In May 2001, Bombardier Transportation acquired Adtranz from DaimlerChrysler, and became by many measurements the Western world's largest rail-equipment manufacturer. The takeover was approved by the EU Competition Commission subject to a number of minor clauses including the divestment of Bombardier's stake in Adtranz/Stadler joint venture Stadler Pankow (sold to Stadler Rail), and an agreement to retain Kiepe Electric as a supplier, and ELIN as a partner for a number of years after the acquisition. The addition of Adtranz made Bombardier a manufacturer of locomotives along with its existing product lines of passenger carriages, multiple-unit trains, and trams. With the acquisition of Adtranz, Bombardier also gained competence in the electrical propulsion components business.
