1.FIZIKA lighting systems RAILWAY TRASNPORTA

The history of the use of lighting systems in rail transport began with a large spread of kerosene lamps in the 1860-1920 biennium. Then kerosene increasingly began to force gas and electricity, even though for a long time they have been used on the railway as a light-signal devices. Next in the process of technological progress we followed each other more and more complex and reliable systems light bars for railway transport. At the present stage, these systems have complex microelectronic device according to the high demands of our time.

Choke-transformers are installed at the boundaries of the block areas (in other words - at the traffic lights. Each track circuit must be isolated from the neighboring, which on rails hold special insulating joints.

When 4-digit A / B, as well as with 3-digit: the relationship between input, output routing and traffic lights at stations and between the input and predvhodnymi on stages is carried out not only by the code in the rails, but also a pair of wires between them. That's the difference. In your case, when two F at the World Cup is the code F, and one F at the World Cup is the code F, W and the input is lit in different ways (or a flashing F F + W). Because this pair upon receipt of the main switch at the input B under the current and on its side - without current. Hence switching contact me reading input.
