Schalke Marks Two Decades of Locomotive Sales to Codelco
The 130-mt units were designed to Codelco’s specifications and provide a maximum speed of 60 km/h, powered by four 600-kW traction motors that generate maximum tractive force of 256 kN. The locos’ AC technology allows for electro-dynamic braking down to a complete stop, eliminating the need for mechanical brakes in normal operation and reducing wear on rails, wheels and other components.
All of the locomotives are equipped with Bombardier’s INTERFLO 150 train control system, an advanced traffic control system well-suited for operations in underground mining conditions. The system provides for unmanned train operations as well as remote-controlled loading and unmanned unloading, can accommodate a mixture of automatic, semiautomatic and manual operations, and allows for simultaneous operation of both production and auxiliary trains.
All 22 locomotives were sold to Codelco via Ferrostaal, a German trading and service company. Ferrostaal Chile, a subsidiary of the German parent company, has a maintenance contract for all locomotives delivered to Codelco. In a cooperative program involving Schalke, Ferrostaal and Codelco, the first major overhauls for the 72-mt locos, as well as the original eight 130-mt units, will take place in 2015 and 2016, allowing the locomotives to be fitted with current-generation gearboxes, traction motors and traction converters.
