Clearsy obtains a new SIL2 certification

ETCS Baseline 3 application certified SIL2

Clearsy had already announced the SIL2 certification of the display screen developed by Centralp. The ETCS Baseline 3 application developed by Clearsy is now also SIL2 certified by Certifer (Independent Safety Assessor).

This new console fully meets the requirements of the reference document : SUBSET 091 - Safety Requirements for the Technical Interoperability of ETCS in Levels 1 & 2, version 3.4.0, dated 01.12.2015 (section 7.2.1.5) and also the informative document: the SUBSET 118 Functional Safety Analysis of ETCS DMI for ETCS Auxiliary Hazard, version 1.4.0, dated 20.06.2016 (section 6.8.1.2).

The SIL2 level is also confirmed in an opinion letter by the Europan Railway Agency (ERA) issued on 28 January 2015, confirming the tolerable hazard rate (THR) and asking for updates of the previous version of those SUBSETs.


Risk reduction

These provisions thus reduce the risk of the operator not seeing or misinterpreting the messages on the screen, and of commands not being taken into account.
 

For other applications, the integrator will be able to easily add its application part based on the already SIL2 certified basic principles of the console (via a configuration file), following a list of recommendations already approved by certificate (exported constraints).
 

Deutshe-Bahn

Talgo, a major Spanish manufacturer, has recently trusted this SIL2 DIM2 resulting from the Clearsy / Centralp partnership, and is developing a Train Control and Monitoring System (TCMS) application; the console will equip the trains of the Deutshe-Bahn, a German operator known for the reliability of its systems.
