The horrific train accident in Odisha has left everyone shocked. This accident has once again raised serious questions about India's rail safety capability. According to reports, more than 288 people have been confirmed dead in this accident so far, while more than a thousand people have been injured.
Rail accidents, which include train derailments and collisions, can have devastating consequences and cause heavy casualties and extensive damage. The Odisha accident is the latest example of this.
However, as technology has evolved, so has our ability to prevent such accidents. Today, we look at the latest technology used to prevent train derailments and collisions, as well as countries that have been successful in implementing such safety measures.
How to prevent train accidents?
Advanced signaling system
The advanced signaling system is very important in modern trains. Trains in most countries are equipped with advanced signaling systems such as Positive Train Control (PTC). PTC technology uses a combination of GPS, wireless communication, and onboard computers to monitor and control train movements.
The PTC system uses communication-based and processor-based train control technology to robustly and efficiently prevent train-to-train collisions, over-speed derailments, and mispositioned switches. This technology can automatically apply the brakes if needed to prevent a potential collision.
Train Collision Avoidance System (TCAS)
Train Collision Avoidance Systems (TCAS) use radar, lidar, and other
sensor technologies to detect obstacles on the track, including other trains, vehicles, or pedestrians. These systems provide real-time alerts to training operators (loco pilots), enabling them to take immediate action to avoid collisions.
Automated Track Inspection (ATI)
Regular inspection of tracks is very important to identify potential hazards. In this situation, automatic track inspection i.e. automatic track inspection technique is very effective. Track geometry cars equipped with ATI technology, such as lasers and cameras, can quickly assess track conditions, and detect defects and irregularities. These cars are also called track recording cars. They are used to check various parameters of track geometry without disturbing the normal train operation. This allows for timely maintenance and repairs, reducing the risk of derailment.
Identification and maintenance of potential hazards
There are many techniques that can detect potential threats. Applying such techniques can help identify potential rail-related faults before they occur. By analyzing data from sensors such as temperature, vibration, and monitoring systems on trains, maintenance teams can detect early warning signs and take proactive measures to prevent accidents.
Advanced Communication System
Good communication between train operators, control centers, and maintenance personnel is essential to prevent accidents. Modern communication systems, including wireless data networks and real-time reporting tools, enable the rapid transmission of information. In such a situation, the accident can be avoided by coordinating one team with the other team and responding immediately in case of an emergency.
