Page - Operators must have the proper appliances for hand signaling ready for immediate use if the fixed signal should fail to work properly If a signal is not displayed at a night office, trains which have not been notified must stop and ascertain the cause, and report the facts to the Superintendent from the next open telegraph office.

Where the semaphore is used, the arm indicates "stop. The Railway Telegraphy System. Back in the s trains were becoming a vital way of transportation.

They were being utilized much more often now that engineers had invented more efficient ways to run them. However, one thing was missing, and Granville T. Woods saw what had yet to be seen. Train crashes were frequent and very costly. Telegraphy made it possible for information to travel much faster than the fastest means of transport—the railway.

The telegraph became essential to the efficient management of newly emerging railways in Britain, but it quickly expanded to more general communication.

Thurston (–), publisher of the trade journal Railroad Telegrapher, in Vinton, Iowa, the group formed the Order of Railway Telegraphers of North America, with membership limited to telegraphers who were or who had been employed in railroad service.

Telegraphy is the long-distance transmission of textual messages where the sender uses symbolic codes, known to the recipient, rather than a physical exchange of an object bearing the message. Thus flag semaphore is a method of telegraphy, whereas pigeon post is not.

An electrical telegraph was a point-to-point text messaging system, used from the s until better systems became widespread.

It used coded pulses of electric current through dedicated wires to transmit information over long distances. It was the first electrical telecommunications system, the most widely used of a number of early messaging systems called telegraphs, devised to send text.

Before aboutthe term wireless telegraphy was also used for other experimental technologies for transmitting telegraph signals without wires, such as electromagnetic induction, and ground conduction telegraph systems.

Radiotelegraphy was the first means of radio communication.

One of the most common uses for telegraphs in the United States was for the railroad lines. Telegraphy made it possible to know when trains were leaving and when they should be expected to arrive, which in turn streamlined the railroad industry.
