Granville T. Woods: Railway Telegraph
About/What I Learned:
•The railway telegraph is used to communicate between train stations and moving trains.
•It also helped trains know exactly where they are at all times.
•It was significant because it improved railway safety, decreased accidents, and helped engineers and dispatchers know where other trains are.
•It works by having a suspended coil beneath the train and it has a current that generates a magnetic field. There is also a wire running beside the tracks and as the train moves it creates a magnetic field and this is what helps connect the signal.
•The signalmen tap out their messages on signal boxes. Each signal box has an identifying the number and each type of train has an identifying code.
•Signalmen had to communicate to each other to receive a train into their section, or to send it on to the next.
•He also had to record train movements in his log book.
•Before the telephone was created a complex set of telegraphic codes (the Morse code) had to be learned, so that this could be done efficiently.

Improvements:
My partner and I have improved Granville T. Woods invention by adding a 4G iPad and Bluetooth. We intend to work with apple to create a program that shows a map of all the railroads and stations. Since the iPad is 4G it will be able to track and show where all of the trains are at all times. There will also be a notepad, so that signalmen can log everything that happens instead of using a bunch of paper.The Bluetooth will be used to communicate to other trains and signalmen without having to tap out a message or even use their hands at all.This is eco-friendly because it doesn't use paper and all you have to do is charge them instead of having them plugged in the whole time.
