The railway industry continues to be a hotbed of innovation, with activity driven by the need for high efficiency, reduced emissions and enhanced passenger experience, and growing importance of technologies such as automation, advanced train control and signalling, and smart monitoring and surveillance systems. In the last three years alone, there have been over 46,000 patents filed and granted in the railway industry, according to GlobalData’s report on Cloud in Railway: Centralised train control system.

According to GlobalData’s Technology Foresights, which uses over 9,000 patents to analyse innovation intensity for the railway industry, there are 10+ innovation areas that will shape the future of the industry.

Centralised train control system is a key innovation area in cloud

The centralised traffic control system (CTC) is an integrated solution to control and manage the railway traffic from a single location. The system utilises a centralised train dispatcher that controls wayside station interlockings and train movements, improving the traffic regularity and optimising the railway operation within a designated territory.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 10+ companies, spanning technology vendors, established railway companies, and up-and-coming start-ups engaged in the development and application of centralised train control system.

Key players in centralised train control system – a disruptive innovation in the railway industry

‘Application diversity’ measures the number of different applications identified for each relevant patent and broadly splits companies into either ‘niche’ or ‘diversified’ innovators.

‘Geographic reach’ refers to the number of different countries each relevant patent is registered in and reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.
