Turnout is a big family, the most common is the ordinary single turnout. It consists of switching points, connecting part, frog and guard rail three units. Derailleur including basic rail, rail and turn sharp mechanical rut. When locomotives from A into B shares Road Track, manipulate mechanical derailleur so sharp track mobile location, a snug basic tip rail track 1 track 2 tip from basic track 2, which had opened the B shares Road, A shares closed the mine road transport tub manufacturer, locomotives transition into the connecting section curves along the guide rail to the frog and guard rail unit. This unit includes a fixed frog heart, wing rail and guard rail, the role is to protect the safe passage of the wheels of the two strands of the cross rail lines. Turnout harmful way to solve the fundamental space, of course, is to eliminate harmful space. Since the general turnout can not, we must develop a special turnout - Activities heart turnout. The main activity is characterized by heart rail frog heart can track plates move. When we want to open a certain direction Track mine shipped tub, frog heart activity center rail track on the same direction with the opening of tight mine wing rail transportation company tub, separate from the other wing of the rail, so to purchase mine transport carts, harmful space ordinary turnout would not exist. Practice has proved that the elimination of harmful turnout space, driving more smoothly, the speed limit is too small turnout, which is particularly suitable for large volume, high-speed train lines need to open lines to use.
