Local control area

from Wikipedia, the free encyclopedia

A Nahbedienbereich or Nahstellbereich is in railway operations a stellwerk serviced parking district, which can be temporarily released for local control.

If necessary, the operator responsible for shunting in the local control area is passed on from the signal box staff to the on-site shunting staff . The shunting personnel can independently set the route and maneuver there on sight . For this purpose, control points are installed on site (e.g. shunting desk, shunting interlocking, control booth, control column, control stand) with which the turnouts can be operated when the local control area is switched on .

Local control areas are mainly used in remote-controlled interlockings and can be set up both in side tracks and in main tracks . When the local operating area is switched on, the side protection to the area operated by the interlocking must be ensured by means of locked safety switches. No train or shunting trips can take place between the local control area and the interlocking area.

However, local control areas must not be confused with shunting areas with locally operated points or electrically localized points (EOW) , since the responsibility for driving operations always rests with the shunting personnel.

service

After a telephone agreement between the parties involved, the shunting personnel can request local operation at the local control point. The signal box staff then switches on the local control area. All switches of the border-flank protection run automatically and are locked in the protective layer.

Depending on the location, the electrical points can be centrally z. B. from a switching interlocking or decentralized with columns at each turnout. In some older relay interlockings , central control points were used with which shunting routes could be set by a local operator. For this purpose, the track vacancy detection system and the blocking signals of the local control area were used, if available . In modern systems, the points are usually set individually by means of setting columns. So that the driver can recognize the position of the switches, the switches are equipped with switch signals. Since there is no shunting route, the main and blocking signals are switched off and show identification lights .

After completing the shunting work, the shunting staff returns the local control area to the signal box staff with a ready-made operation. Train and shunting routes can again be set by signal box personnel.
