being supplied by the mine's existing transmission supply from BC Hydro. Germany The German Federal Ministry for the Environment is building a network of overhead wires along the autobahn for diesel-electric hybrids, allowing trucks to cruise on electric power. A short test stretch has been built on an Armybase in Brandenburg, with longer routes in Hesse and Schleswig-Holstein planned for 2018. The Test in Schleswig-Holstein has started on 1 June 2019 and in Hesse on 7 May 2019. A further Test is planned in Baden-Württemberg. Italy Trolleytrucks were used by the AEM electric utility company of Milan, Italy to supply construction materials and service to the San Giacomo Dam (constructed 1940–1950) and the second Cancano Dam (constructed 1952–1956). The two trolleytruck lines in the Valtellina valley that helped to build then supply the dams along the Spöl river were used from 1938 to 1962. Namibia The Rössing Uranium Mine in Namibia installed a trolley assist system around 1986. The diesel electric drive Komatsu 730E dump trucks were converted at that time to use trolley power assist for the climb out of the mine to the crusher. The fleet numbered more than 10 vehicles as of 2001. South Africa Trolleytrucks were introduced to the Palabora copper mine in South Africa in 1980. The South African Iron and Steel Industrial Corporation (ISCOR) installed a trolley power assist line for diesel electric trucks at its Shishen mine in March 1982. Afterwards the company also installed a trolley power assist system at its Grootegeluk coal mine in Lephalale, South Africa. ISCOR (now known as Mittal Steel South Africa) is the largest user of trolley power assist trolleytruck systems in the world. Soviet Union, Russia, Ukraine Many cities in the Soviet Union operated trolleytrucks. The MAZ-525 truck model was converted to a trolleytruck design in 1954 in Kharkiv, Ukraine. The Kharkiv experiment with trolleytrucks was stopped because of disadvantages. Nowadays trolleytrucks operate in several cities in Ukraine such as Donetsk and Sevastopol as well as cities in Russia such as Bryansk and Saint Petersburg. One type, the KTG-1, is made for service and repair of the urban trolleybus vehicles; while another, the KTG-2, is used for transporting goods. Sweden The first public electrified motorway opened in Sweden on 22 June 2016 on a stretch of European route E16 near Gävle, allowing hybrid and battery electric Scania lorries to run from overhead wires. Switzerland Trolleytrucks were
