MSDAC to Combat Waterlogging in Sealdah Division: Ensuring Uninterrupted Rail Services
- •Sealdah Division faces waterlogging issues, and MSDAC technology will be implemented to maintain rail services.
- •MSDAC (Multi-Section Digital Axle Counter) detects train wheels/axles, unlike traditional electrical track circuits.
- •Waterlogging can compromise DC Track Circuits, but MSDAC accurately determines train location using axle detectors.
- •This technology does not prevent waterlogging but enhances signaling reliability and aids train movement.
- •The 8-crore rupee project will address waterlogging problems in stations like Dattapukur, Barasat, and Canning on the Sealdah-South branch.
Key Questions Answered
MSDAC utilizes axle detectors positioned at specific locations on the railway tracks to identify train wheels and axles, determining whether a section is clear by comparing the number of axles entering and exiting.
MSDAC provides an independent secondary train-detection system that builds redundancy to accurately determine train locations even when track circuits experience problems during the monsoon season, thereby increasing signaling availability and reliability.
According to railway sources, the total cost of implementing the MSDAC project to help maintain rail services during waterlogging was eight crore rupees.
