[PL] Stadler and Mermec: Guardia ETCS officially certified for the first time

Stadler’s ETCS automatic train protection system, Guardia, has been certified for use in Poland by Koleje Mazowieckie (KM)’s FLIRT trains. While the train control system is currently being homologated for use in several other countries, including Switzerland, Stadler highlights that Poland is the first country where the process has been officially completed.

Guardia is a high-end ETCS-based train protection system that is being manufactured by the Stadler-Mermec joint venture, AngelStar. On 18.06.2020 Stadler officially announced the successful homologation of the ETCS baseline 3.4.0 system for use by regional operator Koleje Mazowieckie’s five-car FLIRT EMUs, which are equipped with the system.

According to Stadler, the homologation fully complies with the European Union’s “Commission Regulation 2016/919 on the technical specification for interoperability relating to the ‘control-command and signalling’ subsystems of the rail system”.

The FLIRT trains which will be operated in the Polish region of Mazovia are equipped with a GUARDIA version according to the ETCS baseline 3.4.0 and the ETCS levels 1, 2, and NTC (National Train Control). The safety system change from ETCS to the Polish national system SHP and vice versa is fully dynamic, allowing the trains to operate seamlessly without stopping for the safety system change.

The launch of Guardia was first announced as part of the ongoing production of FLIRTs for Stadler’s Swiss client, BLS. In fact, the signalling division of the Swiss corporation is already in the process of homologating its system to several other countries at present:

 “We are very pleased about the first homologation of GUARDIA for regular operations while the homologation processes in nine additional countries are proceeding positively. Together with AngelStar, we continue to work on multiple projects across Europe. ( … )” – Alexandre Grêt, CEO of Stadler Signalling
