The tests, carried out in a laboratory train named TPH2, seek to ensure the correct functionality of the main composition systems developed in previous stages and to check the train’s traction with batteries and hydrogen.
In this first phase, Spanish energy firm Repsol will provide the infrastructure for generating renewable hydrogen and supplying the energy to power the train. In a second phase of the dynamic tests, Talgo and Repsol will validate the technology on a general track, first in the surroundings of Madrid and then in Extremadura.
The TPH2 test train consists of a Talgo Travca multi-system locomotive designed as a prototype vehicle capable of changing various gauges and adapting to various electrification voltages. It consists of five cars equipped with hydrogen fuel cell and battery technology and a laboratory car to control and analyze the test results.
Carlos Palacio Oriol, president of Talgo, said, “This is a fundamental milestone for Talgo and for the Spanish railway. The Vittal-One will facilitate emission-free mobility in the country, linking provinces, cities, and towns, as part of Talgo’s commitment to helping operators decarbonize the railway network.”
The Vittal-One dual hydrogen train is Talgo’s commitment to sustainable mobility in the short and medium radius. It is based on the Talgo Vittal technology platform for Cercanías and Media Distancia, adding hydrogen traction, which will be produced with 100% renewable energy sources. Therefore, it is the perfect solution to replace diesel traction and decarbonize those railway lines that are not electrified by a catenary.
The system is complemented by batteries that increase the power available when starting, taking advantage of the train’s braking to recharge, further proof of the sustainability of this type of train.
It will be designed to run at a maximum speed of 220 km/h in electric mode and 160 km/h in hydrogen mode. The hydrogen fuel cell will consume only 0.25 kg/km and give the train a range of 800 km without electrification.
