Subsystem Control-Command and Signalling (CCS)

The control-command and signalling subsystem deals with the requirements of the TSI CCS and TSI SRT. 

In accordance with the Interoperability Directive 2016/797 (Annex II, 2.3/2.4), control-command and signalling comprises two subsystems, each of which deals with trackside and on-board aspects:

Trackside control-command and signalling (CCT) subsystem: all trackside equipment required to ensure the safety, management and control of the movement of trains authorised to run on the network.

Control-Command and Signalling On-board Subsystem (CCO): All on-board equipment required to ensure the safety, control and monitoring of the movement of trains authorised to run on the network.

Our employees have many years of experience with the associated testing and certification objects:

• Train control (e.g. ETCS, LZB, PZB, GNT and ZUB)
• Train radio: analogue and digital radio (GSM-R and FRMCS)
• Radio remote control
• Radio systems
• Automated driving (e.g. ATO)

Our experts in the two subsystems CCT and CCO combine in-depth expertise with years of experience in the certification business, giving you the decisive advantage for your new construction, conversion or expansion project. Our relevant references speak in favour of this.
