Newscopy: "MOVING FINGER CHARTS MUNI MOVEMENTS--Chief Inspector Herbert Wilson and Earle A. Rambo, assistant director, watch an automatic device which records the extent to which N, B and C streetcar lines keep on schedule. A radio car is dispatched to the scene whenever a delay is observed, with an inspector instructed to 'get the cars back on the timetable.' Eventually, all lines are expected to be monitored by the recording device."
