ELECTRICAL RECORDING CLOCKS

Recording clocks have been installed in the entrance hall to the general offices of the London Underground Railways group. Those clocks consist of a dial covering twenty-four hours, and arc connected up electrically with a contact lever on the track, so that every train passing over a given point records the time of its passage upon the clock face, and observation of the clock face shows the regularity with which the service is being maintained. Separate clocks arc provided for each railway. If, however, the service is not working smoothly and gaps appear upon the clock, the clock itself affords no explanation of what lias occurred. It is, therefore, proposed to install in conjunction with the clock a machine which will set out particulars of the incident causing the derangement, stating where it is and what has occurred, and what changes are necessary to correct it.

These news-recording instruments will be installed at all tho depots, so that the engineering and operating staffs will be advised at once and simultaneously of tho occurrence. They will be operated from the controller’s office at Leicester Square for the tube railways, and at Earl’s Court for the district railway. By this means it is hoped to mitigate any delay which may follow a mishap and to improve tho standard of operation upon tho railways as a whole.
