DescriptionA tramway junction.JPG |
English: A tramway junction in Helsinki. A tramway junction can be radio-controlled by a tram driver. The junction locks in the position the driver wants, and can even give information on its position to driver. The junction might be operated manually in case of power failure. The junctions can be heated to avoid freezing in cold regions. The picture shows that the tracks are typically embedded to road. Therefore special brush cars or trucks regularly clear the groove from sand, leaves, snow, and litter.
Русский: Трамвайная стрелка с радиоуправлением в Хельсинках. Стрелка переключается в требуемую позицию водителем трамвая и выводит информацию об этом на пульт управления. В случае отсутствия электроэнергии стрелку переводят вручную; в регионах с холодным климатом устанавливают системы обогрева от снега и льда. На фото видно, что рельсы утоплены в дорожное покрытие, поэтому специальные машины регулярно очищают пути от песка, опавших листьев, снега и мусора. |
