Further Explanation
In 1887, woods invented the induction telegraph system which allows men, through the use of wires, to communicate their voices thereby speeding up important communications.
The induction telegraph helps the trains not to engage in any form of accident while moving on the railway tracks. Also dispatchers are able to locate trains through the use of the induction telegraph.
As a result of the invention, the inventor became more popular, more especially as the ''BLACK EDISON'' solely because of his invention and refusal to partnership with Thomas Edison.
