It can be installed at the insulating joints of the circuit boards; the red half is on the side of the rail insulated from the earth, the yellow half is on the side of the rail that is grounded.\u003c\/p\u003e\n\n\u003cp\u003e Under track-clearance conditions, a current flows through the electrical circuit: this is detected by the receiver, which transmits the information to the track relay, which is energized and produces the track-clearance information.\u003c\/p\u003e\n\n \u003cp\u003eThe presence of a rolling stock on the section causes a short circuit between the two conductors of the circuit, which are the two rails: the axle, being metal, is capable of conducting electric current. The short circuit interrupts the flow of current and the relay switches to the de-energized state, thus transmitting the information that the lane is occupied.\u003c\/p\u003e\n\n\u003cp\u003e The track circuit is the essential element of all safety equipment in stations and on all lines operated with the block system. In stations, where the electrically isolated components are closely spaced, the circuits are only a few dozen meters long; on open lines, the length can be much greater.\u003c\/p\u003e\n\n\u003cp\u003e The track circuit identification picket sees the inductive box on the opposite rail.\u003c\/p\u003e\n\n\u003cp\u003e Track circuit pickets are only found in station areas or depots and at major railway yards.\u003c\/p\u003e","brand":"TA Models","offers":[{"title":"Default Title","offer_id":42438246662369,"sku":"1356","price":2.9,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0626\/4340\/5025\/products\/dsc_0237_1.jpg?v=1644909180","url":"https:\/\/tamodels.com\/en\/products\/picchetto-limite-per-circuito-di-binario","provider":"TA Models","version":"1.0","type":"link"}
