Company History

Whole History

ČD - Telematika has continued its focus on providing services and maintenance of ŽTM for Správa železnic. In April 2020, however, Správa železnic announced to ČD - Telematika its intention to secure this activity with its own resources and invited ČD - Telematika to start negotiations about the sale of the part of the plant providing this activity. ČD - Telematika was therefore intensively engaged in negotiations on the form and conditions of the transaction for the rest of the year. These negotiations continued in 2021.

The crucial project and new responsibility for the period of the next few years to come is the delivery of the mobile part of the European Train Control System ETCS for České dráhy and ČD Cargo. In the course of 2020, two traction vehicle prototypes were successfully completed for the ČD Cargo contract, and the series installation is gradually beginning.

In the area of construction, the successful implementation of the contract to secure the Březno tunnel on the Lužná u Rakovníka – Chomutov route using the innovative Lidar technology for our partner AŽD was realised. At the same time, several other orders for the reconstruction of route sections and infrastructure were implemented within the relocation of optic-fibre cables, for both SŽ and ČD – Telematika’s own optical infrastructure.

In 2020, the Company also continued with GSM-R construction projects, the contract for system integration of a new Technical Passport Infrastructure (TPI) and delivery of new telephone exchanges for Správa železnic. The year 2020 brought a further shift towards resolving an issue regarding Správa železnic and ČD land for ŽVPS line purposes. Geometric plans have been drawn up for most of the questioned land, and servitudes have already been set up for some of them between ČD - Telematika, Správa železnic and ČD. ČD - Telematika’s goal was to have this issue resolved by the end of 2020, however, due to the pandemic situation the project was delayed and will be completed during 2021.


ČD - Telematika, ALSTOM Belgium and the ADŽ consortium won a contract for the mobile part of the European ETCS train protection system delivery for ČD Cargo. ČD-T will equip 78 locomotives of ČD Cargo in total – 31 locomotives of the 163 series, and 47 locomotives of the 363 series. Completion of the contract, totalling tens of millions of euro, is planned by the end of 2022. ČD - Telematika, ALSTOM Belgium and the ADŽ consortium also won a contract for the mobile part of the European ETCS train protection system delivery for České dráhy. ČD-T will equip 131 locomotives of České dráhy in total comprising the 162, 362, 162 WTB and 362 WTB series. Completion of the contract, totalling tens of millions of euro, is planned by the end of 2023.
