Abstract
The railway is a complex technical system of systems in a multi-stakeholder environment. The implementation of digital technologies is essential for achieving operational excellence and addressing stakeholders’ needs and requirements in relation to the railways. Digitalization is highly dependent on an appropriate digital infrastructure provided through proper information logistics, whereas cybersecurity is critical for the overall security and safety of the railway systems. However, it is important to understand the various issues and challenges presented by governance, business, and technical requirements. Hence, this paper is the first link in the chain to explore, understand, and address such requirements. The purpose of this paper is to identify aspects of distributed ledgers and to provide a taxonomy of issues and challenges to develop a secure and resilient data sharing framework for railway stakeholders.
Highlights
IntroductionThe operations of freight as well as passenger services have strict requirements of reliability, availability, maintainability, and safety
The results are based on the data collected and analyzed through the literature surveys, workshops, and discussions, and questionnaires with various industry partners representing different aspects of railways stakeholders such as the regulating agency, the manufacturers, the operators, and the service providers
The results are comprised of two sections: (i) properties that have been identified to be of consequence for the use of a distributed ledger to create a secure, distributed data sharing environment, (ii) issues and challenges to be addressed for creation of a data-sharing environment
Summary
The operations of freight as well as passenger services have strict requirements of reliability, availability, maintainability, and safety. The consistency of railway transport in terms of schedules and availability is affected by various factors related to the operation and maintenance of the overall infrastructure and the support of various railway stakeholders. The current segregation and structure of the railways has its roots in the deregulation of the railways, which started in Europe in the 1980s with the intention of ensuring the best use of public funds and to create a sustainable environment within economic and legal requirements [1]. Deregulation over a period helped to bring in a common European market for services, material, equipment, and standardization in the railways to set railways as the preferred mode of transport [3]
