For the support of the ITCS system of the railway operation in general and of the different maintenance areas of Fenoco, there are different communication systems for the transmission of voice and data, based on different platforms and standards considered cutting edge technologies.
It is a standard defined by ETSI (European Institute of Telecommunications Standards) as a mobile digital radio system that unifies several alternative interfaces. This system is made up of several devices that allow voice and data communication between all actors of the railway operation, CTF, train masters, maintenance personnel, etc.
As end devices for the user, portable radios, mobile radios, base radios and RTPS are available. The management of the system is done through a redundant central node together with the different base stations installed along the railway track, which store and process the calls or data generated daily in the operation. In addition, all voice processes are stored in a recorder that is part of the management node. These records are used to follow-up and control of the communication protocols and investigation in case of incidents.

This system is used for locating and recognizing trains from the beginning of the route to their arrival at their destination, constantly updating and checking information with the devices located in each railway station.
As a transportation network, Fenoco installed more than 200 km of fiber optic in the section between La Loma (Cesar) and Ciénaga (Magdalena), which works in a redundant manner by having a second fiber backing path , management and traffic is carried out through redundant layer 2 switches installed in the railway stations, changeover booths and Data Center, resulting in a network in rings to avoid interruption in data transmission.
