The Barcelona metro has yet again placed its trust in Ingeteam, and is set to install the regenerative braking system developed by the company in its lines 3 and 4. At the end of last year, Transportes Metropolitanos de Barcelona (TMB) already installed this system in suburban line 9, so that this new contract confirms the validity and effectiveness of Ingeteam’s solution.
This technology makes it possible to recover up to 30% of the braking energy of the train, in order to reduce CO2 emissions, and to lower the operator’s energy bill (TMB). The Ingeteam contract covers the installation of two units; one for line 3, one of the oldest lines in Barcelona, comprising 26 stations over an 18.4 km route, and the other for line 4 comprising 22 stations over a 17.3 km route. TMB uses the energy recovered at its own facilities, for indoor station lighting, escalators, etc.
After a four year development phase and a 3 million euro investment in R&D&I, Ingeteam’s Traction Division has developed this regenerative braking system that is ideally suited to LRVs, trains and tramways, due to their frequent stopping requirements, which is precisely when the system recovers energy.
