The Alstom Metropolis BM4 (Bucharest Metro 4th generation) is a family of metros designed for the Bucharest Metro, with 13 six-car trainsets currently built by Alstom at the Taubaté, Brazil plant as of 2023.
History[edit]
The trains were ordered on November 3, 2020,[1] after more than a year of tendering with Alstom, CAF, Hyundai Rotem, Metrowagonmash and a consortium of Astra Vagoane Călători and CRRC Qingdao Sifang being the bidders.[2]
This order comes after the failed 2015 framework agreement order for 51 trains initially signed with CAF, which was cancelled due to corruption allegations between Metrorex and CAF during the tendering process.[3]
The contract signed with Alstom consists in 13 trains to operate on the first phase of line M5, with an additional 17 units as an option, which are destined for the second phase of line M5 between Eroilor and Piața Iancului.
The units would be built at Alstom's plant in Taubaté, Brazil, which was expanded in November 2022 in anticipation of the contracts signed in Bucharest, Taipei, São Paulo and Santiago de Chile.[4]
Deliveries were expected for the summer of 2022, though multiple delays were encountered by Alstom during the production of the BM4 pushing the date to April 2024, ultimately leading Metrorex to apply penalties of upwards of 20 million euros.[5]
Alstom cited the COVID-19 Pandemic and the war in Ukraine as the main reasons of the delays due to supply chain issues caused by these events, alongside a 50 meter S-curve near the Romancierilor station instead of a 100 meter S-curve specified in the requirements, leading to Metrorex rejecting the prototype and having Alstom to redesign the carbodies. Ultimately in January 2024, Metrorex accepted the revised version of the BM4 in the form of the unit 1402-2402 "Giurgiu", giving the greenlight for the series production.[6][7]
Delays are also caused by the shipping system. Alstom hasn't found any company to ship the BM4s directly to Romania via the Port of Constanța, due to the possible threat of Russian mines being present in the Black Sea, leading Alstom to ship the trains to the Port of Hamburg by sea, and by road to Bucharest.[8]
Design and features[edit]
The BM4 reuses and refines the Vagn 2000 basis for the design, introduced with the Bombardier MOVIA 346 trainsets and later refined with the CAF Inneo BM3 trainsets. The front is inspired after the final Bombardier MOVIA design language before Alstom's takeover in 2021, resulting in a similar front to Singapore's MOVIA R151. The livery is similar to the CAF Inneo BM3, though with an orange stripe signifying their use on line M5.
As usual the trainsets are configured in a R1+MP1+M1+M2+MP2+R2 formation, with R meaning Trailer Car (ro. Remorcă), MP being Power Car with Shunting Pantograph (ro. Motor Pantograf) and M being Power Car (Motor)
It includes several upgrades. Passenger ventilation is now powered by six large forced ventilation units with refrigeration, alongside the enhanced security with CCTV cameras, better passenger information with LCD displays, larger windows and stainless steel seats. The cabs can be easily dismantled for driverless operation in the future.
