Most companies which responded to us were relatively young (2-5 years old). They were all already engaged in at least one other industry, most commonly manufacturing, but automotive and aerospace were also popular responses. When asked what they could offer the rail industry, suppliers cited many of the applications of this technology we have already described in this series, such as asset management, improving safety, and improving the customer experience. One company reported they were developing scalable mobile data solutions to match rural and city performance which would improve coverage across the rail network. Other interesting applications in development included intrusion detection devices and behavioural analytics.
