Technology

ETCS is the core signalling and train control component of ERTMS, the European Rail Traffic Management System. ETCS continuously calculates a safe maximum speed for each train, with cab signalling for the driver and on-board systems that take control if the permissible speed is exceeded. For ETCS trackside equipment and train borne systems need to be standardized according to the different ETCS levels.

Thales offers a complete portfolio of ETCS solutions for turnkey projects in the same way as for green field or brown field installations. Not only the obvious areas, such as trackside equipment or train borne installations are covered. At the same time we will take care of other horizontal areas such as cyber security or special functionalities besides international specifications. For example DAS, ATO, IP-based radio communication and advanced diagnosis.

ETCS Level 1

ETCS Level 1 can be easily superimposed on the existing national signalling system and provides cab signalling. Movement authorities can be granted through fixed and switchable Eurobalises. They also send route data to the on board unit. With the received data the maximum speed as well as the breaking curves are calculated at any time. Additionally to Eurobalises it is possible to implement EuroLoop (loop infill) or a radio based solution (radio infill) which continuously transmits data over a longer distance.


ETCS is installed trackside and train borne. Data is exchanged by spot transmission from track to train via ETCS balises.

ETCS Level 2

ETCS Level 2 is a radio based system which displays signalling and movement authorities in the cab. The train is continuously sending data to the Radio Block Centre (RBC) to report its exact position and direction. Eurobalises are used as passive positioning beacons. Trains refine their position with additional sensors such as accelerometers, odometers or radar.


Extended level 1, with ETCS data transmission continuous by GSM-R. On the trackside a RBC controls all train movements in the covered area.

ETCS Level 3

ETCS Level 3 is a fully radio based system without any trackside equipment. The Radio Block Centre (RBC) receives positioning of each train continuously and calculates smallest possible train distances at any time. Therefor the track is no longer separated in fixed blocks but split into “moving blocks”. At the same time it is vital that trains guarantee their integrity as there is no trackside equipment available to provide this information. ETCS L3 is currently still under standardization.


Trackside equipment disappeared. Train-location and -integrity do not rely on trackside equipment (signals, track circuits or axle counters) but are handled by train and RBC.

Customer focused innovation for business performance

Our onboard and trackside systems continuously control your train movement with minimized headway in order to achieve higher performance, improved track utilization and greater passenger service frequency. They are based on the ERTMS system that is successfully deployed worldwide. 

Maximizing revenue through interoperability

Harmonizing train control is the key to foster railway transport system competitiveness in Europe. ETCS implementation will increase railways operators’ operational performance through enhanced capacity and speed, enabling them to expand their share of freight and passenger business in an expanding market. ETCS enables to strongly decrease the traffic congestion caused by persistent bottlenecks, missing links and lack of interoperability.

Increasing Safety and Security

Safety is the primary business of Thales. All of our solutions focus on ensuring the safe operation of your railroad. Our Train Control solutions provide full Automatic Train Protection capability based either on the ETCS standards or the, well-proven, LZB system.

Improving Customer Services

By integrating our ATC (Automatic Train Control) systems with modern interlocking technology and advanced management operation centres, the customer is able to offer attractive services for rolling stock operators (the transportation of goods) as well as for passenger traffic (economically attractive services to a liberalized market). The Thales solutions automate the daily work of all personnel of the railway companies to continuously improve the overall performance of the system.
