Alstom has retrofitted 36 Flirt EMUs of MAV-Start with the ETCS L2 designed to increase the speed and safety. The first 36 of 59 units have received the market authorisation license and are now back in passenger traffic equipped by the Atlas ETCS Level 2 train control equipment that meets the strict European requirements.
The entire project is scheduled for completion in September 2023, following a certification procedure involving extensive testing and verifications. Alstom was awarded this project through a public procurement process.
The primary purpose of the European Train Control System (ETCS) is to monitor the movement of trains and enhance the safety of rail traffic in various operational situations. The system continuously calculates warning, operating and emergency braking speed profiles, and also monitors the authorised speed for both the train and the track. In full supervision mode, it is practically impossible for a driver to mistakenly ignore a red warning signal. The enhanced ETCS Level 2 provides continuous monitoring via GSM-R. The ETCS Level 2 system improves traffic efficiency by allowing upgraded trains to circulate at higher speeds on lines where the track conditions allow, such as the Budapest-Székesfehérvár line, thus increasing the speed to a maximum of 160 km/h, compared to the previous speed of 120 km/h.
The first milestone of this complex project occurred three years ago, in January 2020, when Alstom obtained the conversion license for the Flirt EMUs. The production of the prototypes was followed by testing the specifications required the trains to run 250,000 km without failure. Alstom was authorised by the Railways Authority to carry out type-approval durability tests on 5 prototypes. In parallel with this process, pre-fitting started, followed by a final fitting in January 2022. The type-approval of the vehicle, which required an independent certification body to verify that the design, manufacture, and assembly of the vehicle complies with all European and national standards, was granted by the National Rail Authority in December 2022.
