CAF develops an on-board vehicle system for track monitoring based on digital twin


The new system seeks to determine the state of the track through sensors installed in the vehicle during its normal operation. This is based on a physical model of the track that allows predicting the behavior of the vehicle in the face of various types of defects (corrugation, breaks, etc.) and automatic learning techniques (Machine Learning) to extract patterns for the automatic identification of defects and their magnitude.

The signal recorded by the sensors is divided into small sections. Advanced signal analysis techniques allow the extraction of patterns in each of them that are compared with results of a Digital Twin obtained under different types of defect. This comparison, performed with machine learning techniques, establishes the current condition of the track. Subsequently, a suitable visualization is generated that allows the maintenance provider to quickly determine which the most problematic track sections are and to establish a maintenance schedule.

Catenary-free trams, shaping the urban fabric


Catenary-free trams are ever more evident in the urban environment. This type of transport system can be more intrinsically inserted into the city, with low visual impact, and greater flexibility when it comes to design.

IDOM has designed the tram project for the city of Cuenca (Ecuador), declared a World Heritage Site by UNESCO. Catenary-free technologies have been used to preserve the architectural heritage of the city. Hybrid systems have been implemented in Spain, in Seville or Zaragoza, inserting them in urban centers, areas with limited space and green areas.

Another advantage of this type of tram is the savings in energy consumption, thanks to the electrical supply systems mounted on the ground. These allow energy from the storage device on the vehicle to be charged or discharged, while also using energy from regenerative braking. All in all, turning them into transport systems which are ever more sustainable and resilient.
