Study Notes
Automatic Warning System
- Designed to assist drivers by indicating signal conditions and prevent accidents.
- Automatically applies brakes if a driver ignores a stop signal.
- Continuously monitors train speed against permitted limits, enforcing corrective actions if speeds differ.
Centralised Traffic Control and Remote Control
- Enhances economic efficiency by centralizing the control of signals and points across extensive rail stretches.
- Utilizes coded techniques for remote control of stations, improving overall line capacity.
Train Describer
- Displays train designations and positions to central control offices.
- Ensures controllers are informed of each train's status over monitored sections.
- Commonly integrated with centralized traffic control and remote control systems.
Definitions in Railway Signalling
- ACT: Refers to the Indian Railways Act, 1989.
- Adequate Distance: Defined as the distance necessary for safety measures.
- Approach Lighting: Automatically controlled lighting for signals upon train approach.
- Approved Special Instructions: Specific directives approved by the Commissioner of Railway Safety.
- Axle Counter: An electrical device for counting axles in and out to verify if a track section is clear.
Signal and Aspect Definitions
- Block Section: Area between two block stations; trains enter only after receiving a "Line Clear".
- Centralised Traffic Control: Governs train operations using fixed signals from a dedicated control location.
Warner Signal Details
- Night aspect indicators: green light appears above a red light; critical for driver perception.
- Different configurations exist when a Warner Signal is placed below a stop signal.
- No pre-warning is available with a Warner signal positioned under a stop signal.
Signal Arrangement and Location
- Warner Signal Placement: Can be placed independently or below stop signals, must be located a minimum of 1200 meters behind the first stop signal.
- Outer Signal: Functions as the first stop signal; must be positioned 400 meters in rear of potential block points.
- Home Signal: Placed near connections and facing points, necessary for protecting adjacent lines, with rules for distance and safety measures related to facing points.
Multiple Choice Facts
- Distant signals in single territories indicate proceed aspects relate to various operational conditions.
- Maximum aspects of LQ signals and distant signals in double distant signal territories are defined by safety regulations and operational guidelines.
General Signal Operations
- Signals for train movement control are critical for safe operations, requiring precise identification and regulation at stations.
- Proper signal function and positioning are essential for maintaining safe train operations across the railway network.
