“…Increasing demand in railway networks requires the replacement of GSM-R with FRMCS that provide a higher QOS and capacity of data transmission. It must be able to guarantee safety requirements and forward, as well as backwards interoperability [1], [2].…”

“…One candidate is Long Term Evolution-Railway (LTE-R), which is based on 4G protocol; however, there is reason to hold off on implementing a new 4G system due to the imminent availability of better 5G networks. As a consequence, there is greater support from the International Union of Railways (UIC) to use a flexible 5G system, relying as well on other technologies [2].…”

The development of the European Railway Traffic Management System (ERTMS) throughout Europe over the last two decades to remove obstacles to providing an interoperable railway network has been facing several challenges. This study briefly highlights several of these challenges by analysing the current architecture of ERTMS and main concerns such as its implementation, the interoperability of communication, formal methods, hybrid ERMS (Level 3), safety, and human factors. This study has taken a systematic approach to data collection and analysis through a review of the current literature. The studies examined illustrate that it is necessary to reduce the number of components in order to pivot the system toward mobile equipment, autonomous trains, and decentralised communication. In the area of formalisation, every supplier and responsible party conducting modelling and testing of the system uses a different tool. Here, we conclude it would be appropriate to develop a robust and reliable tool for modelling, formalisation, testing and the validation of critical safety systems in the railway industry according to its particular specifications and functionalities, e.g. for ERTMS L3, including moving block, virtual coupling, and Automatic Train Operation (ATO). To bridge gaps between human operation and new technologies, reduce human error, and increase performance in the railway industry, a stronger emphasis on the development of employees' skills with new technologies is highly recommended. In order to build upon previous investments in ERTMS and to guarantee backwards and forwards interoperability, it is necessary to exploit hybrid solutions and to gradually update the current systems.

“…If we even include all the events leading to loss of message sequence (such as the presence of coverage holes and tunnels without radio facilities inside, etc. ), the loss probability may raise up to 7% as indicated in [19]. However, the positions of tunnels and coverage holes are known in advance so that connection failure can be predicted and properly taken into account for train management operations.…”

“…In the 3InSat project [18] within the framework of the European Space Agency (ESA) Advanced Research in Telecommunications Systems (ARTES) 20 programme, by means of an experimental campaign, we have investigated on the possibility of achieving acceptable QoS on public terrestrial networks integrated with satellite [8,19] as the economical feasibility of this approach. Considering that in the short/medium-term radio bearers provided by public networks will offer best-effort services, in [18], we also made evidenced that the satellite is an important component to achieve the required QoS levels.…”

End-to-End Delay Model for Train Messaging over Public Land Mobile Networks

Abstract:Modern train control systems rely on a dedicated radio network for train to ground communications. A number of possible alternatives have been analysed to adopt the European Rail Traffic Management System/European Train Control System (ERTMS/ETCS) control system on local/regional lines to improve transport capacity. Among them, a communication system based on public networks (cellular&satellite) provides an interesting, effective and alternative solution to proprietary and expensive radio networks. To analyse performance of this solution, it is necessary to model the end-to-end delay and message loss to fully characterize the message transfer process from train to ground and vice versa. Starting from the results of a railway test campaign over a 300 km railway line for a cumulative 12,000 traveled km in 21 days, in this paper, we derive a statistical model for the end-to-end delay required for delivering messages. In particular, we propose a two states model allowing for reproducing the main behavioral characteristics of the end-to-end delay as observed experimentally. Model formulation has been derived after deep analysis of the recorded experimental data. When it is applied to model a realistic scenario, it allows for explicitly accounting for radio coverage characteristics, the received power level, the handover points along the line and for the serving radio technology. As an example, the proposed model is used to generate the end-to-end delay profile in a realistic scenario.

The European train control system employs GSM-R for communications between trains and the command/control centers. GSM-R technology is quite old and will be replaced in the near future by other technologies offering less expensive solutions, especially for regional and local lines. This article investigates a new telecommunication solution based on multi radio bearers using cellular and satellite public networks as an alternative to the deployment of a dedicated infrastructure. A test campaign on a 300 km of rail line (about 10,000 km of tests) has been carried out to evaluate the performance of cellular and satellite networks in a railway environment. Test trial results presented and discussed in this article have been used to assess the performance of a multipath TCP protocol to effectively support multi-bearer communications. A discussion of the economic benefits and the potential industrial implications of the proposed solution concludes the article
