Michigan Central Putting in the Latest Invention

Will Be Able to Both Telegraph and Telephone Over Same Wire

The telegraphone, which enables the use of telegraph wires simultaneously for telegraphing and telephoning, has been adopted by the Michigan Central road, says the Detroit Tribune. The system is already in operation between Detroit and St. Thomas, 111 miles, and between Chicago and Michigan City. The entire system will be equipped with the instruments as soon as possible, the Michigan Central being the first road in the country to take this course.

The apparatus used at both the sending and receiving points is very much like a telephone. For each set of instruments the company that controls the patents and supplies the instruments is paid $12 a year. For the operating department of a railroad the service is said to be of inestimable advantage. If, for instance, an operating official at Detroit wants to communicate quickly with an operating official in another city he simply touches a button in his office and the bell rings in the distant office of the other official, which is the signal that somebody wants to speak to him. The conversation then begins over the telegraph wire, while the telegraph operator on the same wire is entirely oblivious of it.
