What do you mean by track circuiting?
What do you mean by track circuiting?
A track circuit itself is an electrical system that detects the absence of a train on a section of track. This information then helps the signalling system know if it’s safe for another train to proceed.
What is the interlocking system?
An interlock is a feature that makes the state of two mechanisms or functions mutually dependent. It may be used to prevent undesired states in a finite-state machine, and may consist of any electrical, electronic, or mechanical devices or systems.
What is a track circuit block?
Track Circuit Block, commonly abbreviated to TCB, is a method of working between signalboxes and within a box’s control area. TCB relies upon an area’s running lines being track circuited throughout, thus giving proof of whether or not a section is occupied.
What is geographical interlocking?
The geographical interlocking idea is, for any given layout, the signalling is split into a number of standard blocks consisting of points, signals, track circuits, and ground frames etc. each as an individual element.
What is interlocking in railway signalling?
In railway signalling, an interlocking is an arrangement of signal apparatus that prevents conflicting movements through an arrangement of tracks such as junctions or crossings. The signalling appliances and tracks are sometimes collectively referred to as an interlocking plant.
What is track bonding plan?
The majority of running rails are used to form track circuits to provide a means of proving the absence of trains. The General arrangement is that a low power signal is transmitted from ans end of the track circuits, along one rail, to a receiving device.
What is interlocking system in railway?
Interlocking is a railway signal apparatus that prevents conflicting movements of trains through an arrangement of tracks such as junctions or crossings.
What is interlocking short answer?
Explanation: interlocking means the irregularities interlocked with each other of two objects surface when they are in static ( standing straight without moving).
How long is a track circuit?
The length of the Single Rail Track circuit is permitted up to 500 meters. The maximum permissible length of the Double Rail Track circuit is 2,300 meters. The cable lead Resistance at the Relay end shall not exceed 12 Ohms irrespective of the length of Track circuits.
What is interlocking explain with an example?
The definition of interlock is to be linked or joined with something by having parts overlapping, criss-crossed or fitted together. When you hold hands with someone and you twist and wind your fingers together, this is an example of when you interlock your hands.
What is railway bonding?
2.7 “Rail-bond” means an electrical connection across a rail joint between consecutive lengths of rails. It is also called a “Longitudinal bond’. 2.8 “Rail length” means a continuous length of rail with or without welded joints but with no fish plate joints.
What is Earthing and bonding in railway?
Bonding and Earthing is an essential part of the 25kV AC, Traction System. Bonding is a solid electrical connection between two or more conductors or non- current carrying metallic parts i.e. traction mast, structure, support and rails.
