He made it possible for moving trains to have telegraphs.


One of Woods’ invention was the "synchronous multiplex railway telegraph" (1887), which allowed messages to be sent to and from moving trains and different train stations, enabling train conductors and engineers to avoid collisions and report hazards on tracks ahead, providing for greater safety and a decrease in railway accidents.
