A special infrastructure of electrical traction equipment is intended to provide each train with the power it needs to move and make its journey, carrying people and goods from the station of departure to the station of arrival at the speed suitable to meet the time schedule. The electricity for the supply, transmission and control of train traction power is provided via:
- the substations, electrical nodes connected to a high-voltage network that are capable of transforming and converting high voltage into a form suitable for powering train controls and engines
- the catenary system, the set of overhead cables that distribute electricity over the railway line and transmit it to the trains by means of current-collecting devices known as pantographs
- the remote control equipment for the Operational Direction of Traction Power (DOTE), which allows to carry out from a central remote control post the opening/closing of the disconnectors and circuit breakers of a large portion of the network and to report any alarm signals to the DOTE post.
