Automatic Block Signalling (ABS)
Train detection and automatic signal control to support safe train separation and improved line capacity.
Automatic Block Signalling divides a railway line into a series of block sections. Track circuits or axle counters detect whether a section is occupied, and the signalling system uses this information to control the aspects shown to following trains.
As a train progresses, the relevant signals change according to section occupancy and the approved signalling arrangement. This helps maintain separation between successive trains and supports more efficient use of a busy railway corridor.
Param Enterprises Private Limited undertakes indoor and outdoor signalling works, including train detection equipment, signal installation, cable networks, system interfaces, testing, commissioning and maintenance.
Our Scope of Work
Key Advantages
Train Separation
Section occupancy information controls the signals that guide following trains, supporting safe spacing along the line.
Efficient Use of Line Capacity
Multiple block sections allow successive trains to use different parts of a corridor under the applicable operating rules.
Automatic Signal Operation
Signal aspects respond to train detection and system conditions, reducing the need for manual control of each block movement.
Project Execution Workflow
Corridor Survey & Interface Planning
Review the route, block section requirements, equipment locations and interfaces with station signalling.
Detection, Signals & Cable Installation
Install track circuits or axle counters, signal equipment, cable routes and associated connections.
Section & Signal Sequence Testing
Verify train detection, occupancy indications, signal aspect sequences and interfaces between adjacent sections.
Integrated Commissioning & Support
Coordinate system testing and commissioning, then provide handover records and maintenance support.
