Abstract
FACSIMILE telegraphy is one of the devices recently called upon by the railways to help meet the unprecedented demands of to-day. It has many advantages over other forms of communication for several railway applications. For example, its inherent accuracy makes it an ideal method for the handling of train orders and once the order is prepared for transmission it need never again be copied manually. The possibility of transmission error is greatly reduced by the fact that the method can operate through extremely high levels of interference. Simplicity of operation and the ease with which duplicate copies may be secured are additional advantages. Automatic recorders, housed in small shacks along the right-of-way, are located at sidings, branches, crossings-wherever a train might be required to stop. Recorders may also be installed in small stations where telegraph service is not provided. An automatic transmitter, under control of the operator for the district, is arranged so that he may transmit orders to any of these recorders.
