Automated Rainfall Monitoring System Ensures Safety for Mumbai-Ahmedabad Bullet Train

AHMEDABAD,GUJARAT : The Mumbai-Ahmedabad Bullet Train project has incorporated a state-of-the-art Automated Rainfall Monitoring System to further improve the safety of its operations. This state-of-the-art system is created to offer up-to-the-minute rainfall data, crucial for preserving the reliability of the rail infrastructure and guaranteeing the safety of passengers.

The monitoring system uses high-tech rain gauges with state-of-the-art instrumentation. Every gauge is equipped with a tripping cell that produces signal pulses when it detects the amount of rainfall collected. The pulses are transmitted through a signal communication line to the Facility Controller System at the Operation Control Centre (OCC), where the control team carefully displays and monitors the data.

The system offers two essential rainfall measurements:

Hourly Rainfall: This is the measurement of rainfall that has been recorded within the past hour.

Rainfall in the past 24 hours: The total amount of rain that has fallen within the last day.

Accurate measurements play a crucial role in making well-informed decisions regarding the operation of Mumbai-Ahmedabad Bullet train, particularly in regions that are susceptible to heavy rainfall. This is because heavy rainfall can have a significant impact on earth structures and natural slopes. Specific regulations will be enforced to ensure safety, based on the rainfall data and predefined threshold values for different types of earth structures and slopes. Patrolling teams activated through Maintenance Centres will verify these threshold values and closely monitor conditions on the ground.

In order to provide extensive coverage, a total of six rain gauge stations will be set up along the Mumbai-Ahmedabad Bullet Train route, with a particular focus on the Thane and Palghar districts.

Strategically located stations will be positioned near vulnerable earth structures, mountain tunnel entrances and exits, tunnel portals, and areas with significant cuttings and potential landslide risks. Every rain gauge station has a wide reach of almost 10 kilometers, guaranteeing extensive monitoring coverage along important sections of the route.
