“…The Chinese Train Control System (CTCS) is very similar to the ETCS system (Ning, et al, 2004) but with the levels defined slightly differently as shown in o ITCS certification through Amtrak's request for expedited certification process is pending successful resolution of a few remaining issues prior to FRA approval for certification.…”

EXECUTIVE SUMMARY AND ABSTRACTIn this report I detail how I have investigated the feasibility of producing a systems engineering framework that can be applied to all forms of Railway Control & Safety (RCS) systems in order to simplify their development, delivery and implementation. Based on this research, I propose two simple models that can be used to model conventional signalling, ERTMS, CBTC and PTC systems; a functional model and a physical model. I have looked into how these models can be utilised to model specific systems and how this can then be used to identify the high-level functionality and interfaces of individual sub-systems across different physical locations and organisations. I go on to propose a simple method to keep track of individual subsystem locations and their high-level functionality. I also propose how the functional model can be represented as a negative-feedback control system. I then examined the development and implementation of RCS systems and propose that these systems go through two unique V-cycles, a generic product development V-cycle (by suppliers) and a specific application V-cycle (by operators). I propose that this results in the whole system lifecycle being covered by a closed-loop W-cycle that shows the complete development and procurement process for most metro railway RCS systems. I go on to propose that a more complex process is often required on mainline railways where there are often multiple sub-systems that are procured from separate suppliers and must be integrated into a single system. I conclude with a study of different project delivery structures for RCS upgrade programmes and recommend a balanced system-centric structure.My conclusions are that RCS systems are critical to both the safety and performance of the railway and are complex systems of systems. They have clearly defined functional sub-systems that contribute to these two key criteria. Based on my findings, I suggest that a systematic approach to the development, as well as the deployment, of RCS is therefore vital in order to ensure successful development, delivery and integration of modern RCS systems, such as ERTMS, TMS & DAS.

“…Until now, the ATACS (Advanced Train Administration and Communications System) [5] in Japan already have been applied in practice. Besides, other radio railway systems such as the ETCS (European Train Control System) level 3 [6], the CTCS (Chinese Train Control System) level 4 [7] and the Automatic Train Protection and Block (ATPB) [8] system are also in development. On the other hand, the railway system belongs to safety critical system [9], and its software system belongs to SWSIL4 (software safety integrity level 4).…”

In the development of communication based train control (CBTC) system, while communicating with the control center, the train must be assigned accurately to the wayside network. In order to verify the rigor of this process, the specification is analyzed formally in this paper. After studying the system, the functional requirements are clarified firstly. Followed by the formal specification is established by VDM explicitly, including the state variables and top-level operations. Then the internal consistence of the formal specification is validated, which can prevent potential runtime errors in software program. Lastly, in order to ensure that the specification satisfies requirements, the requirements are transformed to corresponding inference rules, and then validated by discharging proof obligations. The work in this paper indicates that if the software system of a CBTC system is designed strictly in accordance with the specification, it will be internal consistent with high reliability, and satisfy the design requirements.

The railway signaling system is one of the key subsystems in railway systems to ensure the train operation efficiency and safety. It is a complicated system. However, the railway signaling system is not independent in railway systems. In this paper, five parts of the railway signaling system with their features and the relationship are described in detail. Firstly, the core system of the railway signaling system is designed and developed. Re-design is carried out for the application of the core system for the specified rolling stocks and lines. The safety of the core system and the applied system needs to be assessed. Finally, a complete simulation system should be built for testing, installation, maintenance and the technique upgrading of the systems. This paper helps people to get a deep understanding about the functions, design and development, applications and simulation of railway signaling systems.
