5 Part of the introduction for FRS ersion 4 of ERRI/A200 The modularity of ETCS makes the railways capable of equipping their lines and trains to different levels depending on requirements to safety, performance and capacity, all based on cost benefit analysis. -ETCS is capable of being a train protection system without cabsignalling and even not fail safe -ETCS is able of being a train control system, fail safe and with cab signalling -ETCS is capable of enabling the railways to replace the lineside signals with cab signalling -ETCS is capable of equipping secondary lines, main lines and high capacity lines to different levels according to the operational needs -ETCS is capable of equipping single objects on a line which is not equipped.

6 Definitive Functional Requirements Specification FRS ersion 4.29: UNISIG classes the functional requirements into the parts mandatory, optional und trackside. The mandatory functions are based on the following criteria: uniform approach about the function function is necessary for fundamental Train Control function necessary for protecting passengers or goods leave-out of a function in ETCS could not be adequate prescription or be compensated by technical mean C11 Operational function: Shunting Emergency break applies when passing Supervised national speed or default speed Shunting movement Danger for shunting C12

7 Operational function: partial supervision (1) Start station of the train Driver selects partial supervision Static -profile Signal information received Partial supervision Full supervision C13 max of the train static -profile Operational function: Partial supervision (2) X sec For driver to acknowledge Partial supervision Emergency break will apply if driver does not acknowledge max of the line Full supervision Partial supervision C14

8 Operational function: Full supervision track train Static profile train distance C15 Operational function: Compatibility with existing Train Control/Protection System 1. National information received by national antenna 2. National front- end module translates national information in ETCS information 3. Protection of the train at least as safe as in national operation mode C16

11 Trainborne function: Release speed calculation (1) Static Profile of the train Possibility to release speed Safety distance overlap Dynamic profile release at released overlap release with overlap release max C21 Trainborne Function: Release speed calculation (2) New static profile received at the signal Signal clears in front of the train Release profile Existing dynamic profile overlap max after receiving new information C22

13 Special operations: Using multiple traction units Signal has changed to danger after the first traction unit has passed C25 Special operations: Using tandem traction units Advisory indication Normal indication MMI MMI Signal has changed to danger when the second traction unit passes C26

14 Protection functions: Emergency alert message to train (s) RBC can send emergency signal: - to all trains - to all trains in a selected area - to a selected train C27 Functions primarely related to RBC: Shunting area shunting movement supervised - no overriding of the shunting area - no overrun of max max for shunting Shunting area C28

16 Functional Interface Specification FIS The FIS guaranties the functional(logical) interoperability. Typical example: MMI For interoperability it is necessary, that the same information is visualized in one quality at the same time. The kind of visualisation is is not important. C31 FFFIS Form Fit Function Specification Typical Example of a FFFIS: Eurobalise The interoperability must be guaranteed at the air gap. C32

23 Basic principles The following functions are independent from the ETCS level of application: Method for Balise and radio data communication Method for train position message and registration Movement Authority Line description Special operation modes (shunting, etc.) Help-Functions (RBC-RBC changeover, ersion- Management) Dynamic - measurement By this it is possible for the onboard-system to upgrade (first equip level 1 and later level 2 )and to downgrade (level 2 onboard-system can run on level 1 tracks) the running level.

Authority to move is transmitted by Interlocking Radioblock-system ETCS ETCS The Movement Authority contains the Balise ID, distance, time- limit, overlap and target-speed ( in case of radio- transmission there are some more radio- specific elements) C48
