Mobile phones have been a source of communication for a little more or about10 years and they have been improved in the way they work, compatibility, design, durability and versatility. As they have improved, so have the frequencies which they use to transfer information. This brings us to the main idea of the topic, Mobile phones and trains. Mobile phones are everywhere nowadays but few people really care or even know what kind of diseases they can cause. Continuous use of mobile phones over a long period of time can cause damage to the ear and it could also affect the brain. It could also cause cancer. Use of mobile phones in public transports has also been a problem. Reports on trains especially have also caused significant problems. Mobile phones increasing frequency which is called “Radio Frequency” nowadays have now become very similar to that of the trains and can interfere with information passed to and from the train. The currently used frequency in some mobile phones which are called 3G, or third generation, is the generic term used for the next generation of mobile communications systems. The systems enhance the services available today and offer multimedia and internet access and the ability to view video footage. These services operate at 2100 MHz. (2.1GHz). This similarity in frequency causes interference in information transmission which can be quite critical in the case of trains because the information might be about where the train should not go to avoid a crash. This effect of mobile phones could also cause the government a lot of money in buying new trains, removing the wreckage of trains which are usually caused by mobile phones and pay the families of the harmed or dead on the crash. A recent train crash which was caused by mobile phones was on September 13, 2008. A Commuter train with 225 aboard slammed into a freight train on a winding route in Chatsworth. More than 135 are injured and 17 dead.
