TEXT С. THE TELEPHONE FINDS

APPLICAN ON RAILROADS
(1) The electromagnetic telephone was devised by Dr. A. G. Bell. It was in March, 1876, that Dr. Bell sent his first message (сообщение) by phone. A year later the first telephone apparatus was tested on the Pennsylvania railroad and then in California. Using the phones the track­men could warn the train crews of snow slides (оползни).

(2) The next year Bell produced an improved phone. The tests showed that the new apparatus was more speedy for dispatching than the telegraph.

(3) The regular operation of trains by phone was intro­duced in 1887. It proved so efficient that four years later the phone found a practical use on the train for providing direct communication between the conductors and the loco­motive drivers.
