THE RAILOPHONE.

WONDERFUL DEMONSTRATIONS. "Remarkable demonstrations of the Von Kramer wireless inductive system as applied to doublo automatic train signalling ?o Cro i g /, vcn at Stratford-ou-Avon on June 2b. J. ho demonstrations, included railographing a message from a station to a train, warning a moving train by audible signal, signalling to a station from a moving train, stopping a train in motion irom a station, automatically stopping a train in motion, preventing a train from entering a section, fog-signalling, ami the reproduction of conditions which have led to serious railway accidents.'. The latter experiment was especially interesting. A slow train entered the section under normal conditions, and proceeded slowly in the section'. A fast train then entered the same section against the danger signal, and by means of the wireless apparatus boih trains were automatically brought to a standstill, thus proving that a. collision with this precaution was impossible. A second experiment was tried with a train travelling from Ettington towards Stratford on the down line. While in the middle of tho section a second train entered the same section, also on the down line, from the Stratford end. Both were automatically pulled up, and a collision which in other circumstances would have occurred was prevented by means of this apparatus, In another experiment a visitor was called upon to press a button on the platform, and thereby to pull up by mechanical means tho train 6teaming full speed two miles away. , In demonstrating the use. of the railophone in the case of distress signalling a train was taken some two hundicd vards out of tho station, and a powerful 'hooter was caused to sound on it by closing the switch in the signal cabin. In a similar way alarm signals were sent from the train, when it was actually moving, to the station and vice versa, this bein" done with tho object of showing that every precaution could be taken to forestall an accident if in actual practice it was found that a train was running into danger or a driver of a train wished to warn a man in the signal-box.
