with a safety integrity level up to SIL3 depending on the requirements. The control Cabinet modules provide universal mounting possibilities, e. By separating the system into different ranges is a clear selection and different operation rights are possible Moreover, the use and involvement of superior or existing sub systems are possible. Turnout Control Systems are self-contained turnout controls that are independent from superior systems visualisations. Furthermore, additional systems like point heating systems, vehicle communication, track circuits etc. In principle, ATP systems are used to monitor train movements on single-track sections with train control operation.

Signalling and Control Systems

It is a replacement for legacy train protection systems and designed to replace the many incompatible safety systems currently used by European railways. The standard was also adopted outside Europe and is an option for worldwide application. In technical terms it is a kind of positive train control PTC. ETCS is implemented with standard trackside equipment and unified controlling equipment within the train cab. In its advanced form, all lineside information is passed to the driver wireless inside the cab, removing the need for lineside signals watched by the driver. This will give the foundation for a later to be defined automatic train operation. Trackside equipment aims to exchange information with the vehicle for safely supervising train circulation.

Signalling &Telecommunications

This entry-level course will teach you about the base systems architecture and function that are the foundation of signal and train control systems and PTC. You will benefit if you are not an expert in train control and signaling but are working with railroads or plan to be and want a basic understanding of how signal systems are designed and operated. The March offering of this course will be offered in four 4-hour modules in a live online format on:. Details on how to access the course will be sent with registration confirmation. No software is required to participate in the online course.

The maintenance of the ERNST European Railways Numbering Scheme for Telecommunications database is an ongoing activity which has the primary objective to manage and keep the database updated. The database contains values from 27 Infrastructure Managers, Railway Operators and Railway Organisations in 24 countries. The database currently contains:.

Securing a safety-critical system is a challenging task, because safety requirements have to be considered alongside security controls. We report on our experience to develop a security architecture for railway signalling systems starting from the bare safety-critical system that requires protection. We use a threat-based approach to determine security risk acceptance criteria and derive security requirements.

The safety and the correctness of signaling system not only relate to the safety and efficiency of the rail transit operation, but also link with the life safety of passengers. In order to guarantee the safety of a signaling system for metro, the safety certificate for the trial operation with carrying passengers must be obtained. In this paper, a suitable safety management and signaling system integration model are explored according to the CENELEC standards and applied in China. With taking account of the strict safety requirements for the Communication-Based Train Control CBTC system, a safety assurance and assessment method based on safety verification and validation process was put forward. This method was applied in every phase of the CBTC system development life cycle to monitor and control each activity in the life cycle and to review each document in system development process. At the same time, this method is also used to ensure the traceability of relevant documents and to test all the functions of the whole system sufficiently and completely. So that the safety operation of train control system can be ensured.


The answer depends on a number of important considerations: the current needs, the existing state of current signalling infrastructure, risk profile of the railway, short term and long term operational requirements, long term asset plans and of course the available budgets? Many of the issues are not related to signalling principles or technology but involve a whole new way of running a railway. Australian Railway signalling has relied on tried and proven track circuits of all technologies for train vacancy detection. Signal Engineers and maintainers assimilated the resolution of the traps and pitfalls through procedures, the school of hard knocks, and mentoring from the industry die-hards. The corporate experience and knowledge has resulted in continued issues being addressed or accepted to the extent that they are invisible.. Enter axle counters.
