Devices for sending and receiving intelligent information were needed to improve communication on the railways. One such piece of apparatus was the Needle Telegraph, devised by William Fothergill Cooke and Charles Wheatstone, in 1936, from an idea by Baron Pawel Schilling, demonstrated around 1832.
Information could be read if a needle was moved to the left or right. The single needle unit was a further development of Wheatstone and Cookes 5 needle system, which did not use Morse Code, and was replaced by the single needle system, which would be used in signal boxes around the World for the next 100 years. This unit is clearly marked with the complete alphabet in Morse code on the face.
