Construction track

from Wikipedia, the free encyclopedia
Construction tracks are separated from operating tracks by a guard maintenance disc (signal Sh 2)

Construction track (abbreviation: Bgl ) is a term used in railway operations. It describes a track that has been left to the construction service and is therefore not available for regular train operations. This means that no train journeys can be made on a construction track . A track can be declared a construction track by the responsible dispatcher by means of operating and construction instructions (Betra) after the preconditions have been met. This means that responsibility for vehicle movements is transferred to a “technical authorized person” for the construction project named in the Betra. These vehicle movements are carried out in the construction track as a shunting drive . If turnouts remain connected to the signal box in a construction track and if the changeover is permitted according to the rules in the Betra, then the dispatcher acts on behalf of the technically authorized person.

A construction track can be temporarily dismantled during the construction work or otherwise impassable. The track position can also change during construction work.

Company regulations

When driving on a construction track, special regulations must be observed. Basically, vehicle movements take place in a construction track as a shunting drive. When operating in accordance with the driving regulations of DB Netz AG (FV-DB), the maximum speed is also reduced to 20 km / h, and for slopes over 35 ‰ to 15 km / h. Trips into or out of a construction track are to be agreed separately between the technically authorized person and the dispatcher concerned. A shunting run that leaves a construction track may not turn into another shunting run or a train journey without a previous stop. Vehicles may not be moved in construction tracks. Turnouts located in the construction track may only be changed if this is permitted in the Betra.

Brakes

If a shunting in construction track by a shunter accompanied, it must, in contrast to regular shunting where this is required only in certain cases, an ever- air brake head are used. An air brake head is a device for the maneuvering attendant in order to bring the maneuvering department to a stop as quickly as possible in the event of danger by quickly venting the main air line , similar to a quick brake .

Parking of vehicles on the construction track

The parking of vehicles on the construction track is generally not permitted, unless it is permitted in the Betra . This may only happen if the surrounding main tracks are protected by mandatory flank protection .

Scope of closure and expansion of the construction track

Beginning of a construction track

Tracks on the free route may only be blocked between two train registration points, but in one area the blocking between two train sequence points may also be permitted. However, one Betra can be instructed to create a temporary train sequence position at any point. The blocked track may also be declared a construction track on smaller sections. The decisive inclination of a track to be declared a construction track must not exceed 40 ‰.

After the track is blocked, the responsible dispatcher declares it to be a construction track as soon as the technically authorized person has given their consent. Before this approval is given, the guard maintenance targets (Sh 2), guard advance signals (Vr 0) and flank protection devices must have been set up. It is required at the limit of Baugleises in both directions a guard support panel, and if - (also referred to as trains - it must be at a Zugfolgestelle or beyond the end of Baugleises at the end of the Baugleises blocking barrier rides can) towards the Baugleises a Wärtervorsignal in the braking distance in front of it .

Edge protection devices are required if the construction track joins a main track and shunting would have to be prohibited according to the other rules. In addition to switches and construction track barriers , the side protection can be created at least 10 m in front of the danger point or - if double light protection is required - an additional guard at least 50 in front of this or a signal indicating a stop; The guard maintenance disc located closer to the construction track can be the guard maintenance disc which delimits the construction track.

Like all other signals, the guard holding discs are usually immediately to the right - for journeys on the opposite track, immediately to the left - next to or above the track. They may only be set up on the track if the regular setup is not possible. In practice, this is usually done wrong. However, even with correct installation, the caretaker maintenance discs for the respective direction of travel would have to be removed or turned away, but not those against the direction of travel.

Before the construction track is lifted, the technical authorized person must have confirmed that the track is free and navigable, as well as the removal of the guard maintenance discs and construction track barriers.
