A great invention by a guy from my hometown,Chittagong...his invention sends signal to a train, to a mobile phone and to the nearest train station instantly if the train track is cut off ahead of the train. The train track itself is used to send the signal.
This is very important for Bangladesh because there politically hired goons cut tracks to derail the train, to take revenge to create pressure on an opposition party. This technology can be installed anywhere in the world. Watch the video here.
