TIME TABLES 4. Each Time Table, from the moment it takes effect, supersedes the preceding Time Table, and its schedules take effect on any division or sob-division, at the leaving time at their initial stations on such division, or sob-division. But when a schedule of the preceding Time Table corresponds in number, class, day of leaving, direction, and initial and terminal stations with a schedule of the new Time Table, a train authorized by the preceding Time Table will retain its train orders and assume the schedule of the corresponding number of the new Time Table. Schedules on each division, or subdivision, date from their initial stations on such division, or sub-division. Not more than one schedule of the same number and day shall be in effect on any division, or sub-division. 5. Not more than two times are given for a train at any station; where one is given, it is, unless otherwise indicated, the leaving time; where two, they are the arriving and the leaving time. The time applies at the switch where an opposing train clears; where there is no switch, it applies at the station. Schedule meeting or passing stations are indicated by figures in full-faced type. Both the arriving and leaving time of a train are in full-faced type when both are meeting or passing times or when one or more trains are to meet or pass it between those times. Where there are one or more trains to meet or pass a train at any station, attention is called to it by the numbers of the trains to be met or passed in small figures adjoining. 6. The following letters when placed before the figures of the schedule indicate: L--leave; A--arrive; S--regular stop; F--fiat stop to receive or discharge traffic; C--conditional stop. See Time Table Footnote; Z--stop to change engines.
