40METRO RAIL NEWS -MAY - 2025 www.metrorailnews.in Cloud Computing in Rail Infrastructure: Cloud computing refers to the delivery of computing services, such as servers, storage, databases, networking, software applications, and advanced technologies like data analytics and artificial intelligence, over the internet. This model offers scalable and flexible infrastructure for processing and analysing large volumes of data, which is essential for modern rail systems. Cloud platforms enable rail operators to store and process massive datasets which is generated from various sources, including ticketing systems, train operations, passenger flow sensors, CCTV, and maintenance records.One of the main benefits of cloud computing is its ability to scale resources on demand. This eliminates the need for costly on-premises infrastructure and provides flexibility. This allows rail operators to adapt their resources as required, based on operational demands.Example%u2022 Data collected from various systems, such as ticketing, train operations, passenger flow sensors, CCTV cameras, and maintenance records, can be archived in a cloud database. This configuration makes better analysis and management of the operations possible.These technologies work in conjunction with essential systems, including the signalling system, Public Information System, and Ticketing System, which will be discussed in the subsequent sections.1. Signalling System: Enabling Safe and Efficient Train Movements%u2022The signalling system in a metro network is a crucial component that ensures the safe and efficient movement of trains by preventing collisions between trains, over-speeding, and derailments. %u2022 The signalling system uses a combination of wayside and onboard equipment like signals, train detection, interlocking, and automatic protection systems to ensure train safety and adherence to schedules.%u2022 In the era of smart metro systems, Communications-Based Train Control (CBTC) signalling system has emerged as a better alternative for effectively utilising the full capacity of rolling stock and associated rail infrastructure. CBTC increases the reliability and flexibility of train operations by facilitating real-time communication between trains and infrastructure.Example:India's first indigenously developed Signalling System: In February 2023, the Delhi Metro launched the country%u2019s first indigenously developed signalling system, the Automatic Train Supervision system, i-ATS. This system was jointly developed by Bharat Electronics Limited (BEL) and DMRC under the %u2018Make in India%u2019 and %u2018AatmaNirbhar Bharat%u2019 initiatives. The system has been deployed on the Red Line corridor. GLOBAL / TRENDING
