How SNCF is using predictive analytics to keep trains running

French national train operator SNCF is using the industrial internet with sensors on trains and tracks to reduce failures and improve the reliability of trains, signals and tracks.

A combination of technologies are coming together to make it possible for the train company to connect its trains on to the industrial internet. First, sensors are getting smaller and now consume less energy, which is important as it is not always possible to be close to an electrical supply. In some cases,  battery life can extend to 5 years.
