The system is operated in a closedcircuit and is so arranged that anyfailure of the current supply curtailinga signal will set that signal at thestop position, when the crew of anapproaching train will be required toget into communication with the dis-patcher to obtain authority to pro-ceed. For single track lines doublelenses are provided to show the lightsignal in both directions. The selec-tive signaling system may be con-nected direct to the ordinary train dis-patchers telegraph or telephone wirewithout interfering with the service atother stations where semaphore sig- nals are not installed. They will workas far as a telegraphic impulse can bemade effective. Extending Telephone Intercourse.
