Hint: Granville Woods, Woods was an inventor in the United States who held more than 60 patents. After the Civil War, he was the first African American mechanical and electrical engineer. He contributed to the railroad industry by providing various inventions.
Complete answer: A system Granville Woods referred to as the Synchronous Multiplex Railway Telegraph, a variant of the induction telegraph that relied on ambient static electricity from existing telegraph lines to transmit messages between train stations and moving trains, was one of Woods' significant inventions.
Granville Woods received more than 50 patents during the course of his life for inventions including an automatic brake, an egg incubator, and for improvements to other innovations such as safety circuits, telephones, and phonographs. The system he referred to as "telegraphony" would allow a telegraph station to send voice and telegraph messages over a single wire via Morse code. He sold to the American Bell Telephone Company the rights to this system. He invented the Synchronous Multiplex Railway Telegraph in 1887, which allowed moving trains to communicate between train stations by generating a magnetic field around a coiled wire under the train. Allowing messages to be transmitted to and from moving trains and various train stations, allowing train drivers and engineers to prevent collisions and report hazards on tracks ahead, ensuring greater protection and a decrease in rail accidents.
Note: On January 30, 1910, Woods died from a cerebral haemorrhage at Harlem Hospital in New York City, having sold a variety of his products to companies such as Westinghouse, General Electric and American Engineering.
