About us


Last week, the first locomotive of the new SALi (South American Light Loco) series successfully was tested at STADLER´s working site in Valencia. The on-board generators of this locomotive series came from our partner VEM Sachsenwerk. The XD2T device tailored for traction applications from our company ensures their excitation and monitoring. Commissioning was accompanied by one of our engineers. According to information from STADLER, the SALi, which was designed specially for mountain use, is the first locomotive of an European manufacturer in Bolivia. With this locomotive STADLER has made an important step on the way to the Latin American market. We wish the best success!
