    Why can't we use sensors in Train to avoid dangers?

    To understand what is sensor the best example is as we go any hotel we put our hand in the tap water will come out as we remove our hand water will go off so the basic idea is here there is no manual intervention to turn the tap on and off.Now if we explore this we can put this sensor in front of rails we can able to stop collision of rails, can stop moving train because of the bad condition of rail tracks, Can stop the deaths occurring of bad maintenance of railway crossings to curtail or reduce the manual intervention for the cause of human loss or proper running of train.Knowledgeable members, please post your view on this.

    The text book definition of sensors is as quoted below(Taken from textbooks): sensor is a device that detects and responds to some type of input from the physical environment. The specific input could be light, heat, motion, moisture, pressure, or any one of a great number of other environmental phenomena
    Sensors are used in many places. In various industries to control various parameters different types of sensors are being used. Generally my Idea about these sensors will work on some physical parameter like temperature or pressure or volume so on and so forth.
    I know there is a device called railway detonator which will be placed on a railway track and tied. When train passes over this the detonator will fire and explode. The uses of these items are as follows;
    A .
    A stop signal in dense fog, when signals are difficult to see
    A warning of a train stopped on the line ahead by an incident or accident—the train crew are usually responsible for placing the detonators
    A warning of ongoing engineering works ahead
    When a signaller or other railway employee requires to stop approaching trains in an emergency
    To alert crews working on the rails if a silent runaway train or train carriage is approaching
    How far it is practicable to have a sensor for stopping the vehicles are to be a matter for discussion among electronic engineers. If really one can be made it will be a good discovery.

    When we stand near the gate of lifts due to the sensor the gate does not close till the person move far from the gate. It is really a good one and the suggestion of the author is really a good and we should welcome. But above all we should apply our own sense which basically given to us by our God. We should not keep careless simply leave the job to the machine and sensor. We should also somewhat alert ourselves while working in the engine by expecting unforeseen events.

    While the suggestion mooted by the author is very good from the security and safety point of each passenger travelling on Indian Railways, what I see that there would be some technical glitch to which the Railways cannot use the sensors to detect the possible accident before hand. The sensors kept in the wash area could grasp the signal only few centimeters away from it. If that is taken as the parameter, how come a speeding train ranging between 80 to 120 kms can gauge a impending disaster which cannot be felt from far off. And the sensor with near distance wont do justice as the train cannot be stopped suddenly like that of bus or other vehicle and hence it cannot be implemented.

    Yes there should be any signal or sensor so if something will happen on line it will inform in the form of alarm. There may be different reason. Govt need to implement something on this.

    #608097 As my further study in Google reveals there are some countries who are using Train sensors
    A blunt knife or rusted knife can't be useful for anything just for the sake we call it as the knife similar to PayTM series or Sachin or Virat records.

    Bhushan, sensors are computer programmed device which can act on small gadgets of slow movement. But it cannot give full support to a moving train with high speed and heavy weight. That is my mention.

    Thought provoking post. Reading this in the background of recent sad events of train accidents and loss of human life, I began to wonder how are the so called super fast bullet train performing in the western countries. So instead of being repetitive, a quick search gave me some unbelievable statistics.

    1.Japan's Shinkasen (bullet train) has carried around 10 billion passengers (1964-2014). In 50 years they have never had a single human life lost due to derailment or collision. This is a fantastic record of safety when one considers that these trains travel around 200 miles/hour.

    2. France's TGV high speed trains (175-350 miles/hour) carrying billions of passengers in 3 decades never had a single loss of human life. There have been accidents at places while railway crossing were involved in some areas and in some cases human errors during testing.

    3. There are similar trains running in Germany, China with excellent safety record

    These figures are amazing and a tribute to engineering quality, man-machine co-ordination and most of all the excellent safety measures in place. Although not an expert in rail technology, some of the reasons I can think of the western success stories would be

    1. Quality of resources and construction
    2. Quality of infrastructure and maintainence
    3. Manpower
    4. excellent system of safety checks
    5. Almost religious adherence to protocols
    6. Accountability
    7. Maybe hefty legal and financial payout in case of human error leading on to an accident.
    8. Better funding

    If one does a honest similar analysis of why these accidents have happened, the answer often would be opposite of has been listed above.May be we can take a leaf out of the book of the bullet train record and see what lessons we can learn and more importantly what measures are suitable for the Indian railway scenario.

    608161 is a good response adding information. Definitely it will be worth to draw lessons by comparison.

    However we can give some allowance to ourselves due to the land size and population. Probably we should compare ourselves to China, as some of the parameters are similar.
    However as we have almost achieved the essential basic requirements of the services, now our endeavour should be on flawless safety.
