Railways around the world are moving towards digitalization to enhance their operations. The
integration of railway data with other transport modes data becomes a vital part of the next generation
of digital transport systems. One of the challenges for further digitization is data integration and
security. This situation remains a challenge across organization and industry boundaries. The
blockchain is a new technology that might have the potential for acting as an enabler for the data
integration and security challenge. In this paper a moderate literature review on the use of blockchain
around different industries, in particular IoT applications, and in the railway context has been
demonstrated. Opportunities and challenges that the blockchain technology can offer for the railway
industry has been outlined.
The paper has also looked at railway related blockchain current and potential applications. A simple
analaysis of the technology for the potential adoption rate has also been discussed. It was found that
the blockchain can offer a number of benefits including added security and decentralization, however it
will have a moderate technology adoption rate before it reaches it is transformative impact.
