The current rail infrastructure is to blame for about 50% of all train delays. Unreliable signal systems, maintenance and construction work are factors to be considered here.

Rail infrastructure is facing rising demands and is expected to handle more trains as well as faster trains. The infrastructure is under pressure, and if operators wish to deliver sufficient capacity, a focus must be set on optimizing the rail infrastructure. Modern, healthy and sturdy railways with reliable signal systems are more likely to be able to support more traffic without causing higher delay rates.

By continuously monitoring problematic rail sections, infrastructure operators are enabled to predict behaviour. This can make it possible to both adapt railway capacity and minimize needs for periodically monitoring the rail using traditional methods, that include several workers, specialized equipment and possibly track lockouts.

Another factor that can cause delays and longer travel times is construction work, which is needed to upgrade the rail infrastructure. When construction work is conducted close by the railway, two scenarios are possible:

  1. the allowed train speed is heavily reduced. Typically, trains must pass the construction site at a speed of 40 km/h on a rail, that can handle 120 km/h.
  2. the rail gets closed. Passengers must take buses to get past the rail in construction or the train might need to take an alternative, longer route.

Sometimes, track lockouts are impossible to avoid. And sometimes, it’s a precaution, because no known methods are sufficient to assure a safe passing for the trains.

Real-time monitoring directly on the rail sleepers provides safety managers with an insight into the actual state of the railway. This makes it possible to either adapt the allowed speed on the railway or to allow trains to pass in situations, whereas this would be impossible using traditional methods.
