Abstract
A new method of radio-telephonic conversation between a moving train and a stationary instrument is announced from Canada, where it has been successfully carried out on the Canadian National Railway lines. The new device throws the voice from the train to the telegraph wires which line the right-of-way of every railroad. It is then carried to the terminal point and there connected with the ordinary telephone lines. This process is reversed as regards the other participant in the conversation. As the system now stands, the terminal points must be not more than about 150 miles apart or the voice is lost. A two-hour conversation was held in this way on May 5, and several points of advantage over the German system are claimed. Experiments in perfecting the system were carried on by J. C. Burkholder, formerly with the Bell laboratory at Newark, N. J. Electrical World.
