We must have traveled in the Indian Railways🚂 once in our whole life. I have traveled a lot. And the maximum time🌀 of my one side traveling time like it is of 55⏰ hours or even sometimes more than that.
The Impact of this fog and low visibility on track: Indian railways provide the most important mode of the public transport 🌎system in India. It helps us to maintain the economy in many ways like by providing a fast 🌠and reliable 🤗mode of transport across the country. Northern railways are mostly affected by the foggy 🌨weather.
A case study... How 10 people killed in train accidents which happened due to foggy weather and low visibility. It happens when the Gorakhdhaam Express rammed into the Prayagraj Express near the Panki railway station in Kanpur around 9 am. Read more...

We must have traveled in the Indian Railways🚂 once in our whole life. I have traveled a lot. And the maximum time🌀 of my one side traveling time like it is of 55⏰ hours or even sometimes more than that.
But have you experienced a train🚈 journey in the winter time🌨? I am asking this because definitely your train was reached on its destination 🗽late by timing⏱ or even in the severe case may be it got canceled🤯 also.
*Please don't judge my English I haven't the Grammarly's premium subscription.*🤓
Also, Indian Railways🚈 is one of the world's🌎 largest railway network🛰 comprises of about 115,000 km🏁 (71,000 mi) of track 🚊over a route of around 67,312 km (41,826 mi) and 7,112 stations🏟. It has witnessed some major train 💥accidents over the years, which have claimed🙏 many lives😌 and injured 😥many people💛.
Due to fog ❄(or foggy weather), the visibility decreased on the track🚧, even sometimes it can be seen easily that there is zero visibility😵. Means you are not enough capable of seeing the nearest obstacle🗻 in front of you even if that obstacle is next to your step.

But due to low visibility😩, fog or mist the Indian railways🚝 are running late they also have to bear the cancellation of the train also. Due to cancellation❌ or late running of trains in foggy weather conditions especially in the northern railway, every year Indian railways has to bear the 💲loss of 1 Lakh Crore INR💲. Can you imagine🤯??

So, Indian Railways🚇 had to come with a solution😎. They tried many technologies💥 and lots of efforts😥 to solve this problem. To overcome this problem Indian railways came with various solutions which I😋 am compiling in this article📝 even it is very hard to juice out everything in a single article. But I will try my best to tell you everything which is scattered on the Internet. Ok, without any time waste Lets's begin😊
After failing many attempts, the Indian Railway ministry finally came up with a solution called TRINETRA. I am damn sure you are thinking about the third eyed god. When I heard about it for the first time then the same image was made in my mind. But it is not that thing which you are thinking about.
Basically, it is a system made by who and how a simple concept became a reality, I will mention further in the same article. It is a system which is made to challenge foggy weather and low visibility (Everyone knows😑). It consists of mainly three types of equipment which plays a major role in challenging the foggy weather.
First, one- High-quality optical video camera📷, the second one is High sensitivity Infrared thermal camera🔥 and the third one is radar-based terrain mapping system📡. We will understand one by one in the next step. The system helps in enhancing the vision of loco pilot to avoid train accidents.
1. High-quality optical video camera
This is a basic camera same as our phone camera. It is used to fetch real-time high-quality image which will be processed further for getting desired results. This is not that much important equipment. This type of two cameras is used for better vision.
2. High sensitivity Infrared thermal camera
It has a long range of view capability. With the help of this camera, the thermal imaging is done. What is thermal imaging? Thermal imaging works in environments without any ambient light. Thermal imaging can penetrate obscurants such as smoke, fog, and haze.
3. High sensitivity radar assisted system
Radar is a detection system which works on radio waves. It plays an important role in mapping terrain ahead of the locomotive. A radio wave is transmitted from the transmitter of the radar system and its travels further in the environment.
No any type of deep visible information has been shared by the Indian Railways or makers of Tri-Netra, So I have compiled only those information which I have found on the whole Internet.
Processing: When the output from all three equipment taken then it is further processed in a custom built-in intelligent system. Where all three outputs are composited together to give a single image. Basically, what it is doing, it is recording three images at real time and processing it in a computer to give a single processed image. The single processed image is shown on a monitor to the loco pilot (the train driver). Tri-Netra uses Infrared and Laser rays to detect any object on the tracks from the distance up to 2 Km.
About the image: It is a real-time image, means it is a moving image with a high frame rate. It is a black and white image or it seems like it is a negative of any colorful image. In which with the help of high-end computer vision, it makes a square and circle indicator on the humans, animals, and vehicles coming from ahead. And with another feature which I have observed in the trial run video. It can also detect signals and then make it more observable for the human eye by making dark every signal spot.
The system also maps the terrain ahead so that the driver knows when he is approaching a station or a signal. The terrain mapping is majorly done with the help of Radar-assisted system. What it does that a radio wave is transmitted forward ahead of the locomotive with the help of transmitter and its strikes on any obstruction and it came back with the same velocity (at the same velocity when it transmitted) then according to travel time the distance is calculated (The velocity of ultrasound wave). And according to the distance observed the computer become able to process the terrain mapping. For the testing video of Tri-Netra Click here
Range of Tri-Netra...
For vehicle and other trains- 1.8 Km
For Humans and animals- 700 Km
So, how was the concept came developed? Who was the personality to make its first prototype... Let's find out...
So, first of all, how the nomenclature has happened... Trinetra is a Hindi name which means the third eye. According to some websites it was named Trinetra because it can be a third eye of the Indian Railways locomotive. But on the other side, some are saying it was named Trinetra because it has a three vision system. And some are even also saying that because it has T-shaped device that's why it was named Trinetra.
But no any type of official statement is found by me on the internet. So, we can't say anything...
The first prototype was developed by Anand Kumar in CSIR-National aerospace laboratories under the research support of IIT BHU. Which looks like in the picture. Anand Kumar shows this prototype working with his smartphone. Any type of deep information has not shared by any authorities yet so we can't tell you about the algorithm behind this technology. Know more about Anand Kumar
The concept of TRI-NETRA was developed by Development Cell under the guidance of Member Mechanical, Railway Board while brainstorming on how to use the technology employed by fighter aircraft to see through clouds and operate in pitch darkness and the technology used by naval ships in mapping the ocean floor and navigating in the night.
